BPC-157

Mechanism

BPC-157 is a 15-amino-acid fragment derived from a gastric protective protein. It upregulates VEGFR2 signaling, driving angiogenesis at sites of soft-tissue injury, and modulates nitric oxide synthesis — the combination accelerates tendon, ligament, and gut mucosal repair. Unlike growth hormone pathway peptides, it works locally more than systemically, which is why injection proximal to the injury outperforms a single remote subq dose for orthopedic use.

It also has documented gut-protective effects (NSAID lesions, IBD-adjacent inflammation) and preserves vascular integrity under stress in animal models.

Typical protocol

• Starter: 250 mcg SC once daily, injected as close to the injury site as practical. Run 4 weeks on / 2 weeks off.
• Advanced: 500 mcg SC split AM/PM, local to the injury, for 4–6 weeks. Stack with TB-500 for tendon/ligament cases.
• Cycle length: avoid continuous use beyond 8 weeks. The tissue-healing window diminishes once the initial repair cascade resolves.
• Reconstitution: 2 mL BAC water into a 5 mg vial → 2.5 mg/mL. 10 IU on a U-100 insulin syringe = 250 mcg.

Who it's for

Recovery goal, hands down. Soft-tissue injuries (tendonitis, partial tears, post-surgical rehab), chronic joint issues, and gut-related inflammation. Not a muscle-building peptide, not a fat-loss peptide — don't force it into those roles.

Stacks well with

• tb 500 5mg — synergistic soft-tissue repair; BPC drives angiogenesis, TB-500 drives actin remodelling and cell migration.
• ghk cu 50mg — complementary collagen remodelling for dermal and joint matrix.
• beauty stack bpc tb500 ghk — pre-bundled BPC + TB-500 + GHK-Cu for combined recovery and connective-tissue work.

Watch-outs

• Will mask tendon and ligament pain. Keep training load honest or you'll re-injure once the signal is gone.
• Little evidence for acute fracture recovery — better for soft tissue than bone.
• Oral BPC exists in the literature but SC/IM is what actually works at these doses.
