Say the asymmetry out loud before anything else, because most pages comparing these two hide it.

**Ibuprofen has been tested in people, at scale, and it works.** A Cochrane overview pulled together 39 systematic reviews covering roughly 460 randomised trials and about 50,000 participants, all measuring one thing: how many people get at least half their pain taken away. Ibuprofen 400 mg came out at a number-needed-to-treat of 2.5 — treat five people, two get at least 50% pain relief who would not have got it from a dummy pill. Fast-acting ibuprofen 200 mg: 2.1. Ibuprofen 200 mg with paracetamol 500 mg: 1.6, one of the best numbers in the entire table.

[[embed:source:s23]]

**BPC-157 has never completed a randomised controlled trial in a human being for any injury.** Not for tendon, not for muscle, not for a disc, not for a joint. The evidence is rats, a small number of early-phase human safety studies on other conditions, and a large volume of self-reported experience.

[[embed:bpc-157]]

That is the honest starting position and it does not favour the peptide. If your only question is "will this reduce my pain in the next four hours," the answer is the drug with 50,000 participants behind it, and no amount of mechanism argument changes that.

Now the two things that make this a real question rather than a rout.

## For back pain specifically, the drug's own trials are unimpressive

The 50,000-participant number comes from post-surgical pain. Back pain is a different question and it has its own trials, and they are far less flattering.

**Acute low back pain.** Cochrane pooled 32 trials, 5,356 participants. Against placebo, anti-inflammatories reduced pain by **7.29 points on a 0–100 scale** (95% CI −10.98 to −3.61), moderate-quality evidence. Disability improved by 2.02 points on a 0–24 scale, high-quality evidence. The reviewers' own summary of that magnitude: "small and probably not clinically relevant." No difference between COX-2-selective and older ones. Almost half the studies were industry-funded.

[[embed:source:s21]]

**Chronic low back pain.** Cochrane, 13 trials. Against placebo, **3.30 points on the same 0–100 scale** (95% CI −5.33 to −1.27), low-quality evidence. Disability, 0.85 points on a 0–24 scale. And this line, which deserves to be read twice: when the reviewers restricted the analysis to trials at low risk of bias, the difference between the drug and placebo got *smaller*.

[[embed:source:s22]]

Set those numbers beside the one intervention with a genuinely large effect for the same condition: structured exercise, pooled across 249 randomised trials, produced a **15.2-point** pain reduction, which cleared the reviewers' pre-set threshold for a clinically important difference.

[[embed:source:s24]]

So the honest ranking for a back, on human trial evidence, is: exercise 15.2 points, anti-inflammatories 7.3 points for acute and 3.3 for chronic, BPC-157 untested. The drug beats the peptide because the peptide has nothing. It loses badly to walking and lifting.

## What each one actually does to the tissue

An anti-inflammatory blocks an enzyme called COX-2. COX-2 makes prostaglandins. Prostaglandins are what make an injury swell, throb and hurt. Block the enzyme, lose the prostaglandins, lose the pain. That is the whole drug.

The complication is that prostaglandins are not only a pain signal. They are also the opening instruction of tissue repair — the message that recruits repair cells to a damaged site and starts the rebuilding. One molecule, two jobs. The drug cannot separate them.

BPC-157 runs the opposite way. It is a short chain of fifteen amino acids based on a sequence found in human stomach juice, and in animals it raises VEGF, the signal that grows new blood vessels into damaged tissue, and drives connective-tissue cells to migrate into and repair an injury. It has no pain-blocking action of its own worth speaking of.

One suppresses the signal. The other is studied for accelerating what the signal is calling for. That is the actual axis of this comparison, and neither side of it is automatically the right answer — it depends entirely on what you are trying to buy.

## The case against months of anti-inflammatories is specific, numbered, and not about healing

Most arguments against these drugs are vague and moralising. The real case is none of those things. It is four separate, measured harms, three of which are not in serious dispute.

### The stomach

The largest analysis of individual patient data — 280 trials against placebo covering 124,513 participants, plus 474 head-to-head trials covering 229,296 — put numbers on it by drug. Upper gastrointestinal complications, meaning a perforation, obstruction or bleed:

| Drug | Increase in upper gut complications vs placebo |
|---|---|
| Naproxen | 4.22× |
| Ibuprofen | 3.97× |
| Diclofenac | 1.89× |
| COX-2-selective drugs (coxibs) | 1.81× |

[[embed:source:s18]]

Note what that table does to the popular story. Naproxen, the one usually recommended as the heart-safe choice, has the *worst* gut number in the set. There is no drug in that column that is free.

The head-to-head randomised trial confirms the direction. PRECISION randomised 24,081 patients with arthritis and raised heart risk to celecoxib, ibuprofen or naproxen for a mean of 20 months. Gastrointestinal events were significantly lower with celecoxib than with either naproxen (p=0.01) or ibuprofen (p=0.002).

[[embed:source:s19]]

### The heart

From the same 124,513-participant analysis:

| Drug | Major vascular events | Major coronary events |
|---|---|---|
| Coxibs | 1.37× | 1.76× |
| Diclofenac | 1.41× | 1.70× |
| Ibuprofen | 1.44× (not significant) | 2.22× |
| Naproxen | 0.93× (no increase) | — |

**Heart failure risk was roughly doubled by all of them.** In absolute terms: for every 1,000 people taking a coxib or diclofenac for a year, three extra major vascular events, one of them fatal.

[[embed:source:s18]]

That is the honest trade-off between the two tables. Naproxen is the kindest to your heart and the harshest on your stomach. Celecoxib is the reverse. There is no free option, and PRECISION found celecoxib was not worse than the other two on heart outcomes at moderate doses, which softened but did not erase the coxib concern.

[[embed:source:s19]]

### The kidneys

Forty studies covering 1,757,118 participants. Long-term use raised the odds of developing or worsening chronic kidney disease: pooled odds ratio 1.24, pooled hazard ratio 1.50. In people who already had kidney disease, the hazard ratio was 1.67.

[[embed:source:s20]]

In PRECISION, kidney events were significantly lower with celecoxib than with ibuprofen (p=0.004).

[[embed:source:s19]]

### The report pile at the regulator, and exactly what it is not

FDA's public adverse event system holds reports sent in voluntarily by patients, doctors and manufacturers. Queried on 4 August 2026, it holds **283,544 reports naming ibuprofen** and **165,063 naming naproxen**.

Say what those numbers are before reading them. They are counts of reports, not counts of people harmed. There is no denominator anywhere in the system — nobody knows how many people took either drug and reported nothing, and that missing number is the one an incidence rate would need. A report is not a finding that the drug caused the event. The same event can arrive more than once. Reporting rises when a drug is in the news. Nothing in this table is a rate, and it cannot be turned into one.

| Reported event | Reports naming ibuprofen | Reports naming naproxen |
|---|---|---|
| Acute kidney injury | 7,141 | 3,145 |
| Kidney failure | 4,216 | 2,562 |
| Bleeding in the gut | 2,689 | 1,486 |
| Heart attack | 1,781 | 1,770 |
| Stomach ulcer | 1,394 | 867 |
| Black stool from a gut bleed | 1,208 | 478 |
| Heart failure | 634 | 305 |
| Bleeding from the stomach lining | 622 | 489 |
| Ulcer in the first part of the small intestine | 614 | 359 |

[[embed:source:s42]]

Two things are worth taking from it. The kidney rows sit above the gut rows for both drugs, which is the opposite of the ordering most people carry in their heads, and it lines up with the direction of the 1,757,118-participant kidney analysis rather than contradicting it. And the single most reported term for both drugs is not a harm at all: **"drug ineffective" — 27,383 times for ibuprofen and 22,584 for naproxen.** Set that beside the Cochrane back-pain numbers at the top of this page and it is the same finding arriving from the other end of the evidence pyramid.

The controlled trials above give you rates. This gives you the shape of what lands when something goes wrong. Use it for the second and never for the first.

### Tendon and soft-tissue healing — the one that is genuinely contested

This is the argument most often made and least often made carefully. Here is what the evidence supports and where it stops.

**In animals it is consistent and specific.** In a rotator cuff repair model, both an older anti-inflammatory (indomethacin) and a COX-2-selective one (celecoxib) produced significantly weaker tendon-to-bone healing than untreated controls, out to eight weeks.

[[embed:source:s1]]

**The timing pattern is the strongest part of the case.** Give ibuprofen during the early repair window and tendon healing is measurably worse; give the same drug later and the effect fades. That is exactly the pattern you would predict if the drug is interrupting the initial repair instruction rather than merely masking pain.

[[embed:source:s3]]

**Bone shows it too.** Pooled animal data show these drugs measurably reduce the mechanical strength of healing fractures.

[[embed:source:s6]]

**The mechanism is not a coincidence.** Knock out COX-2 in mice and fractures heal badly. Restore the downstream prostaglandin signal and the healing is rescued. The enzyme the drug exists to block is the same enzyme repair runs on.

[[embed:source:s8]]

**It reaches human repair cells.** In a human study, infusing an anti-inflammatory locally during exercise abolished the normal rise in muscle satellite cells — the stem cells that rebuild muscle after loading.

[[embed:source:s7]]

**And now the counter-evidence, which is real.** A meta-analysis of human fracture outcomes that adjusted for confounders found **no significant increase in fracture non-union** among people taking these drugs.

[[embed:source:s5]]

**There is even a species-level reason it might not translate.** Human skeletal stem cells were directly compared with rodent ones and turned out to be substantially less dependent on COX-2 for their function.

[[embed:source:s4]]

So the fair verdict, stated as a rate rather than a mood: **animal healing impairment is consistently reproduced; human cellular repair signals are measurably blunted; human clinical healing outcomes show no proven harm.** Anyone claiming these drugs are proven to wreck human healing is overstating. Anyone claiming the concern is invented is ignoring the timing data and the knockout mice.

## Why this argument gets sharper when the injury is a disc

A herniated disc is the one case where the healing question is not theoretical, because the mechanism that removes a herniation *is* an inflammatory mechanism.

Displaced disc material meets blood supply and immune cells for the first time. Immune cells digest it, new blood vessels grow in to supply the operation, and about 70% of herniations reabsorb on their own within roughly six months.

[[embed:herniated-disc]]

Suppress that inflammation continuously and you are working against the clearance. This is not purely inference: corticosteroids inhibited resorption in preclinical work, and a clinical series that deliberately withheld anti-inflammatory drugs reported resorption in every patient.

[[embed:source:s17]]

That evidence is a case series, not a randomised trial, and it should be weighted as such. But it points the same direction as the tendon timing data, and it is the reason "a few days for a flare" and "eight months of daily tablets" are different decisions rather than different doses of the same decision.

The slower wear process behind many of these discs is a separate question with its own numbers, and it changes what a long course of anything is being asked to do:

[[embed:degenerative-disc-disease]]

## What BPC-157 actually has, listed without inflation

**In animals, the tendon results are the strongest thing it has.** A transected rat Achilles tendon treated with BPC-157 came back with greater load-to-failure and better collagen organisation than controls.

[[embed:source:s10]]

**The cellular behaviour matches.** Tendon cells showed better outgrowth, survival and migration — the three behaviours that define active repair rather than scarring over.

[[embed:source:s11]]

**And the mechanism is the mirror image of the drug's.** BPC-157 raises VEGF and drives new blood vessel growth into healing muscle and tendon — the same vascular pathway that COX-2 blockade suppresses.

[[embed:source:s12]]

**It protects against the drug's own gut damage, in rats.** Given alongside diclofenac, BPC-157 counteracted the gastrointestinal, liver and brain lesions the drug caused.

[[embed:source:s13]]

**The same protection held when adjuvant arthritis and drug-induced gut lesions were put on the animal together.**

[[embed:source:s14]]

**What none of that is:** a human result. Every item above is a rodent. There is no completed randomised controlled trial of BPC-157 in a human injury, no dose established for a human tendon, and no study of any kind against a human disc.

## Seven people on long-term anti-inflammatories, counted

**Seven first-person accounts from X, counted.** **Four of the seven reported a harm. One was warned off by a doctor before anything went wrong. One reported no problems over more than ten years. One is worried and getting tested, with no result back yet.**

Read this panel knowing exactly what is wrong with it: people post about the ulcer that sent them to hospital, not about the uneventful decade. The harm fraction here is not the population rate — the population rate is in the tables above, and it is a 4× relative increase on a small absolute base, not four in seven. This panel tells you what the harm looks like when it lands, not how often it lands.

**Reported a harm — 4 of 7.**

Kidney filtration flagged on bloodwork after years of six tablets a day:

[[embed:source:s25]]

A stomach bleed that lasted a year, and twelve years of avoiding the whole drug class afterwards:

[[embed:source:s26]]

Five tablets a day for five years for back pain, and a stomach that can no longer tolerate the drug at all:

[[embed:source:s27]]

An ulcer, black stool, and an emergency room:

[[embed:source:s28]]

**Warned off, no harm reported yet — 1 of 7.** Nearly two years of naproxen with a stomach-protecting drug alongside it, then a new doctor capping it at six months:

[[embed:source:s29]]

**No problems — 1 of 7.** Over ten years of use, including long continuous stretches, and no reported issue:

[[embed:source:s30]]

**Worried, no result yet — 1 of 7.** Years of heavy use, now getting kidney and liver function tested:

[[embed:source:s31]]

## Ten people on BPC-157, counted

**Ten first-person accounts from X**, all self-reported, none verified, none from a trial. **Six said it helped. One said it helped and raised the possibility of placebo himself. Two said it did not work. One reported no outcome either way. Nobody reported a serious harm, and the only physical complaint in the set was at an injection site.**

Two of the six positive accounts carry either a supplier link or a follow-me pitch attached to the post. That is not proof they are false, but it is a selection problem you should hold in mind while reading them.

**Said it helped — 6 of 10.**

A dried-out lower disc plus a year-old biceps tendon problem, six weeks of BPC-157 and TB-500 — tendon and shoulder resolved, disc improved but explicitly still needing physiotherapy:

[[embed:source:s32]]

Elbow tendon pain of months' standing, injected locally at the site:

[[embed:source:s33]]

A two-and-a-half-year knee injury the poster says nothing else had fixed:

[[embed:source:s34]]

Shoulder and joint pain on the BPC-157 plus TB-500 combination — note this post also links a supplier:

[[embed:source:s35]]

A rotator cuff for which surgery had been recommended, two eight-week cycles, surgery avoided — note this post ends in a follow-me pitch:

[[embed:source:s36]]

Two months, rotator cuff quiet during training, and heartburn gone as a side effect:

[[embed:source:s37]]

**Helped, but he flagged placebo himself — 1 of 10.** This is the most intellectually honest account in the set, and it is worth more than the enthusiastic ones:

[[embed:source:s38]]

**Said it did not work — 2 of 10.**

Ten years of on-and-off use and a flat verdict, including new tendon pain appearing while on it:

[[embed:source:s39]]

Eight weeks for a shoulder, judged not a success — with an interesting detail: stomach problems he had stopped noticing came back two weeks after stopping, which is the one place his account supports the gut-protective animal data even while rejecting the injury claim:

[[embed:source:s40]]

**No outcome reported — 1 of 10.** An injection-site problem from using too large a needle.

[[embed:source:s41]]

**What ten accounts can and cannot establish.** They cannot establish that it works — there is no control group, no blinding, no independent measurement, and a heavy bias toward people who bought the thing and want it to have worked. What they do establish, honestly: the reported experience is not uniformly positive, two of ten users describe no benefit at all, one of the enthusiasts volunteered placebo as an explanation unprompted, and nobody in this set reported a serious adverse event. Hold that against the 50,000-participant table at the top of this page and the size of the gap is the point.

## What is legal, which is a separate question from what works

**BPC-157 is not an approved drug anywhere.** Its regulatory position has moved recently, so the specific dates matter more than the summary. FDA placed it in Category 2 of the 503A bulk substances list in September 2023, barring pharmacy compounding. It was off all three categories by the 14 May 2026 revision after the nominations were withdrawn. In July 2026 FDA's own briefing document recommended against adding it; on 23 July 2026 the Pharmacy Compounding Advisory Committee voted 8–6 with one abstention to recommend adding it anyway, against FDA staff. It is not on the 503B outsourcing-facility list either.

**It is prohibited in sport at all times.** WADA's 2026 Prohibited List names BPC-157 explicitly under S0, non-approved substances — in and out of competition, not only on competition day. The US Department of Defense lists it on its Prohibited Dietary Supplement Ingredients List and states plainly that it is not a dietary ingredient but an unapproved drug, at any route.

**What it is sold as:** research chemical, research use only. That is a shipping label, not a legal category granting you permission to use it.

[[embed:bpc-157]]

**Ibuprofen and naproxen are over-the-counter medicines** with approved labels, approved dose ceilings, and pharmacist advice attached. That difference is not a footnote — it is the reason one of them has 50,000 participants of evidence behind it and the other does not.

## The decision table

| Your situation | What the evidence supports | What the evidence does not support | Legal position |
|---|---|---|---|
| Acute pain in the first few days, any injury | A short course of an anti-inflammatory. NNT 2.5 for ibuprofen 400 mg on at least 50% pain relief | That it speeds your healing, or that avoiding it makes you heal better | Over the counter |
| Acute back pain specifically | The same short course, with realistic expectations — 7.3 points on a 0–100 scale, which the reviewers called probably not clinically relevant | That it will do much. Movement outperforms it by roughly double | Over the counter |
| Chronic back pain, months in | Exercise. 15.2 points across 249 trials, against 3.3 points for the drug | Daily long-term anti-inflammatories as the plan. The effect shrinks in the least-biased trials and the harm accumulates | Over the counter, but this is the use with the harm tables attached |
| A herniated disc actively reabsorbing | Short courses to enable movement | Continuous suppression for months. Steroids inhibited resorption in preclinical work; one series avoiding these drugs saw resorption in every patient | Over the counter |
| You already have stomach disease or a bleed history | Avoiding the older drugs. Coxibs 1.81× vs ibuprofen 3.97× and naproxen 4.22× for upper gut complications | That any of them is gut-neutral | Prescription for coxibs in most places |
| You have heart disease or heart failure | Caution across the whole class. Heart failure risk roughly doubled by all of them; naproxen alone did not raise major vascular events | That the choice of drug removes the risk | Over the counter, which does not mean low-risk here |
| You have kidney disease | Avoiding long-term use. Hazard ratio 1.67 for progression in people who already have it | That short courses carry the same risk as chronic use | Over the counter |
| Tendon or soft-tissue injury where healing is the goal | Load management, progressive rehabilitation, and using pain relief sparingly in the first repair window | Either extreme. Animal harm is consistent; human non-union data shows none | Over the counter |
| You are considering BPC-157 for an injury | Nothing, in humans. Animal tendon repair is real and consistent; that is the entire honest case | Any human dose, any human timeline, any disc claim, any comparison of its effect size to the drug's | Not approved anywhere. Banned in sport at all times. Prohibited for US service members |
| You are a competing athlete | Whatever is on your sport's permitted list | Using BPC-157 under any framing, including "research use only" | WADA S0, strict liability, in and out of competition |

## The one-line version of each side

**For the drug:** it demonstrably relieves pain in humans at scale, it is legal, it is cheap, and the healing concern is unproven in human outcomes. Its costs are measured, drug-specific, and rise with duration rather than dose alone.

**For the peptide:** it has a coherent repair mechanism, consistent animal tendon results, and animal evidence that it protects the gut lining the drug damages. It has no human trial for any injury, no established dose, no legal approval, and a user-report base with two in ten reporting nothing at all.

Those two paragraphs are not equivalent and this page has not tried to make them equivalent. One is a medicine with a known effect size and a known bill. The other is an interesting hypothesis being taken by a lot of people ahead of its evidence.

*This page compares the state of the evidence. It is not medical advice and not a dosing recommendation. Do not stop a prescribed medicine on the basis of a web page. BPC-157 is sold for research use only, is not approved for human use in any jurisdiction, and is prohibited in sport at all times.*
