PT-141 (Bremelanotide) 10MG

PT-141, also called Bremelanotide (generic clinical name), is a heavily modified synthetic derivative of alpha-melanocyte-stimulating hormone. It has been tested in clinical trials as a treatment for both male/female hypoactive sexual desire disorder and acute hemorrhage. PT-141 is an agonist for the melanocortin-4 and melanocortin-1 receptors. Research shows that it promotes sexual arousal and stimulates the immune system.

PT-141 is a synthetic variant of the naturally occurring peptide hormone alpha-melanocyte stimulating hormone (α-MSH)1 and has been proven as an effective agent for the improvement of sexual dysfunction in both male and female animal test subjects2.

Naturally occurring α-MSH acts as an agonist of melanocortin receptors MC1, MC3, and MC4; receptor MC1 has been shown to be responsible for skin pigmentation effects, while MC3 and MC4 are responsible for effects on appetite, metabolism, and sexual activity3. Using this understanding of the native peptide, PT-141 was developed as an agent meant only to bind melanocortin receptors MC3 and MC4, thereby acting as a selective stimulator of cellular metabolic and erectile effects4.

PT-141 has been shown to be a lipolytic (fat cell-destroying) agent5, a suppressant of appetite6, and a stimulant of libido in animal test subjects4. PT-141 has demonstrated great efficacy in reducing caloric intake, while eliminating cholesterol and fat stores in obese mice through its targeted metabolic action7.

Product Comparison

PT-141 is structurally similar to the biosynthetic peptide hormone Melanotan II, but has shown to be a potent binding agent of MC3 and MC4 only, demonstrating no affinity for MC1. In animal tests, PT-141 has proven quite effective at correcting sexual dysfunction2, while Melanotan II induces an additional effect on skin tone.

Unlike other agents that have an effect on erectile response (e.g. Viagra), PT-141 performs no action on the vascular system, but rather induces arousal and heightens sexual desire via the nervous system – binding important receptors in the brain8.

Melatonan I is also structurally similar to PT-141, both being synthetic analogues of α-MSH, but Melanotan I is only active in binding the MC1 receptor3, thereby producing skin tanning effects and neglecting any stimulation of sexual response. Though these agents look alike, they could not be more separate in function.
