A melanocortin-based peptide studied for its ability to enhance libido, arousal, and sexual function – with effects independent of hormonal or vascular pathways.
For Research Use Only
This product is intended for laboratory research use only (in vitro studies). Not for human or animal consumption, and not for any therapeutic or diagnostic use.
PT-141, also known as Bremelanotide in its generic clinical name, represents a heavily modified synthetic derivative of alpha-melanocyte-stimulating hormone. In clinical trials, it has been examined as a potential treatment for a lack of sexual desire in both males and females. This synthetic peptide acts as an agonist for the melanocortin-4 (MC-4R) and melanocortin-1 (MC-1R) receptors.
The primary focus of PT-141 revolves around its ability to promote sexual arousal. The peptide’s mechanism involves binding primarily to the MC-4R and MC-1R, which are implicated in the regulation of sexual function.
Research suggests that PT-141’s agonistic action on melanocortin receptors extends beyond sexual arousal, with implications for its involvement in immune system stimulation. This multifaceted nature positions PT-141 as a peptide with diverse therapeutic potential.
Derived from melanotan 2 (MT-2), PT-141 inherits its lineage from synthetic melanocortins. The exploration of PT-141’s various applications underscores its significance in addressing both physiological and clinical challenges.
