Choosing Between PT-141 and Oxytocin for Sexual Wellness
Invigor Medical offers both PT-141 and Oxytocin, each with distinct benefits. PT-141 works by activating melanocortin receptors, which can enhance sexual arousal, while Oxytocin supports emotional bonding and intimacy. Depending on individual needs, patients may benefit from the direct arousal effects of PT-141, the mood-enhancing properties of Oxytocin, or a combination of both for a more comprehensive approach to sexual wellness.
