Is PT-141 Banned in Sports? Bremelanotide, WADA and Drug Tests

PT-141 is bremelanotide, a melanocortin receptor agonist and a metabolite of Melanotan II, developed for sexual desire. It acts on the brain's melanocortin system rather than on blood flow. Two phase 3 randomised trials in 1,267 premenopausal women with acquired, generalised hypoactive sexual desire disorder, published in Obstetrics & Gynecology in 2019, supported an FDA-approved drug with the same active ingredient, approved on 21 June 2019. More is in what is PT-141.

The Prohibited List is published every year and comes into force on 1 January. The 2026 List does not name bremelanotide, oxytocin or Melanotan II. It does name kisspeptin and its agonist analogues under S2.2.1, testosterone-stimulating peptides prohibited in males, and MOTS-c under S4.4.1 as an AMPK activator.

That contrast matters for anyone choosing between libido options, because the products in this category do not share one anti-doping position.

Prices are all-in monthly figures covering medication, physician review, refill management and shipping, with no membership fee. Compounded medications are not FDA approved. The direct comparison is in kisspeptin vs PT-141.

Why "not named" is not the same as "cleared"

The List has a catch-all class, S0, covering any pharmacological substance not addressed by another section "and with no current approval by any governmental regulatory health authority for human therapeutic use." WADA's own explanatory note warns that a substance not specifically named "may still be prohibited." S0 is written around the absence of approval; bremelanotide is the active ingredient of an FDA-approved product. How that applies to a compounded vial in your sport is for your anti-doping body to answer, not a web page.

Sports outside the Code also matter. Professional leagues, military services and some employers run their own policies, and they need not match the WADA List.

Anti-doping rules operate independently of prescribing law. Article 2.1.1 of the World Anti-Doping Code makes it each athlete's personal duty to ensure that no prohibited substance enters their body, and says intent, fault, negligence or knowing use need not be shown to establish a violation. That is strict liability.

For PT-141 the practical point is not the molecule, which is unnamed, but certainty about what is in the vial. A product bought "for research use only" carries no accountability for identity or purity, and a vial contaminated with or substituted by a named substance is the athlete's problem under strict liability. A prescription filled by a licensed pharmacy with published lot testing is the version where you know what you took.

If your anti-doping body tells you a product is prohibited for you, a therapeutic use exemption granted in advance is the only route to permitted use. In the United States, USADA directs athletes outside its testing pools to its TUE Pre-Check Form, with a stated response time of three to five business days.

College athletes are governed by the NCAA's banned drug classes rather than the WADA List. One class is "peptide hormones, growth factors, related substances and mimetics," and the NCAA states that any substance chemically or pharmacologically related to a banned class is also banned even if not named, with the school and the student-athlete both accountable. Bremelanotide is not among the NCAA's published examples. Route the question through your athletics health care provider before starting.

The wider comparison of the two testing systems is in do peptides show up on a drug test.

Because bremelanotide is a component of an FDA-approved product, it may be used in 503A compounding without depending on the bulks list, and it was never in Category 2. A compounded PT-141 vial is a different formulation, prepared by a licensed pharmacy to an individual prescription; it has not been reviewed by the FDA and is not FDA approved. Prescribing it after menopause, or to men, is off-label use of an approved active. More is in PT-141 benefits and PT-141 side effects.

Who should not take PT-141, or should discuss it first, is a medical question rather than a sport one: anyone with uncontrolled high blood pressure or heart disease, anyone taking oral naltrexone, anyone with a history of melanoma or atypical moles, and anyone pregnant or breastfeeding, where it is not used.

PT-141 cannot be bought legitimately without a prescription. Sites selling it "for research use only" are not accountable for what is in the vial: identity, purity, sterility and concentration are untested. The prescription route:

1. Complete a free online intake covering your history, medications and what you want help with. If you are subject to anti-doping testing, say so there.
2. A physician licensed in your state reviews it, usually within 24 hours.
3. If it is appropriate, a state-licensed, FDA-registered US pharmacy compounds it to that prescription. Lot test results are published at /quality/lab-results.
4. It ships refrigerated with your directions printed on the vial, with sterile syringes and alcohol prep pads.
5. Your physician stays reachable for questions through your account.
