|---|---|---|
| Category | Peptides | Growth Factors |
| Standard Dose | Research indicates 250-500 mcg administered 1-2 times daily via subcutaneous injection near the site of injury. | Research indicates 200-500 mcg administered 2-3 times per week via subcutaneous or intramuscular 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 non-training days or several hours post-workout (to avoid competing with natural MGF pulse). Unlike native MGF, timing is more flexible due to extended half-life. |
| Cycle Duration | Typical cycles range from 4-12 weeks depending on the injury being addressed. | 4-8 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.

PEG-MGF is the pegylated form of Mechano Growth Factor, where polyethylene glycol (PEG) molecules are covalently attached to protect against rapid enzymatic breakdown. This extends the half-life from 5-7 minutes (native MGF) to approximately 48-72 hours. Like native MGF, it activates satellite cell proliferation, promotes muscle fiber regeneration and hypertrophy, and supports tissue repair. The extended half-life allows for systemic distribution rather than purely local action, enabling subcutaneous rather than intramuscular administration.
Research indicates 200-500 mcg administered 2-3 times per week via subcutaneous or intramuscular injection.
