what each one is
GLOW
Co-formulated three-peptide research blend
GLOW is a co-formulated research blend that combines three well-characterized reference peptides — GHK-Cu, BPC-157, and TB-500 — in a single vial. Each component is independently established in the literature: GHK-Cu as a copper-binding tripeptide, BPC-157 as a synthetic pentadecapeptide, and TB-500 as a fragment of the actin-binding protein thymosin beta-4.

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.
