PT-141

Peptide

Supports sexual desire and responsiveness by acting directly on the brain.

PT-141 is a peptide that targets the brain's sexual arousal pathways to enhance desire and responsiveness. Unlike traditional blood-flow medications, it works by activating melanocortin receptors upstream of the vascular system. It is designed as an as-needed, on-demand option for both men and women experiencing low libido.

Suggested use: Typically taken as a subcutaneous injection about 45 minutes before anticipated activity. Limit use to no more than one dose per 24 hours, and generally no more than two to three times per week or eight times per month.

PT-141

Sexual Desire & Arousal Support

WHAT IT IS:

A peptide that works in the brain's of both men’s and women’s sexual arousal pathways rather than on blood flow — activating melanocortin receptors to enhance sexual desire and responsiveness.

WHY YOU NEED IT:

Acts on Desire, Not Just Blood Flow

Important for patients with low libido or hypoactive sexual desire

Supports patients for whom blood-flow medications (like PDE5 inhibitors —Viagra, Cialis) haven't fully helped

Good for patients seeking an on-demand, as-needed option

Great for both women and men exploring desire-focused support

Supports patients pursuing a comprehensive, physician-guided sexual-health plan

Important for patients who want a mechanism distinct from vascular-only therapies

HOW IT HELPS:

Sexual health involves more than circulation — desire itself originates in the brain. PT-141 is designed to engage those central arousal pathways directly.

A Brain-Based Mechanism

PT-141 (bremelanotide) stimulates the brain’smelanocortin receptors. By activating melanocortin pathways involved in arousal, it works upstream of the vascular system — addressing desire rather than simply enabling blood flow. This sets it apart from medications such as Viagra or Cialis, which only target circulation.

An FDA-Approved Foundation

Bremelanotide is FDA-approved for hypoactive sexual desire disorder in premenopausal women, supported by two Phase 3 trials. Research has also explored its use in men with sexual dysfunction.

What to Expect

PT-141 is taken as needed, typically by subcutaneous injection about 45 minutes before anticipated activity, with effects reported to last for a number of hours. The most common side effects are nausea, flushing, and headache; transient increases in blood pressure can occur, so it is not appropriate for patients with uncontrolled hypertension or significant cardiovascular disease.

Who Should Not Use PT-141

PT-141 is not appropriate for patients with uncontrolled high blood pressure or known cardiovascular disease, women who are pregnant or breastfeeding, or patients with a known hypersensitivity. Dosing frequency should not exceed label guidance. Use only under physician supervision.

DOSAGE:

Limits: No more than one dose per 24 hours and generally no more than two to three times in a week or eight per month; use should be individualized and supervised by a physician.
