PT-141

PT-141 (Bremelanotide) is a synthetic melanocortin receptor agonist studied as a ligand probe for melanocortin receptor pharmacology. Experimental systems evaluate its interaction with MC3R and MC4R receptors and associated second-messenger signaling pathways. Laboratory investigations focus on receptor activation dynamics and neuroendocrine signaling mechanisms under controlled research conditions without implying human outcomes.

Products will arrive in a lyophilized (powder) form to maximize stability and shelf life.

What It Is	PT-141 (Bremelanotide) is a synthetic melanocortin receptor agonist structurally derived from melanotan-class peptides and studied in laboratory models of melanocortin receptor signaling.
What It’s Derived From	PT-141 is derived from modified analogues of α-melanocyte–stimulating hormone (α-MSH), including melanotan II–related sequences, and is engineered to act on melanocortin receptor subtypes with defined receptor selectivity.
What Research Focuses On	Research evaluates PT-141 in in vitro and preclinical models examining melanocortin receptor (MC3R and MC4R) activation, ligand–receptor selectivity, GPCR-mediated second-messenger signaling cascades, and neuroendocrine pathway mapping under controlled experimental conditions.
