What is PT-141 (Bremelanotide)?

PT-141 is a bioactive melanocortin analog derived from Melanotan II, engineered to focus on central melanocortin pathways rather than peripheral vasodilation.
In laboratory settings, it modulates hypothalamic neurotransmission, offering researchers a reliable tool for studying dopaminergic activity, sexual motivation, and energy regulation.

Key Features

• 💎 ≥ 98 % Purity (HPLC & MS Verified)

• 🧬 Selective MC3R / MC4R agonist

• ⚗️ Ideal for neuroendocrine and sexual behavior research

• 🔬 Cyclic peptide with enhanced receptor stability

• 🧊 Lyophilized form for long shelf life and purity preservation

Mechanism of Action

PT-141 binds to melanocortin-3 and melanocortin-4 receptors in the central nervous system.
Activation of these receptors triggers cAMP signaling, influencing dopamine and hypothalamic pathways related to arousal, motivation, and energy homeostasis.
