KPV (Lysine-Proline-Valine) is a C-terminal tripeptide fragment of alpha-melanocyte-stimulating hormone (alpha-MSH) that inhibits NF-kB signaling through a non-melanocortin receptor-mediated mechanism. It is transported intracellularly via the PepT1 transporter, where it stabilizes IkB-alpha and suppresses nuclear translocation of p65RelA by competing with importin-beta at the armadillo domain 7 and 8 binding site. It also reduces MAPK inflammatory signaling and IL-8 secretion in intestinal epithelial cells.
Research indicates 200-500 mcg daily via subcutaneous injection, or 500 mcg-1 mg orally for gut-targeted inflammation.

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.
Morning administration preferred. Can be dosed pre-workout for enhanced exercise performance.
8-16 week cycles.
