| Standard Dose | Research 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. |
| 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. | On empty stomach, 30+ minutes before meals. Bedtime dose most important. The strong hunger effect makes pre-meal timing practical. |
| Cycle Duration | Typical cycles range from 4-12 weeks depending on the injury being addressed. | 8-16 week cycles. |

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

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.
Research indicates 100-300 mcg administered 1-3 times daily via subcutaneous injection.
On empty stomach, 30+ minutes before meals. Bedtime dose most important. The strong hunger effect makes pre-meal timing practical.
