| Category | Peptides | Peptides |
| Standard Dose | Research indicates 250-500 mcg administered 1-2 times daily via subcutaneous injection near the site of injury. | Research indicates 10-20 mg daily via oral or sublingual administration. |
| 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. | Morning dosing preferred. Can be taken with or without food (orally active). |
| Cycle Duration | Typical cycles range from 4-12 weeks depending on the injury being addressed. | 2-4 week cycles with equal rest periods. Long-term safety data is extremely limited. |

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.

Dihexa (N-hexanoic-Tyr-Ile-(6)-aminohexanoic amide) is an orally active, blood-brain barrier-permeable oligopeptide derived from angiotensin IV. It binds hepatocyte growth factor (HGF) with high affinity, inhibiting HGF dimerization and synergistically promoting c-Met receptor phosphorylation and signaling. Activation of HGF/c-Met drives procognitive effects through increased dendritic arborization, spinogenesis, and synaptogenesis via the PI3K/AKT signaling pathway. Research indicates it is approximately 10 million times more potent than BDNF for new synapse formation.
Research indicates 10-20 mg daily via oral or sublingual administration.
Morning dosing preferred. Can be taken with or without food (orally active).
2-4 week cycles with equal rest periods. Long-term safety data is extremely limited.
