What is BPC-157?
Short answer
BPC-157 is a synthetic chain of 15 amino acids derived from a protein found in human gastric juice. It has been studied mainly in animal models of tendon, ligament, muscle and gut repair, with no large human trials published. In the US it is available only as a compounded medication prescribed by a licensed provider, and compounded medications are not FDA-approved. It is prohibited in sport.

Where does BPC-157 come from?
BPC-157 is a fragment of a larger protein that researchers isolated from human gastric juice and named Body Protection Compound. The 15-amino-acid fragment was synthesized so it could be studied on its own, and it turned out to be stable in gastric acid, which is unusual for a peptide and is why early research centered on the stomach and gut.
The compound is entirely synthetic as prescribed: a compounding pharmacy does not extract it from tissue, it assembles the sequence. That matters for how it is regulated, because a synthetic peptide with no approved product behind it can only reach a patient through a prescription for a compounded medication.
What has BPC-157 been studied for?
BPC-157 research is dominated by animal models, mostly in rats, and by review articles that summarize them. The reviews describe work on tendon, ligament, muscle and bone healing, on gut lesions and fistulas, and on the formation of new blood vessels that carry nutrients into injured tissue. Several describe interactions with the nitric oxide system and with growth-factor signaling.
What the literature does not contain is a published, large, randomized human trial. The honest reading is interest, not proof: the preclinical signal is consistent across many animal studies, and human data remains thin. Any page that tells you what BPC-157 will do for you is going beyond the evidence.
| Area | Type of evidence | What the reviews describe |
|---|---|---|
| Tendon, ligament, muscle | Animal models | Faster repair and new blood vessel formation in injury models |
| Gut lining and fistulas | Animal models | Healing of experimental lesions |
| Mechanism | Animal and cell studies | Nitric oxide pathway and growth-factor interactions |
| Humans | No large trials published | Case reports and small series only |

How is BPC-157 prescribed?
BPC-157 is prescribed in the US as a compounded medication: a licensed provider writes a prescription for an individual patient and a licensed 503A pharmacy prepares it. Through Peptides.build it is prescribed as a subcutaneous injection and ships already reconstituted, with the concentration printed on the pharmacy label, so patients do not mix vials or add water.
It also appears inside the Wolverine Stack, which pairs BPC-157 with TB-500 in one vial, and inside the Glow and KLOW stacks. Whether the single compound or a stack is appropriate is a decision the provider makes during intake; dosing is set by the provider and is never published on this site.
Is BPC-157 FDA-approved or allowed in sport?
BPC-157 is not FDA-approved for any use. When it is prescribed, it is a compounded medication, and compounded medications are not reviewed or approved by the FDA the way mass-manufactured drugs are. That status is the same for every peptide in this catalog and is stated on every protocol page.
In sport, BPC-157 is prohibited at all times. The World Anti-Doping Agency lists it among non-approved substances, so drug-tested athletes should check with their governing body before using it.
How are BPC-157 doses measured?
BPC-157 prescriptions are written in micrograms, and the amount drawn depends on the concentration of the vial. A pre-mixed pharmacy vial prints that concentration in mg/mL; a powder vial gets its concentration from the water added. The free BPC-157 calculator on this site converts a prescribed dose and a label strength into units on a U-100 insulin syringe, and includes a mode for the BPC-157 and TB-500 blend. It performs arithmetic only and does not recommend a dose.
Prescribed BPC-157 vs research peptides: what is different?
Prescribed BPC-157 is not a research chemical. It is a prescription medication: a licensed US provider reviews your intake first, and a licensed 503A pharmacy compounds it for you by name. Vials sold online as “research use only” skip both steps. What you pay for here is that review, a pharmacy you can name, and a label that says what is in the vial.
A research seller’s certificate of analysis is a document the seller controls: it chooses the lab and the sample, and a PDF can be reused, edited or re-dated. No regulator checks it.
| Point | Prescribed through Peptides.build | Research use only |
|---|---|---|
| Access | Online intake reviewed by a licensed US provider; prescribed only when appropriate. | No prescription and no clinical review of whether it suits you. |
| How it's labeled | A prescription medication compounded for you by name. | Commonly sold labeled “research use only, not for human consumption.” |
| Who prepares it | A licensed 503A US compounding pharmacy under state and federal oversight. | Unregulated suppliers, often with no verifiable chain of custody. |
| Testing | Third-party tested. | Certificates of analysis are self-reported when provided at all. |
| Purity and identity | Prepared to a prescription for a specific patient. | Purity, strength, and even identity are unverified by any independent party. |
This compares two care models, not two products. Compounded medications are not FDA-approved, and we do not claim otherwise. What a prescription adds is a licensed provider deciding whether a protocol is appropriate for you and a licensed pharmacy preparing it. Read the full guide to research vs prescription peptides.
BPC-157 FAQ
Is BPC-157 a steroid or a hormone?
No. BPC-157 is a peptide, a short chain of amino acids. It is not an anabolic steroid and not a hormone, although animal studies describe interactions with growth-factor and nitric oxide signaling.
Has BPC-157 been tested in humans?
Most published BPC-157 research is in animal models and review articles. Large human clinical trials have not been published, which a prescribing provider will discuss with you.
Is BPC-157 legal in the United States?
BPC-157 is not FDA-approved for any use. In the US it reaches patients only as a compounded medication prescribed by a licensed provider and prepared by a licensed 503A pharmacy; compounded medications are not FDA-approved.
Is BPC-157 banned in sport?
Yes. The World Anti-Doping Agency lists BPC-157 among prohibited non-approved substances, banned at all times. Drug-tested athletes should check with their governing body.
What is the difference between BPC-157 and the Wolverine Stack?
The Wolverine Stack is BPC-157 plus TB-500, a synthetic fragment of thymosin beta-4, in one vial. Both compounds have preclinical repair research behind them; whether one or both is appropriate is a provider decision.
BPC-157 through Peptides.build
A licensed US provider reviews a short online intake and decides whether a protocol is appropriate. A US 503A pharmacy prepares it already reconstituted, labels the concentration and ships it cold-chain. Dosing is set by the provider and is not published on this site.
