Freezable? ✅ Yes
PT-141 (Bremelanotide) is a synthetic peptide that is used for the treatment of sexual dysfunction in both men and women.
Mechanism
Unlike PD5 inhibitors (like Viagra) which act on the vascular system, PT-141 is a melanocortin agonist that acts directly on the central nervous system to increase sexual desire and arousal.
Usage Note
PT-141 has a relatively long induction period, with effects often peaking 2-6 hours after administration. Its potency is highly dependent on proper refrigerated storage to prevent peptide denaturation.
