PT-141
A peptide in the bremelanotide class studied for its role in the desire and arousal pathways of sexual response.
A peptide studied for desire and arousal
PT-141 (bremelanotide) is a peptide that acts on receptors in the brain rather than on blood flow. In research settings it has been studied for its role in the desire and arousal pathways that shape sexual response. At Meridian it is offered as a compounded medication — meaning it is prepared by a licensed pharmacy — and is used as needed, only under a provider’s guidance.
Working through the brain’s arousal pathways
Research suggests PT-141 may act on melanocortin receptors in the central nervous system — pathways involved in sexual desire — rather than on the vascular system that many other options target. It is typically administered as a small subcutaneous dose taken as needed, ahead of intimacy.
- ✓May act on melanocortin receptors involved in sexual desire
- ✓Studied for arousal that begins in the brain, not blood flow
- ✓Delivered as a provider-guided dose taken as needed

This is general education, not medical advice. Whether PT-141 is appropriate for you is determined by a licensed provider.
Why oversight matters here
This is a compounded medication, so a licensed provider must confirm it’s appropriate for you before it can be dispensed. The review checks your health history, current medications, and goals to ensure it’s a safe fit.
This therapy requires review by a licensed provider before it can be dispensed. You’ll complete a short online visit; a provider evaluates whether it’s appropriate for you and, if so, authorizes it.

From first visit to follow-up — calm, transparent, and guided by a licensed provider throughout.
What the research explores
A plain-language look at the areas of study. Research is evolving and varies in strength — we present it honestly, not promotionally.
Clinical studies have examined bremelanotide’s effects on sexual desire, primarily in premenopausal women. Research in other groups remains limited.
Much of the research explores how the peptide activates melanocortin receptors in the brain rather than acting on blood flow.
Studies have investigated its use as an on-demand dose taken ahead of intimacy, rather than a daily regimen.
Compounded PT-141 is not FDA-approved. While bremelanotide has been studied clinically, the compounded form is prepared by a licensed pharmacy and used under a provider’s guidance.
Our Science Library — evidence summaries, mechanisms, limitations, and provider commentary — is expanding.
PT-141, answered
No. The compounded form we offer is prepared by a licensed pharmacy, not an FDA-approved drug. It is provided only when a licensed provider determines it is appropriate for you.
Typically as a small subcutaneous injection taken as needed, ahead of intimacy. Your provider will give you specific dosing guidance and everything needed to administer it.
Yes. This therapy requires provider review. You’ll complete a short free online visit, and a provider decides whether to authorize it.
For ongoing intimacy and sexual-health goals, membership adds check-ins, tracking, and provider adjustments over time — but it isn’t required for a reviewed purchase.
