what each one is
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.

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.
