— Product Overview
Description
PubChem lists KPV as both alpha-MSH (11-13) and ACTH-(11-13), because alpha-MSH has the same 13-residue sequence as the start of ACTH. Residues 4-7 of that sequence, Met-Glu-His-Phe, are also the first four residues of Semax.
This KPV is the free acid. In alpha-MSH the valine at position 13 is amidated, so an amidated Lys-Pro-Val-NH2 would be about 1 Da lighter (monoisotopic 341.24 Da, against 342.23 Da here). With a free N-terminus and a lysine side-chain amine against one carboxyl group, KPV carries a net positive charge near neutral pH.
KPV comes as a 10mg vial, and it is also pre-mixed with GHK-Cu, BPC-157 and TB-500 in the KLOW blend. For research use only. Not for use in humans or animals.
