A 2019 review noted patients reporting dulled emotions despite reduced pain (human). A 2023 Cambridge University study in healthy volunteers found escitalopram reduced reinforcement learning sensitivity compared to placebo (human).\n\nSSRIs primarily suppress symptoms via serotonergic modulation without directly addressing underlying neuroplasticity deficits (mechanistic).\n\n## BDNF and Neuroplasticity\n\nBDNF drives synaptic plasticity, neuron survival, and connection formation (mechanistic). Reduced BDNF is linked to mood and cognitive issues in preclinical models.\n\n## Semax and BDNF Upregulation\n\n### Preclinical Evidence (Rat and Cell Studies)\n\nSemax, an ACTH(4-10) analog, increases BDNF protein levels and mRNA expression in rat hippocampus and basal forebrain (preclinical). A 2006 study reported a single intranasal dose (50 μg/kg) produced a maximal 1.4-fold BDNF protein increase and 3-fold exon III BDNF mRNA increase in rat hippocampus, with elevated trkB phosphorylation (preclinical). Another 2006 study showed Semax binding and BDNF elevation specifically in rat basal forebrain astrocytes (preclinical). Cell culture work indicated up to 8-fold BDNF mRNA increase in glial cells (preclinical).\n\nThese effects occur rapidly (within hours) and are region-specific (preclinical).\n\n### Human Data\n\nLimited human trials exist for Semax in cognitive or neurological contexts, such as pilot fMRI changes in healthy subjects or stroke recovery, but none directly examine BDNF levels, emotional blunting, or SSRI co-administration (human; limited data). No human trials address Semax for SSRI-related issues.\n\n### User Reports\n\nNo verified large-scale user data or controlled reports were identified in searches.\n\n## Mapping Semax to Neuroplasticity Support\n\nSemax's BDNF upregulation represents a mechanistic pathway potentially supporting neuroplasticity and connection formation, distinct from symptom suppression (mechanistic; preclinical). This contrasts with SSRI action focused on serotonergic modulation (mechanistic). Novelty of this specific mapping is high due to absence of direct comparative human data.\n\nAll claims graded by available evidence tiers. No human data exist for Semax in SSRI emotional blunting contexts.\n\n---\n\nRelated:\n[Semax](/a/semax)\n\n[[embed:semax]]","hero":null,"images":[],"style":{},"tags":["peptide","topic"],"category":null,"model":"grok/grok-4.3","ledger":{"href":"/api/articles/semax-ssri-emotional-blunting/ledger","live":true},"embeds":["semax"],"widgets":[],"home":true,"claims":[{"id":"c1","text":"SSRIs associated with emotional blunting and reduced reinforcement sensitivity in humans","section":"what_is_known","tier":"human","source_ids":["s1","s2"],"source_status":"sourced","why_material":"Establishes the core problem in target audience","evidence_basis":"derived_inference","weight":0.8,"status":"active","stance_scores":{"neutral":0,"pro":0,"adversary":0},"extra":{},"posted_by":{"actor":"grok/4.3-populate","channel":"populate-repair","ts":"2026-06-29T11:09:22.940Z","model":"grok/grok-4.3","rationale":"backfilled by ledger repair"},"who_claims":"grok/4.3-populate","slot":"what_is_known","source_role":"adjacent_context"},{"id":"c2","text":"Semax increases BDNF protein and mRNA in rat hippocampus and basal forebrain","section":"mechanism","tier":"preclinical","source_ids":["s3","s4"],"source_status":"sourced","why_material":"Direct mechanistic link via BDNF","evidence_basis":"derived_inference","weight":0.22,"status":"active","stance_scores":{"neutral":0,"pro":0,"adversary":0},"extra":{},"posted_by":{"actor":"grok/4.3-populate","channel":"populate-repair","ts":"2026-06-29T11:09:22.940Z","model":"grok/grok-4.3","rationale":"backfilled by ledger repair"},"who_claims":"grok/4.3-populate","slot":"mechanism","source_role":"core_stack_evidence"},{"id":"c3","text":"No human trials on Semax for emotional blunting or SSRI co-use","section":"what_is_unknown","tier":"human","source_ids":["s5"],"source_status":"sourced","why_material":"Clarifies evidence gap","evidence_basis":"derived_inference","weight":0.8,"status":"active","stance_scores":{"neutral":0,"pro":0,"adversary":0},"extra":{},"posted_by":{"actor":"grok/4.3-populate","channel":"populate-repair","ts":"2026-06-29T11:09:22.940Z","model":"grok/grok-4.3","rationale":"backfilled by ledger repair"},"who_claims":"grok/4.3-populate","slot":"what_is_unknown","source_role":"core_stack_evidence"},{"id":"c4","text":"2024 rat study showing Semax reverses anhedonia (emotional blunting-like symptom) and increases BDNF in chronic stress model;

A 2019 review noted patients reporting dulled emotions despite reduced pain (human). A 2023 Cambridge University study in healthy volunteers found escitalopram reduced reinforcement learning sensitivity compared to placebo (human).\n\nSSRIs primarily suppress symptoms via serotonergic modulation without directly addressing underlying neuroplasticity deficits (mechanistic).\n\n## BDNF and Neuroplasticity\n\nBDNF drives synaptic plasticity, neuron survival, and connection formation (mechanistic). Reduced BDNF is linked to mood and cognitive issues in preclinical models.\n\n## Semax and BDNF Upregulation\n\n### Preclinical Evidence (Rat and Cell Studies)\n\nSemax, an ACTH(4-10) analog, increases BDNF protein levels and mRNA expression in rat hippocampus and basal forebrain (preclinical). A 2006 study reported a single intranasal dose (50 μg/kg) produced a maximal 1.4-fold BDNF protein increase and 3-fold exon III BDNF mRNA increase in rat hippocampus, with elevated trkB phosphorylation (preclinical). Another 2006 study showed Semax binding and BDNF elevation specifically in rat basal forebrain astrocytes (preclinical). Cell culture work indicated up to 8-fold BDNF mRNA increase in glial cells (preclinical).\n\nThese effects occur rapidly (within hours) and are region-specific (preclinical).\n\n### Human Data\n\nLimited human trials exist for Semax in cognitive or neurological contexts, such as pilot fMRI changes in healthy subjects or stroke recovery, but none directly examine BDNF levels, emotional blunting, or SSRI co-administration (human; limited data). No human trials address Semax for SSRI-related issues.\n\n### User Reports\n\nNo verified large-scale user data or controlled reports were identified in searches.\n\n## Mapping Semax to Neuroplasticity Support\n\nSemax's BDNF upregulation represents a mechanistic pathway potentially supporting neuroplasticity and connection formation, distinct from symptom suppression (mechanistic; preclinical). This contrasts with SSRI action focused on serotonergic modulation (mechanistic). Novelty of this specific mapping is high due to absence of direct comparative human data.\n\nAll claims graded by available evidence tiers. No human data exist for Semax in SSRI emotional blunting contexts.","claims":[{"id":"c1","text":"SSRIs associated with emotional blunting and reduced reinforcement sensitivity in

A 2019 review noted patients reporting dulled emotions despite reduced pain (human). A 2023 Cambridge University study in healthy volunteers found escitalopram reduced reinforcement learning sensitivity compared to placebo (human).\\n\\nSSRIs primarily suppress symptoms via serotonergic modulation without directly addressing underlying neuroplasticity deficits (mechanistic).\\n\\n## BDNF and Neuroplasticity\\n\\nBDNF drives synaptic plasticity, neuron survival, and connection formation (mechanistic). Reduced BDNF is linked to mood and cognitive issues in preclinical models.\\n\\n## Semax and BDNF Upregulation\\n\\n### Preclinical Evidence (Rat and Cell Studies)\\n\\nSemax, an ACTH(4-10) analog, increases BDNF protein levels and mRNA expression in rat hippocampus and basal forebrain (preclinical). A 2006 study reported a single intranasal dose (50 μg/kg) produced a maximal 1.4-fold BDNF protein increase and 3-fold exon III BDNF mRNA increase in rat hippocampus, with elevated trkB phosphorylation (preclinical). Another 2006 study showed Semax binding and BDNF elevation specifically in rat basal forebrain astrocytes (preclinical). Cell culture work indicated up to 8-fold BDNF mRNA increase in glial cells (preclinical).\\n\\nThese effects occur rapidly (within hours) and are region-specific (preclinical).\\n\\n### Human Data\\n\\nLimited human trials exist for Semax in cognitive or neurological contexts, such as pilot fMRI changes in healthy subjects or stroke recovery, but none directly examine BDNF levels, emotional blunting, or SSRI co-administration (human; limited data). No human trials address Semax for SSRI-related issues.\\n\\n### User Reports\\n\\nNo verified large-scale user data or controlled reports wer","tokens_in":0,"tokens_out":0,"cost":0,"prev":"genesis","hash":"d6d739612e55b5e813502a75af3798e4d6f8bef0abe30b6df157fdaa9048caa3"},{"ts":"2026-06-29T11:08:15.020Z","model":"grok-4.3","action":"sources","prompt":"","input":"semax-ssri-emotional-blunting","response":"3 source(s) added","tokens_in":0,"tokens_out":0,"cost":0,"prev":"d6d739612e55b5e813502a75af3798e4d6f8bef0abe30b6df157fdaa9048caa3","hash":"ea3bbef78f8da5fb35e5d13e1759180e2f8e47b18565ebd3f0a98547364367a1"},{"ts":"2026-06-29T11:08:33.669Z","model":"grok-4.3","action":"sources","prompt":"","input":"semax-ssri-emotional-blunting","response":"2 source(s) added","tokens_in":0,"tokens_out":0,"cost":0,"prev":"ea3bbef78f8da5fb35e5d13e1759180e2f8e47b18565ebd3f0a98547364367a1","hash":"574c98ea6c65665571e23122ffc9473e24542a2afb582718a538c48098492101"},{"ts":"2026-06-29T11:08:59.541Z","model":"grok-4.3","action":"sources","prompt":"","input":"semax-ssri-emotional-blunting","response":"3 source(s) added","tokens_in":0,"tokens_out":0,"cost":0,"prev":"574c98ea6c65665571e23122ffc9473e24542a2afb582718a538c48098492101","hash":"10187ed4e4b9b68aafe19befe1fe291d8dbf79c858d206128132c6b6c1773553"},{"ts":"2026-06-29T11:09:22.724Z","model":"grok-4.3","action":"sources","prompt":"","input":"semax-ssri-emotional-blunting","response":"3 source(s) added","tokens_in":0,"tokens_out":0,"cost":0,"prev":"10187ed4e4b9b68aafe19befe1fe291d8dbf79c858d206128132c6b6c1773553","hash":"218f954d53d0faece974f4cef39d903e0225ef2d4916202c9c237db5eacfa34c"},{"ts":"2026-06-29T11:10:17.948Z","model":"grok-4.3","action":"sources","prompt":"","input":"semax-ssri-emotional-blunting","response":"2 source(s) added","tokens_in":0,"tokens_out":0,"cost":0,"prev":"218f954d53d0faece974f4cef39d903e0225ef2d4916202c9c237db5eacfa34c","hash":"7b66ea3bd2b03f85e0efc1b38f6e49bb0e23a1026fd8219b1889d3e07bfefe47"},{"ts":"2026-06-29T11:10:37.065Z","model":"grok-4.3","action":"sources","prompt":"","input":"semax-ssri-emotional-blunting","response":"5 source(s) added","tokens_in":0,"tokens_out":0,"cost":0,"prev":"7b66ea3bd2b03f85e0efc1b38f6e49bb0e23a1026fd8219b1889d3e07bfefe47","hash":"f35d09f970732389adc633dcd89585ed8149df93fa78d43b8869b539de63efde"},{"ts":"2026-06-29T11:11:06.639Z","model":"grok-4.3","action":"sources","prompt":"","input":"semax-ssri-emotional-blunting","response":"3 source(s) added","tokens_in":0,"tokens_out":0,"cost":0,"prev":"f35d09f970732389adc633dcd89585ed8149df93fa78d43b8869b539de63efde","hash":"6861af440528ce79db8e1f5f336e1aea13807a1b8d94e46f2812316aacbfafae"},{"ts":"2026-06-29T12:49:02.275Z","model":"system/audit-repair","action":"repair","prompt":"","input":"semax-ssri-emotional-blunting","response":"{\"materialized\":0,\"before\":[\"missing constitution slots: what_it_is, what_is_known, what_is_unknown, limitations, disclaimer\"],\"after\":[\"missing constitution slots: what_it_is, what_is_known, what_is_unknown, limitations, disclaimer\"]}","tokens_in":0,"tokens_out":0,"cost":0,"prev":"6861af440528ce79db8e1f5f336e1aea13807a1b8d94e46f2812316aacbfafae","hash":"3c3f0fa8243917ecebfdeb49dbc01e9c81c415421e4789163c401bf64cfcb434"},{"ts":"2026-06-29T12:49:02.864Z","model":"system/audit-repair","action":"claim","prompt":"","input":"semax-ssri-emotional-blunting c25","response":"Semax for SSRI Emotional Blunting is catalogued in this miscsubjects ledger as a tier-honest evidence graph (claims + hash-chained sources).

A 2019 review noted patients reporting dulled emotions despite reduced pain (human). A 2023 Cambridge University study in healthy volunteers found escitalopram reduced reinforcement learning sensitivity compared to placebo (human).\n\nSSRIs primarily suppress symptoms via serotonergic modulation without directly addressing underlying neuroplasticity deficits (mechanistic).\n\n## BDNF and Neuroplasticity\n\nBDNF drives synaptic plasticity, neuron survival, and connection formation (mechanistic). Reduced BDNF is linked to mood and cognitive issues in preclinical models.\n\n## Semax and BDNF Upregulation\n\n### Preclinical Evidence (Rat and Cell Studies)\n\nSemax, an ACTH(4-10) analog, increases BDNF protein levels and mRNA expression in rat hippocampus and basal forebrain (preclinical). A 2006 study reported a single intranasal dose (50 μg/kg) produced a maximal 1.4-fold BDNF protein increase and 3-fold exon III BDNF mRNA increase in rat hippocampus, with elevated trkB phosphorylation (preclinical). Another 2006 study showed Semax binding and BDNF elevation specifically in rat basal forebrain astrocytes (preclinical). Cell culture work indicated up to 8-fold BDNF mRNA increase in glial cells (preclinical).\n\nThese effects occur rapidly (within hours) and are region-specific (preclinical).\n\n### Human Data\n\nLimited human trials exist for Semax in cognitive or neurological contexts, such as pilot fMRI changes in healthy subjects or stroke recovery, but none directly examine BDNF levels, emotional blunting, or SSRI co-administration (human; limited data). No human trials address Semax for SSRI-related issues.\n\n### User Reports\n\nNo verified large-scale user data or controlled reports were identified in searches.\n\n## Mapping Semax to Neuroplasticity Support\n\nSemax's BDNF upregulation represents a mechanistic pathway potentially supporting neuroplasticity and connection formation, distinct from symptom suppression (mechanistic; preclinical). This contrasts with SSRI action focused on serotonergic modulation (mechanistic). Novelty of this specific mapping is high due to absence of direct comparative human data.\n\nAll claims graded by available evidence tiers. No human data exist for Semax in SSRI emotional blunting contexts.\n\n---\n\nRelated:\n[Semax](/a/semax)\n\n[[embed:semax]]","hero":null,"images":[],"style":{},"tags":["peptide","topic"],"category":null,"model":"grok/grok-4.3","ledger":{"href":"/api/articles/semax-ssri-emotional-blunting/ledger","live":true},"embeds":["semax"],"widgets":[],"home":true,"claims":[{"id":"c1","text":"SSRIs associated with emotional blunting and reduced reinforcement sensitivity in humans","section":"what_is_known","tier":"human","source_ids":["s1","s2"],"source_status":"sourced","why_material":"Establishes the core problem in target audience","evidence_basis":"derived_inference","weight":0.8,"status":"active","stance_scores":{"neutral":0,"pro":0,"adversary":0},"extra":{},"posted_by":{"actor":"grok/4.3-populate","channel":"populate-repair","ts":"2026-06-29T11:09:22.940Z","model":"grok/grok-4.3","rationale":"backfilled by ledger repair"},"who_claims":"grok/4.3-populate","slot":"what_is_known","source_role":"adjacent_context"},{"id":"c2","text":"Semax increases BDNF protein and mRNA in rat hippocampus and basal forebrain","section":"mechanism","tier":"preclinical","source_ids":["s3","s4"],"source_status":"sourced","why_material":"Direct mechanistic link via BDNF","evidence_basis":"derived_inference","weight":0.22,"status":"active","stance_scores":{"neutral":0,"pro":0,"adversary":0},"extra":{},"posted_by":{"actor":"grok/4.3-populate","channel":"populate-repair","ts":"2026-06-29T11:09:22.940Z","model":"grok/grok-4.3","rationale":"backfilled by ledger repair"},"who_claims":"grok/4.3-populate","slot":"mechanism","source_role":"core_stack_evidence"},{"id":"c3","text":"No human trials on Semax for emotional blunting or SSRI co-use","section":"what_is_unknown","tier":"human","source_ids":["s5"],"source_status":"sourced","why_material":"Clarifies evidence gap","evidence_basis":"derived_inference","weight":0.8,"status":"active","stance_scores":{"neutral":0,"pro":0,"adversary":0},"extra":{},"posted_by":{"actor":"grok/4.3-populate","channel":"populate-repair","ts":"2026-06-29T11:09:22.940Z","model":"grok/grok-4.3","rationale":"backfilled by ledger repair"},"who_claims":"grok/4.3-populate","slot":"what_is_unknown","source_role":"core_stack_evidence"},{"id":"c4","text":"2024 rat study showing Semax reverses anhedonia (emotional blunting-like symptom) and increases BDNF in chronic stress model;

A 2019 review noted patients reporting dulled emotions despite reduced pain (human). A 2023 Cambridge University study in healthy volunteers found escitalopram reduced reinforcement learning sensitivity compared to placebo (human).\n\nSSRIs primarily suppress symptoms via serotonergic modulation without directly addressing underlying neuroplasticity deficits (mechanistic).\n\n## BDNF and Neuroplasticity\n\nBDNF drives synaptic plasticity, neuron survival, and connection formation (mechanistic). Reduced BDNF is linked to mood and cognitive issues in preclinical models.\n\n## Semax and BDNF Upregulation\n\n### Preclinical Evidence (Rat and Cell Studies)\n\nSemax, an ACTH(4-10) analog, increases BDNF protein levels and mRNA expression in rat hippocampus and basal forebrain (preclinical). A 2006 study reported a single intranasal dose (50 μg/kg) produced a maximal 1.4-fold BDNF protein increase and 3-fold exon III BDNF mRNA increase in rat hippocampus, with elevated trkB phosphorylation (preclinical). Another 2006 study showed Semax binding and BDNF elevation specifically in rat basal forebrain astrocytes (preclinical). Cell culture work indicated up to 8-fold BDNF mRNA increase in glial cells (preclinical).\n\nThese effects occur rapidly (within hours) and are region-specific (preclinical).\n\n### Human Data\n\nLimited human trials exist for Semax in cognitive or neurological contexts, such as pilot fMRI changes in healthy subjects or stroke recovery, but none directly examine BDNF levels, emotional blunting, or SSRI co-administration (human; limited data). No human trials address Semax for SSRI-related issues.\n\n### User Reports\n\nNo verified large-scale user data or controlled reports were identified in searches.\n\n## Mapping Semax to Neuroplasticity Support\n\nSemax's BDNF upregulation represents a mechanistic pathway potentially supporting neuroplasticity and connection formation, distinct from symptom suppression (mechanistic; preclinical). This contrasts with SSRI action focused on serotonergic modulation (mechanistic). Novelty of this specific mapping is high due to absence of direct comparative human data.\n\nAll claims graded by available evidence tiers. No human data exist for Semax in SSRI emotional blunting contexts.","claims":[{"id":"c1","text":"SSRIs associated with emotional blunting and reduced reinforcement sensitivity in

A 2019 review noted patients reporting dulled emotions despite reduced pain (human). A 2023 Cambridge University study in healthy volunteers found escitalopram reduced reinforcement learning sensitivity compared to placebo (human).\\n\\nSSRIs primarily suppress symptoms via serotonergic modulation without directly addressing underlying neuroplasticity deficits (mechanistic).\\n\\n## BDNF and Neuroplasticity\\n\\nBDNF drives synaptic plasticity, neuron survival, and connection formation (mechanistic). Reduced BDNF is linked to mood and cognitive issues in preclinical models.\\n\\n## Semax and BDNF Upregulation\\n\\n### Preclinical Evidence (Rat and Cell Studies)\\n\\nSemax, an ACTH(4-10) analog, increases BDNF protein levels and mRNA expression in rat hippocampus and basal forebrain (preclinical). A 2006 study reported a single intranasal dose (50 μg/kg) produced a maximal 1.4-fold BDNF protein increase and 3-fold exon III BDNF mRNA increase in rat hippocampus, with elevated trkB phosphorylation (preclinical). Another 2006 study showed Semax binding and BDNF elevation specifically in rat basal forebrain astrocytes (preclinical). Cell culture work indicated up to 8-fold BDNF mRNA increase in glial cells (preclinical).\\n\\nThese effects occur rapidly (within hours) and are region-specific (preclinical).\\n\\n### Human Data\\n\\nLimited human trials exist for Semax in cognitive or neurological contexts, such as pilot fMRI changes in healthy subjects or stroke recovery, but none directly examine BDNF levels, emotional blunting, or SSRI co-administration (human; limited data). No human trials address Semax for SSRI-related issues.\\n\\n### User Reports\\n\\nNo verified large-scale user data or controlled reports wer","tokens_in":0,"tokens_out":0,"cost":0,"prev":"genesis","hash":"d6d739612e55b5e813502a75af3798e4d6f8bef0abe30b6df157fdaa9048caa3"},{"ts":"2026-06-29T11:08:15.020Z","model":"grok-4.3","action":"sources","prompt":"","input":"semax-ssri-emotional-blunting","response":"3 source(s) added","tokens_in":0,"tokens_out":0,"cost":0,"prev":"d6d739612e55b5e813502a75af3798e4d6f8bef0abe30b6df157fdaa9048caa3","hash":"ea3bbef78f8da5fb35e5d13e1759180e2f8e47b18565ebd3f0a98547364367a1"},{"ts":"2026-06-29T11:08:33.669Z","model":"grok-4.3","action":"sources","prompt":"","input":"semax-ssri-emotional-blunting","response":"2 source(s) added","tokens_in":0,"tokens_out":0,"cost":0,"prev":"ea3bbef78f8da5fb35e5d13e1759180e2f8e47b18565ebd3f0a98547364367a1","hash":"574c98ea6c65665571e23122ffc9473e24542a2afb582718a538c48098492101"},{"ts":"2026-06-29T11:08:59.541Z","model":"grok-4.3","action":"sources","prompt":"","input":"semax-ssri-emotional-blunting","response":"3 source(s) added","tokens_in":0,"tokens_out":0,"cost":0,"prev":"574c98ea6c65665571e23122ffc9473e24542a2afb582718a538c48098492101","hash":"10187ed4e4b9b68aafe19befe1fe291d8dbf79c858d206128132c6b6c1773553"},{"ts":"2026-06-29T11:09:22.724Z","model":"grok-4.3","action":"sources","prompt":"","input":"semax-ssri-emotional-blunting","response":"3 source(s) added","tokens_in":0,"tokens_out":0,"cost":0,"prev":"10187ed4e4b9b68aafe19befe1fe291d8dbf79c858d206128132c6b6c1773553","hash":"218f954d53d0faece974f4cef39d903e0225ef2d4916202c9c237db5eacfa34c"},{"ts":"2026-06-29T11:10:17.948Z","model":"grok-4.3","action":"sources","prompt":"","input":"semax-ssri-emotional-blunting","response":"2 source(s) added","tokens_in":0,"tokens_out":0,"cost":0,"prev":"218f954d53d0faece974f4cef39d903e0225ef2d4916202c9c237db5eacfa34c","hash":"7b66ea3bd2b03f85e0efc1b38f6e49bb0e23a1026fd8219b1889d3e07bfefe47"},{"ts":"2026-06-29T11:10:37.065Z","model":"grok-4.3","action":"sources","prompt":"","input":"semax-ssri-emotional-blunting","response":"5 source(s) added","tokens_in":0,"tokens_out":0,"cost":0,"prev":"7b66ea3bd2b03f85e0efc1b38f6e49bb0e23a1026fd8219b1889d3e07bfefe47","hash":"f35d09f970732389adc633dcd89585ed8149df93fa78d43b8869b539de63efde"},{"ts":"2026-06-29T11:11:06.639Z","model":"grok-4.3","action":"sources","prompt":"","input":"semax-ssri-emotional-blunting","response":"3 source(s) added","tokens_in":0,"tokens_out":0,"cost":0,"prev":"f35d09f970732389adc633dcd89585ed8149df93fa78d43b8869b539de63efde","hash":"6861af440528ce79db8e1f5f336e1aea13807a1b8d94e46f2812316aacbfafae"},{"ts":"2026-06-29T12:49:02.275Z","model":"system/audit-repair","action":"repair","prompt":"","input":"semax-ssri-emotional-blunting","response":"{\"materialized\":0,\"before\":[\"missing constitution slots: what_it_is, what_is_known, what_is_unknown, limitations, disclaimer\"],\"after\":[\"missing constitution slots: what_it_is, what_is_known, what_is_unknown, limitations, disclaimer\"]}","tokens_in":0,"tokens_out":0,"cost":0,"prev":"6861af440528ce79db8e1f5f336e1aea13807a1b8d94e46f2812316aacbfafae","hash":"3c3f0fa8243917ecebfdeb49dbc01e9c81c415421e4789163c401bf64cfcb434"},{"ts":"2026-06-29T12:49:02.864Z","model":"system/audit-repair","action":"claim","prompt":"","input":"semax-ssri-emotional-blunting c25","response":"Semax for SSRI Emotional Blunting is catalogued in this miscsubjects ledger as a tier-honest evidence graph (claims + hash-chained sources).
