PT-141, also known as Bremelanotide, is a synthetic melanocortin receptor agonist derived from the α-melanocyte-stimulating hormone (α-MSH) peptide structure. Unlike phosphodiesterase inhibitors, PT-141 acts directly on the central nervous system, particularly through MC3R and MC4R receptors in the hypothalamus, to enhance sexual desire and arousal. Research has shown that PT-141 may increase sexual motivation and responsiveness without affecting vascular…
RAD-140, also known as Testolone, is a non-steroidal selective androgen receptor modulator (SARM) designed to mimic the anabolic effects of testosterone with greater tissue selectivity. It binds specifically to androgen receptors in muscle and bone, activating anabolic pathways without significantly affecting other androgen-responsive tissues, such as the prostate. Research on RAD-140 has focused on its potential to increase lean muscle…
