Approval and product status

An FDA-approved product exists for a narrow indication

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.

What was measured in people?

Health results · Moderate
Two phase 3 trials support modest changes in prespecified desire and distress endpoints for the labeled population.
Body changes · Strong
Exposure and transient cardiovascular effects are characterized in the approved label.

A change in a hormone or body signal does not by itself prove a health benefit.

Important limits

This tool is not an independent medical review. It does not recommend treatment.

The label says the product must not be used with uncontrolled hypertension or known cardiovascular disease. It also describes temporary blood-pressure increases. This guide provides no dosing or injection advice.

Still 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.

This record cannot check a package, seller, batch, or personal treatment. It does not provide sport clearance.

What this checker shows

Why approval and research can differ

Approval applies to an exact product and use. Research may cover a different form, group of people, or outcome.

This tool keeps those questions separate. There is no safety score or treatment ranking.

Check the sources.

Results use this site’s reviews. They show source dates, product labels, study limits, and links to the original records.

The checker gives no answer for an unknown name. A listed entry without a full review stays marked as incomplete.
