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.
