Reconnect with desire on your terms.
Compounded PT-141 supports sexual desire and arousal at the brain level — an on-demand peptide for intimacy.
PT-141 (bremelanotide) is a melanocortin-receptor agonist, a peptide that activates the same hypothalamic pathways your brain already uses to coordinate sexual desire and arousal. It works upstream of blood flow, distinct from PDE5 inhibitors like Viagra and Cialis.
By engaging the central desire circuit rather than the vascular system, PT-141 may support intimacy for adults whose challenges are not solved by blood-flow drugs — including women with HSDD and men who do not respond to PDE5 inhibitors. A balanced, science-based approach to strength.

What patients say
Real outcomes from people on this protocol, all under doctor supervision.
“Honestly skeptical going in. Took 1 mg the first time, mostly to see how I would feel. Mild flushing, a little nausea, but the desire piece was real. Moved to the standard dose two weeks later.”
Jenna P.
Asheville, NC
“PDE5 drugs never really worked for me — the issue was never blood flow, it was interest. PT-141 hits the upstream switch. Different category of medication entirely.”
Michael K.
Eugene, OR
“My doctor walked me through cardiovascular screening before prescribing, including a home BP cuff check. The medical intake felt thorough, not rushed. That mattered to me.”
Rachel S.
Burlington, VT
“Nausea was rough on the first 1.75 mg dose. Care team suggested ginger 30 min before injection and a smaller meal. Second dose was much better and now I plan around it.”
Sara D.
Providence, RI
“After menopause my OB had limited options that were not hormonal. PT-141 has been a quiet game-changer for our marriage. The on-demand part is what makes it usable.”
Diane B.
Santa Fe, NM
“I appreciated that the doctor told me to stop if it was not working at 8 weeks instead of pushing more vials. It worked for me, but the honesty up front built trust.”
