What is PT-141 and what is SNAP-8?
PT-141 is classified as Synthetic cyclic heptapeptide melanocortin agonist; SNAP-8 as Synthetic acetylated octapeptide. Both profiles below cover scientific identity only — what the molecule is and which laboratory models it appears in. Verve supplies both strictly as in-vitro reference materials, and neither profile describes human or veterinary use.
PT-141
Synthetic cyclic heptapeptide melanocortin agonist
PT-141, also known as bremelanotide, is a synthetic cyclic heptapeptide analog of the melanocortin family, structurally related to alpha-melanocyte-stimulating hormone and to the earlier research analog Melanotan II. Verve supplies it as a high-purity research compound for laboratory melanocortin-receptor research.
full PT-141 profile →SNAP-8
Synthetic acetylated octapeptide
SNAP-8 is a synthetic acetylated octapeptide, an elongated analog of acetyl hexapeptide-3 (Argireline) extended by two additional residues. Its sequence is modeled on the N-terminal region of SNAP-25, one of the proteins that assembles the SNARE complex, which makes it a convenient synthetic tool for studying that assembly in vitro.
