Bremelanotide Acetate PT-141 with Cyanocobalamin Injectable (20mg/1000mcg) is a clinically compounded peptide formulation combining PT-141 — a melanocortin receptor agonist — with B12 (cyanocobalamin) for enhanced absorption and energy support.

Unlike traditional sexual health medications that work through vascular mechanisms, PT-141 acts directly on the central nervous system to stimulate desire and arousal in both men and women. It's one of the few peptides with clinical evidence supporting improved libido, sexual function, and arousal response — making it a popular addition to hormone optimization protocols where low libido persists even after testosterone levels are corrected.

The addition of cyanocobalamin (Vitamin B12) supports neurological function, energy metabolism, and may enhance the overall tolerability of the injection.

Commonly prescribed for men and women experiencing low sexual desire, difficulty with arousal, or libido concerns that haven't fully resolved with hormone therapy alone. Administered subcutaneously as needed, typically 45–60 minutes before sexual activity.

Prescribed as part of a personalized WRC peptide therapy plan. Requires provider consultation and lab review prior to dispensing.
