BPC-157, simplified.
Also called Body Protection Compound 157
Early researchThe most talked-about "healing peptide". It helped injuries heal faster in rats, but it has barely been tested in people.

What is it?
BPC-157 is a small piece of a protein found in stomach juice. Scientists think it helps tissue repair partly by growing new blood vessels and calming inflammation.

What studies show
- In animalsIn rats, it sped up healing of tendons, ligaments, muscles, bones and the gut lining.
- In animalsIt protected the stomach and intestines from damage in many animal studies.
- In peopleOnly a few tiny human reports exist, such as a small group with knee pain. None are large controlled trials.
What we don’t know yet
- Whether it works in people at all.
- Long-term safety. Because it helps grow blood vessels, some experts worry it could feed tumors.
Side effects and cautions
- Quality of online products varies a lot.
- Banned in sport by WADA.
Is it legal?
Not FDA-approved. In 2026, HHS announced plans to allow licensed compounding with a prescription, and an FDA advisory committee reviewed it in July 2026. Rules are still changing.

BPC-157: dosing research & protocol context
A plain-English guide to what a 10 mg vial means, how online protocols are described, and what the human evidence can—and cannot—tell us.

Reported week-by-week amounts
This table summarizes amounts reported by PeptideDosages.com for its BPC-157 10 mg vial example. They are not validated human doses, an accepted standard of care, or instructions for personal use.
| Period | Reported daily amount | Reported weekly total* |
|---|---|---|
| Weeks 1–2 | 200 mcg | 1.4 mg |
| Weeks 3–4 | 400 mcg | 2.8 mg |
| Weeks 5–8+ | 600 mcg | 4.2 mg |

Understanding Syringe Units
A U-100 syringe measures liquid volume, not milligrams or micrograms of a substance. The concentration of any solution depends on the verified amount of material and its final liquid volume.
Hypothetical concentration example
10 mg total peptide / 3 mL final solution volume = approximately 3.33 mg/mL
This describes concentration, not a safe dose. Syringe markings represent volume only; the peptide amount corresponding to a marking changes whenever the concentration changes.
| U-100 scale | Liquid volume |
|---|---|
| 10 units | 0.1 mL |
| 50 units | 0.5 mL |
| 100 units | 1 mL |
A calculated weekly peptide quantity does not determine an appropriate injection amount, number of injections, or spacing. BPC-157 has no established safe or effective human dosing regimen.
Consult your doctor before considering any peptide for personal use.
Understanding the dosage chart
Third-party protocol websites sometimes show week-by-week injection amounts and increasing schedules. These figures are experimental conventions, not approved or clinically validated instructions for BPC-157. There is no evidence-based human dose, titration schedule, injection frequency, or cycle length to recommend.
Vial strength versus dose
A vial labeled 10 mg describes its total nominal peptide content—not an amount to inject. The concentration of a prepared solution depends on the amount of diluent added. Without validated human dosing and product-specific quality controls, a vial label or syringe-unit chart cannot establish safe use.
Reconstitution and handling
Online guides discuss diluents, sterile handling, and refrigeration. Appropriate preparation and storage depend on the specific formulation, verified product quality, and professional instructions. There is no FDA-approved BPC-157 injectable product with a standardized preparation or storage label.
What the research actually shows
Most reported tissue-repair findings come from animal and laboratory studies. Human studies are sparse and do not establish whether BPC-157 improves recovery or what its long-term risks might be.
Safety considerations
- Identity, purity, sterility, and potency of unregulated products may be uncertain.
- Long-term effects and interactions in humans are not adequately characterized.
- Anecdotal reports and animal results should not be treated as clinical proof.
- Competitive athletes should check current anti-doping rules.
