BPC-157

Research compound. This is not a dietary supplement. Unless it is identified as an approved prescription drug, it is not approved by the FDA for human use. This page summarizes published research for education only; we do not sell it or link to sellers.

BPC-157. A synthetic pentadecapeptide derived from a protective protein in human gastric juice, studied across many tissue-repair models.

How it works. Believed to upregulate growth-factor receptors, modulate nitric oxide signaling, and promote angiogenesis at sites of tissue damage, accelerating repair across multiple tissue types.

What the research supports. 4 graded claims. Strongest: Reported acceleration of soft-tissue recovery (tendon, ligament, muscle) (preclinical).

Hormonal impact. Effects on Growth hormone / IGF-1, Cortisol, Serotonin (5-HT), Dopamine.

Side effects and interactions. 2 medication interactions listed. Serious: Unknown long-term human safety profile — no large clinical trials.

Stacking. Pairs well with TB-500, Collagen peptides. Avoid combining with Active malignancy.

Common forms. Available as Subcutaneous injection, Oral capsule (research), Nasal spray (compounded).

Community. Experiences from people who have tried BPC-157. Anecdotes are not medical advice.

What it is

BPC-157 is a 15-amino-acid sequence derived from a larger gastric protective protein. In preclinical studies it accelerates healing of tendon, ligament, muscle, bone, gut, and nerve tissue.

Also called

Body Protection Compound-157Pentadecapeptide BPC 157

How it works

Believed to upregulate growth-factor receptors, modulate nitric oxide signaling, and promote angiogenesis at sites of tissue damage, accelerating repair across multiple tissue types.

Pathways

  • VEGFR2 – Akt – eNOS signaling (angiogenesis)
  • FAK – paxillin (cell migration and adhesion)
  • Dopaminergic, serotonergic, and GABAergic modulation
  • Nitric oxide system stabilization

Effects

  • ↑Angiogenesis at injury sites increases
  • +Tendon, ligament, and gut lining repair supports
  • ↓Local inflammatory cytokine load decreases
  • +Gastrointestinal mucosal integrity optimizes

What the research supports

Reported acceleration of soft-tissue recovery (tendon, ligament, muscle)preclinical
Anecdotal improvement of gut symptoms in IBD-like presentationspreclinical
Apparent reduction of joint pain after overuse injuriespreclinical
Possible neuroprotective and mood-stabilizing effectspreclinical

Strong: consistent results across large trials or meta-analyses. Moderate: several trials, mostly positive. Limited: small or mixed studies. Preclinical: animal or cell research only.

Hormonal impact

=Growth hormone / IGF-1stabilizes
~Cortisolmodulates
~Serotonin (5-HT)modulates
=Dopaminestabilizes

Side effects & interactions

Common side effects

  • Injection-site irritation
  • Mild head pressure or fatigue
  • Transient dizziness

Serious

  • Unknown long-term human safety profile — no large clinical trials

Medication interactions

NSAIDsminor

Often discussed as a 'rescue' for NSAID-induced gut damage in animal models.

Anticoagulantsmoderate

Theoretical bleeding/clotting interaction via angiogenic pathways.

Check any supplement–medication combination with your pharmacist before starting.

Combines with

Pairs well

  • TB-500Frequently stacked in research protocols for additive tissue-repair effects.
  • Collagen peptidesProvides amino-acid substrate for new connective tissue.

Avoid combining

  • Active malignancyAngiogenic activity is theoretically undesirable when tumors are present.

Common forms

  • Subcutaneous injection
  • Oral capsule (research)
  • Nasal spray (compounded)
