PT-141
PT-141 Product Description — Research Use Only
PT-141, also known as Bremelanotide, is a synthetic research peptide analog of alpha-melanocyte-stimulating hormone, commonly known as alpha-MSH. It is commonly studied for melanocortin receptor activity, neuroendocrine signaling, central nervous system response, sexual-response pathways, and behavioral-signaling research. Published literature describes PT-141 as a melanocortin receptor agonist with activity at MC3R and MC4R pathways.
Research on PT-141 has most commonly focused on melanocortin receptor activity, arousal-response pathways, sexual-behavior research, central nervous system signaling, neuroendocrine response, mood-related pathways, and vascular-response markers. Unlike PDE5-focused compounds, PT-141 research is primarily centered on central melanocortin signaling rather than direct vascular smooth-muscle relaxation pathways.
PT-141 is commonly studied for:
Melanocortin receptor activity — how PT-141 interacts with MC receptor pathways
Arousal-response research — pathways connected to central nervous system arousal signaling
Sexual-behavior pathways — how melanocortin signaling influences behavioral-response models
Neuroendocrine signaling — how brain and hormone-related signals communicate
Central nervous system response — how receptor activity in the brain affects downstream signaling
Vascular-response research — how arousal-related pathways may connect with blood-flow markers
Mood and motivation pathways — how melanocortin signaling may influence behavioral drive
PT-141 is commonly studied because melanocortin receptors are involved in multiple signaling systems. MC3R and MC4R pathways are especially relevant in central nervous system research involving arousal, motivation, appetite, and neuroendocrine activity. Clinical research has evaluated PT-141/Bremelanotide in sexual-response models, including studies measuring subjective arousal, desire, and related behavioral-response markers.
