MOTS-c is a 16-amino acid mitochondrial-derived peptide encoded by the 12S rRNA gene of the mitochondrial genome. It primarily acts through the folate-AICAR-AMPK pathway: by regulating the folate cycle and de novo purine biosynthesis, it increases AICAR accumulation, which phosphorylates and activates AMPK. This enhances glucose uptake in skeletal muscle, improves insulin sensitivity, and mimics exercise-mediated physiological responses. Skeletal muscle MOTS-c levels increase 11.9-fold in response to acute exercise in young men.
Research indicates 5-10 mg administered 3-5 times per week via subcutaneous injection.

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.
Administer on an empty stomach. Inject near site of injury for localized effect.
4-12 weeks depending on therapeutic target.
