Peptides for Sexual Health Research PT-141 · Melanotan II · Tadalafil · Melanocortin Receptor Research · ≥99% HPLC · Janoshik COA
Sexual health peptide research targets melanocortin receptor pathways (PT-141/Bremelanotide via MC4R/MC3R), broader melanocortin signaling (Melanotan II via MC1R/MC4R), and PDE5 vasodilation research (Tadalafil). These compounds represent distinct mechanisms in central and peripheral sexual function research. QSC stocks all at ≥99% HPLC with Janoshik COA.
PT-141 (Bremelanotide) is a synthetic melanocortin receptor agonist that acts primarily on MC4R and MC3R in the central nervous system. Unlike PDE5 inhibitors, PT-141 operates through a central mechanism rather than direct vascular action. It has been studied in both male and female sexual dysfunction research models. QSC stocks PT-141 at ≥99% HPLC with Janoshik COA. Research use only.
What is the difference between PT-141 and Melanotan II?
PT-141 (Bremelanotide) is a selective MC3R/MC4R agonist derived from Melanotan II but without the alpha-MSH/MC1R tanning activity. Melanotan II is a broader non-selective melanocortin agonist that activates MC1R (skin tanning), MC3R, and MC4R simultaneously. Research applications differ accordingly. QSC stocks both. Research use only.
