Cerebrolysin is a porcine brain-derived peptide preparation containing a standardized mixture of low-molecular-weight neuropeptides (<10 kDa) and free amino acids obtained through enzymatic proteolysis. It exerts multimodal neurotrophic effects by simultaneously upregulating VEGF, BDNF, IGF-1, and NGF while downregulating TNF-alpha. Cerebrolysin increases furin protease concentration, which promotes pro-NGF to mature NGF conversion. It activates TrkB receptor signaling (BDNF/TrkB/CREB pathway), inhibits neuronal apoptosis, reduces microglial activation, and promotes neurogenesis.

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.
