That crawling is what the vial is bought for, and it is the one job the seven amino acids sold as TB-500 were cut out to do: in 2003 a group cut the 43-amino-acid protein apart looking for the smallest piece that still grew new blood vessels and found exactly those seven, active at about 50 nanomolar, with anything shorter dead. In animals, the full-length protein improved repair in tendon, heart and skin; the strongest single result behind the fragment itself is one rat Achilles study with eight animals in the arm, where the new collagen was laid down parallel rather than crossways. In people, the number ever given the seven-amino-acid fragment in a study, by any route, is nought — no dose, no measured blood level, no side-effect rate. The controlled human evidence belongs to the parent protein given as eye drops or a skin gel: three completed dry-eye trials totalling 1,618 people, a nine-person dry-eye trial, an 18-person trial in a nerve-damaged cornea, and two 72-person skin-ulcer trials.\n\n**What the evidence supports doing.** Nothing, with the molecule that is actually in the vial. The single time anyone tested TB-500 itself in a dish, it closed no wound at all, and FDA has written down that capping the front end \"irreversibly alters their charge, hydrophobicity, and size\" so results from the uncapped seven amino acids cannot be carried across to it. Every transfer of evidence from the parent protein to the fragment is an assumption. If the crawling mechanism is what is wanted, the compound with an animal record in an injured animal — many models, dose-response, reproduced routes — is BPC-157, and the two are proposed to compound because BPC-157 grows the vessels while this is proposed to move the cells down them. No study in any species has given the pair together.\n\n**Against what a doctor prescribes for the same problem.** An anti-inflammatory reduces the pain by suppressing the process that repairs the tissue, and the tissue comes back weaker for it. The relief is real — ibuprofen 400 mg, number-needed-to-treat 2.5 for at least half the pain gone, across roughly 460 randomised trials and about 50,000 participants. The structural cost is measured too: in rats these drugs significantly lowered the maximum pull-out strength and the stiffness of a repaired tendon at its bone anchor, at every dosing window anyone has tested — the first five days, days 6 to 14, and days 11 to 20 after a repair. A steroid injection does not rebuild anything at all; what it buys is deferral of a surgical decision. Yearly bill on top: upper gut complications 3.97× on ibuprofen and 4.22× on naproxen, heart failure risk roughly doubled across the class. Held to one standard, neither side has a finished controlled trial showing it rebuilds a torn tissue in a person. The difference is that the drug has been measured making the healed join weaker, while the seven amino acids in this vial have not been measured doing anything to a person at all — no trial, no dose, no effect size, and no counted record at a known exposure, because nobody knows which molecule was in the vial.\n\nHere is the rest of the evidence state, and it decides how to read everything after it. Randomised trials of the seven-amino-acid fragment sold as TB-500: none completed, none running, none finished and unpublished. The number of people who have ever been given that fragment in a study, by any route, is nought, so there is no established dose for it, no measured blood level in a person, and no side-effect rate from a trial. One record on ClinicalTrials.gov names TB-500 — NCT07487363, first posted March 2026 — and its own public summary opens by saying it is a fictional example of a registry-style record.
