BPC-157
Body Protection Compound-157
A 15-amino-acid synthetic peptide derived from a stable gastric protein. Widely used in practitioner protocols for tendon, ligament, and gut healing — with documented effects on angiogenesis, fibroblast proliferation, and growth-hormone receptor upregulation.
Quick reference
How BPC-157 works
BPC-157 modulates the VEGF / nitric-oxide pathway to drive angiogenesis (new blood-vessel formation) at injury sites. This dramatically improves perfusion to damaged connective tissue — the rate-limiting factor in most tendon and ligament recovery.
Secondary mechanisms include growth-hormone receptor upregulation, increased fibroblast migration, and modulation of pro-inflammatory cytokines (IL-6, TNF-α). Practitioner reports also describe improved gut barrier function in IBD-adjacent contexts, consistent with the peptide's gastric-protein origin.
In the DoseCraft framework, BPC-157 directly targets two of the Three Root Causes: Inflammation (cytokine modulation) and ATP Shortage (improved tissue perfusion → mitochondrial substrate delivery).
Reconstitution math
- Remove the flip-off cap from the 5 mg vial. Wipe the rubber stopper with an alcohol pad.
- Draw 2 mL of bacteriostatic water into a sterile syringe.
- Inject the bac water slowly down the inside wall of the vial — never directly onto the powder. Pressurized impact destroys the peptide.
- Swirl gently for 10–15 seconds. Do not shake.
- Refrigerate. Stable approximately 4 weeks at 2–8°C.
Dose math
5 mg vial + 2 mL bac water → 2,500 mcg per mL.
On a 100-unit insulin syringe (1 IU = 0.01 mL):
- • 10 IU = 250 mcg
- • 20 IU = 500 mcg
- • 40 IU = 1,000 mcg (1 mg)
Synergy stack
BPC-157 + TB-500 — the gold-standard recovery stack
BPC-157 initiates repair via VEGF and nitric oxide modulation. TB-500 (Thymosin Beta-4) sustains and guides it via actin binding and cell migration. The combination is well-documented in practitioner protocols for ACL recovery, rotator cuff repair, and chronic tendinopathy.
TB-500 loading
2.5–5 mg subQ every 3–4 days × 4–6 weeks
TB-500 maintenance
2.5 mg weekly until full recovery
Safety + side-effect profile
Reported side effects are generally mild and rare in the literature. Most-cited:
Not documented: hepatotoxicity, hormonal disruption, or significant cardiovascular changes at standard doses. Contraindications: pregnancy, lactation, active cancer therapy. Stop and consult a healthcare provider if you notice sustained heart-rate changes, unusual swelling, or persistent injection-site reactions.
Interaction notes: generally well-tolerated in stacks. Avoid combining with experimental BPC analogs (BPC-Arg, BPC-Lys) — practitioner consensus is to keep BPC-157 as the single Body Protection Compound in any given protocol.
- • Localized injection-site irritation (typically resolves in 24–48 hours)
- • Transient mild nausea, especially during loading phase
- • Occasional fatigue in the first 3–5 days
Frequently asked
What is BPC-157?
BPC-157 (Body Protection Compound-157) is a synthetic 15-amino-acid peptide derived from a stable gastric protein. It is widely used in research and practitioner protocols for tendon, ligament, and gut healing, with documented effects on angiogenesis, fibroblast proliferation, and growth-hormone receptor upregulation.
What is the typical BPC-157 dose?
Canonical foundational protocol: 500 mcg–1 mg subcutaneous daily (1 mg/day = the daily-forever baseline used in the Top 4 longevity stack). For acute injury, run 1 mg/day injected at the injury site, continuously, until repair plateaus. Cycle: 8–12 weeks on / 2–4 weeks off for extended/maintenance use; no cycle required for acute injury. Older community protocols sometimes describe 250–500 mcg 2× daily — that is drift from the canonical chapter; the consolidated baseline is 1 mg once daily.
How do I reconstitute BPC-157?
For a 5 mg vial: add 2 mL bacteriostatic water → final concentration 2,500 mcg/mL. On a 100-unit insulin syringe, 20 IU = 500 mcg, 10 IU = 250 mcg. Refrigerate after reconstitution; stable approximately 4 weeks. Inject the bac water slowly down the vial wall — never directly onto the lyophilized powder.
What's the best BPC-157 stack?
BPC-157 + TB-500 is the gold-standard recovery stack. TB-500 at 2.5–5 mg subcutaneous every 3–4 days for 4–6 weeks (loading), then 2.5 mg weekly. BPC-157 initiates repair via VEGF + nitric oxide modulation; TB-500 sustains and guides cell migration via actin binding.
Are there BPC-157 side effects?
Reported side effects are generally mild and rare in the literature: localized injection-site irritation, transient nausea, occasional fatigue. No documented hepatotoxicity or hormonal disruption at standard doses. Pregnancy/lactation contraindicated. Stop and consult a healthcare provider if you notice sustained heart-rate changes or unusual swelling.
Is oral BPC-157 effective?
No. Gastric enzymes destroy oral BPC-157 before it reaches systemic circulation. Subcutaneous injection is the only effective route for systemic healing. Some practitioners use oral preparations for gut-specific effects (e.g., IBD flares) where local action matters more than systemic absorption.
How long does BPC-157 take to work?
Soft-tissue patients typically report initial reduction in pain and inflammation within 7–14 days. Functional recovery (range of motion, load tolerance) usually shows by week 3–4. Full tendon-to-bone integration in chronic injuries can take the full 6–8 week protocol plus follow-up rehabilitation.
Should I cycle BPC-157?
Yes. Standard cycling: 4–6 weeks on, 4 weeks off. Continuous use beyond 8 weeks is not better-supported in the literature than cycled use, and cycling allows endogenous tissue-repair pathways to remain responsive. For chronic injuries, 2–3 cycles per year is typical.
