Standard DoseResearch indicates 250-500 mcg administered 1-2 times daily via subcutaneous injection near the site of injury.Research indicates 100-300 mcg administered 1-3 times daily via subcutaneous injection.
TimingAdminister on an empty stomach or near the injury site. No strict meal timing required, though fasted state may improve absorption for oral dosing.On empty stomach, 30+ minutes before meals. Bedtime dose most important. The strong hunger effect makes pre-meal timing practical.

BPC-157

Peptides

Mechanism

BPC-157 is a 15-amino acid peptide derived from human gastric juice that promotes angiogenesis via dual VEGFR2-dependent (PI3K-Akt-eNOS) and VEGF-independent (Src-Caveolin-1-eNOS) nitric oxide pathways. It upregulates growth hormone receptor expression, modulates the FAK-paxillin pathway for cell migration, and counteracts damage to the nitric oxide system. Additionally, it enhances tendon fibroblast growth, promotes reticulin and collagen formation, and accelerates wound healing by mediating the NO system's protective functions.

Standard Dosing

Research indicates 250-500 mcg administered 1-2 times daily via subcutaneous injection near the site of injury.

Timing

Administer on an empty stomach or near the injury site. No strict meal timing required, though fasted state may improve absorption for oral dosing.

Cycle Duration

Typical cycles range from 4-12 weeks depending on the injury being addressed.

Side Effects

  • Mild nausea (rare)
  • Dizziness (rare)
  • Injection site irritation
  • Headache (uncommon)

Contraindications

  • Active cancer or history of cancer (theoretical concern with angiogenesis promotion)
  • Pregnancy and breastfeeding
  • Children under 18

GHRP-6

Peptides

Mechanism

GHRP-6 (Growth Hormone Releasing Peptide-6) is a synthetic hexapeptide that stimulates GH release through activation of the growth hormone secretagogue receptor (GHS-R1a/ghrelin receptor) on pituitary somatotrophs. It acts via dual sites — pituitary and hypothalamic — possibly involving regulatory factors beyond GHRH and somatostatin. GHRP-6 also stimulates ghrelin-mediated appetite signaling, increases cortisol and prolactin release, and has demonstrated cytoprotective properties including cardioprotection.

Standard Dosing

Research indicates 100-300 mcg administered 1-3 times daily via subcutaneous injection.

Timing

On empty stomach, 30+ minutes before meals. Bedtime dose most important. The strong hunger effect makes pre-meal timing practical.

Cycle Duration

8-16 week cycles.

Side Effects

  • Intense hunger (primary distinguishing side effect)
  • Water retention
  • Cortisol elevation
  • Prolactin elevation
  • Tingling and numbness
  • Injection site pain

Contraindications

  • Active cancer
  • Obesity (significant appetite stimulation)
  • Cushing's syndrome
  • Pregnancy and breastfeeding
