Mechanism

Oral-stable BPC-157, typically formulated as the arginate salt, retains the same mechanism as standard BPC-157 — promoting angiogenesis via VEGFR2/PI3K/Akt/eNOS and Src-Caveolin-1-eNOS pathways, enhancing nitric oxide production, and stimulating tendon fibroblast growth and collagen formation. The arginate salt provides a protective buffer against gastric acid degradation, maintaining peptide integrity across a wider pH range. BPC-157 demonstrates remarkable native stability in human gastric juice (24+ hours), and the arginate form reportedly achieves 7-fold greater oral bioavailability compared to the acetate salt in preclinical studies.

Humanin

Peptides

Mechanism

Humanin is a 24-amino acid mitochondrial-derived peptide encoded by the 16S rRNA gene of mitochondrial DNA. It binds IGFBP-3 with high affinity (via Phe-6), interfering with IGFBP-3 binding to importin-beta and suppressing IGFBP-3-mediated apoptosis. It also inhibits the pro-apoptotic protein Bax (Bcl-2 family), preventing mitochondrial outer membrane permeabilization and intrinsic apoptosis. Humanin and IGFBP-3 synergistically protect neurons from amyloid-beta-induced apoptosis, and it activates the STAT3 and ERK1/2 pathways for cytoprotection.

Standard Dosing

Research indicates dosing remains experimental. Animal studies use 1-10 mcg/day equivalents. Human protocols are not established.

Timing

No established timing protocol. Morning dosing suggested for neuroprotective applications.

Cycle Duration

Experimental — no established cycle lengths.

Side Effects

  • Limited data on side effects in humans
  • Theoretical: interference with normal apoptotic processes

Contraindications

  • Active cancer (anti-apoptotic effects could support tumor survival)
  • Pregnancy and breastfeeding
