📑 Table of Contents
What is BPC-157?
BPC-157 (Body Protection Compound-157) is a synthetic peptide consisting of 15 amino acids. It's derived from a protective protein found in human gastric juice. The compound was first identified by researchers studying the healing properties of gastric secretions.
In research settings, BPC-157 has been studied for its potential effects on:
Areas of Research
- Tendon, ligament, and muscle healing
- Gut health and integrity
- Wound healing and tissue repair
- Bone and joint recovery
- Inflammation modulation
What Does the Research Say?
Most BPC-157 research has been conducted in animal models (primarily rats) and in vitro (cell cultures). As of 2026, there are limited published human clinical trials.
Animal Studies (Promising)
Rat studies have shown accelerated healing of various tissues including tendons, ligaments, muscles, and the GI tract. The peptide appears to promote angiogenesis (new blood vessel formation) and increase growth factor expression. For safety considerations, see our comprehensive BPC-157 safety guide.
Human Studies (Limited)
Few human trials have been completed. Most human evidence is anecdotal, from biohackers and athletes who report positive outcomes. More rigorous clinical trials are needed.

Dosing Protocols
The following dosing information is based on anecdotal reports and extrapolation from animal studies. There is no established human dosing protocol.
| Protocol | Dose | Frequency | Duration |
|---|---|---|---|
| Standard | 250-500 mcg | 1-2x daily | 4-12 weeks |
| Aggressive (injury) | 500-750 mcg | 2x daily | 4-8 weeks |
| Maintenance | 250 mcg | Once daily | Ongoing |
Injection Methods
- Subcutaneous (subQ): Most common. Inject into belly fat or near injury site.
- Intramuscular (IM): Some prefer this near injury sites.
- Oral: Less common; some report GI benefits with oral administration.
How to Reconstitute BPC-157
BPC-157 typically comes as a lyophilized (freeze-dried) powder in vials of 5mg or 10mg.
Standard Reconstitution (5mg vial)
- Add 2mL bacteriostatic water → 250 mcg per 0.1mL (10 units)
- Add 2.5mL bacteriostatic water → 200 mcg per 0.1mL (10 units)
- Add 1mL bacteriostatic water → 500 mcg per 0.1mL (10 units)
🧮 Reconstitution & Dosing
See the step-by-step reconstitution math (concentration and injection volume) in the guide below.
See Reconstitution Steps ↓Storage Guidelines
| Form | Storage | Shelf Life |
|---|---|---|
| Lyophilized (powder) | Room temp or refrigerated | 2+ years |
| Reconstituted | Refrigerated (36-46°F) | 4-6 weeks |
| Reconstituted | Frozen | 6+ months |
Tips: Keep away from light. Don't shake reconstituted vials. Use bacteriostatic water (not sterile water) for longer shelf life.
Common Stacks
🐺 "Wolverine Stack"
BPC-157 + TB-500 — Popular combination for injury recovery
- BPC-157: 250-500 mcg daily
- TB-500: 2-2.5mg twice weekly (loading), then weekly
GI Health Stack
BPC-157 + L-Glutamine — For gut healing protocols
- BPC-157: 250-500 mcg daily (oral or subQ)
- L-Glutamine: 5-10g daily
Potential Side Effects
BPC-157 is generally reported to be well-tolerated in anecdotal reports. However, potential side effects may include:
- Nausea (especially with higher doses)
- Dizziness
- Headache
- Injection site reactions
- Fatigue
Frequently Asked Questions
How long until I see results?
Anecdotal reports suggest noticeable effects within 1-2 weeks for injuries, though some report improvements within days. Full healing protocols typically run 4-12 weeks.
Can I inject near the injury site?
Yes, many users inject subcutaneously or intramuscularly near the affected area, though systemic (belly fat) injections are also reported as effective.
Is BPC-157 legal?
In most countries, BPC-157 exists in a grey area — legal to purchase for "research purposes" but not approved for human consumption. Laws vary by jurisdiction. It's banned by WADA for competitive athletes.
Where do people source BPC-157?
Research peptide vendors sell BPC-157 labeled "for research purposes only." Quality varies significantly. Many users look for vendors with third-party testing.
