PT-141, also known as bremelanotide, is one of the best-known peptides in the libido and arousal category. It is commonly discussed for sexual desire, arousal signaling, and central melanocortin receptor research.
Most people looking at PT-141 are interested in libido, desire, and arousal support research rather than a simple blood-flow mechanism. That distinction matters: PT-141 is usually discussed as a brain and melanocortin-pathway peptide, not as a conventional vascular ED-style product.
Mechanistically, PT-141 acts through melanocortin receptors, especially pathways involving MC3 and MC4 signaling. That central mechanism is why PT-141 is commonly compared against other libido-support options.
Each vial contains 10mg of lyophilized PT-141 powder for reconstitution with bacteriostatic water.
Reconstitution: Reconstitute with bacteriostatic water. Add the water slowly down the inside wall of the vial and let the powder dissolve gently. Do not shake.
Storage: Store at -20 degrees C in lyophilized form. Refrigerate reconstituted solution at 2-8 degrees C and use within 30 days. Protect from light.
For Research Purposes Only. Not for human consumption. Not for veterinary use. Sold strictly for in vitro and laboratory research applications.
