PT-141 is a synthetic analogue of 𝛂-melanotropin. Like Melanotan – it was created to treat sexual dysfunction and erection problems. Unlike Melanotan, however, it does not affect skin pigmentation. This is because PT-141 is an agonist only at melanocortin 3 and 4 receptors, the stimulation of which is responsible for the activation of the oxytocin and dopamine systems – involved in the regulation of sexual drive. Such precisely targeted stimulation helps to achieve a huge improvement in sexual function, including an erection that lasts up to two hours.
