Evidence brief

Bremelanotide

Written and source-checked by Anthony Treviso, founder of The Peptide Field.

Direct answer

An FDA-approved product exists for a narrow indication.

An approved medicine for one defined sexual-desire disorder. It is not a general sexual-performance enhancer.

How strong is the evidence?
Established
An official agency review or strong, repeated studies in people support one clear use. That evidence applies only to the product, people, and use we reviewed. It does not mean the product is safe or effective for everyone.
What evidence exists?
Approved human outcomes
Approved products have evidence from studies in people that measured health results for specific uses. This does not show that every product, person, or use has the same result.
Sports rules
Not assessed
No current sports-rule review is available.

01 · Evidence profile

Four questions about the evidence

Benefits in peopleDid people have a meaningful health benefit?
ModerateUseful human evidence exists, but important limits remain.

Two phase 3 trials support modest changes in prespecified desire and distress endpoints for the labeled population.

Body changes in peopleDid a study measure how it changed the body in people? This alone does not show a health benefit.
StrongSeveral reliable sources describe this clearly.

Exposure and transient cardiovascular effects are characterized in the approved label.

Known risksHow much do studies tell us about risks in people?
StrongSeveral reliable sources describe this clearly.

The label describes blood-pressure effects, contraindications, nausea, pigmentation, and other risks.

Exact productHow certain are the product identity and quality?
StrongSeveral reliable sources describe this clearly.

High for authentic Vyleesi; evidence does not automatically transfer to compounded PT-141.

02 · Identity

What it is

Bremelanotide is the active ingredient in Vyleesi and acts on melanocortin receptors. The approved use has diagnosis, population, and exclusion criteria.

Scientific group: Melanocortin receptor agonist. This group name describes the type of molecule or body signal. It does not prove a benefit, safety, or approval.

03 · Exact product

The molecule is not the finished product.

Formulation: The finished product's ingredients and physical form. Route: How the product enters the body. Indication: The approved or studied use and group of people for a product.

04 · Research results

What the research shows

What the evidence shows

The RECONNECT phase 3 trials reported improvements in planned measures of desire and distress in premenopausal women with acquired, generalized HSDD. HSDD is a diagnosed form of low sexual desire. The label says it is not indicated to enhance sexual performance.

What remains unknown

The evidence does not establish treatment of all causes of low desire, benefit in men or postmenopausal women, a relationship benefit for everyone, or equivalence of compounded PT-141.

Exact product

Evidence for Vyleesi does not automatically apply to every PT-141 product. Vyleesi is an approved, product-specific presentation. Calling any PT-141 product 'Vyleesi' or transferring its evidence to compounded material is not justified.

Claims I checked

3 claims checked for this brief.

Approval and statusWhether a specific product has an approval or another official status.

“Bremelanotide is FDA-approved for a specific form of HSDD.”

Supported with scopeThe reviewed evidence supports this exact statement only in the situation described below.

Vyleesi is approved for acquired, generalized HSDD in certain premenopausal women after specified exclusions.

Evidence used
Regulatory or product record. This answer uses an official regulator record or a specific product label.
Limits of this answer
The population and limitations in the current Vyleesi label. This answer covers only the named molecule and finished product. It also covers the product form and how people used it. The study limits include who took part, what was used for comparison, what changed, and how long the study lasted.

Clinical outcomesWhat a study measured about people's health, symptoms, or ability to function.

“PT-141 is an approved sexual-performance enhancer for anyone.”

MisleadingThis statement leaves out a limit that changes its meaning.

The label explicitly says the product is not for enhancing sexual performance and is not indicated for men or postmenopausal women.

Evidence used
Regulatory or product record. This answer uses an official regulator record or a specific product label.
Limits of this answer
Vyleesi's labeled indication and limitations. This answer covers only the named molecule and finished product. It also covers the product form and how people used it. The study limits include who took part, what was used for comparison, what changed, and how long the study lasted.

Product equivalenceWhether evidence for one product also applies to another product.

“Compounded PT-141 has the same evidence as Vyleesi.”

Not establishedThe reviewed evidence does not establish this statement. This does not prove it can never be true.

The trial and approval record are product-specific and do not establish equivalence for compounded material.
