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.

Pentadeca Arginate is a synthetic 15-amino acid peptide utilizing an arginate salt formulation of the BPC-157 sequence, designed to enhance nitric oxide production and promote angiogenesis. It stimulates collagen synthesis, enhances tissue repair through increased tensile strength, reduces inflammation via modulation of inflammatory cytokines, and accelerates cellular proliferation in tendon fibroblasts. The arginate salt form provides superior stability and bioavailability compared to traditional acetate formulations.
Research indicates 250-500 mcg administered 1-2 times daily via subcutaneous injection.
