What's in the cartridge
Combines Semax, an ACTH(4-10) analogue studied for BDNF/NGF expression and neuroprotection, with PT-141 (bremelanotide), a cyclic heptapeptide melanocortin receptor agonist acting centrally via MC3R/MC4R in hypothalamic and limbic pathways, and KPV, the C-terminal tripeptide fragment of alpha-MSH studied for receptor-independent NF-κB inhibition and cytokine suppression. Three compounds spanning distinct but overlapping alpha-MSH-related and neurological research areas, supplied as three separate ready-to-use liquid peptide pens, sold together at a stack discount.
