Is PT-141 the same as Vyleesi?

The active compound is the same, bremelanotide. Vyleesi is the FDA-approved autoinjector for premenopausal women with hypoactive sexual desire disorder; this vial is a lyophilized research chemical and is not approved for human use.

How is the vial reconstituted?

The listing says to add 1 ml (100 units) of bacteriostatic water when ready to use. Bacteriostatic water should be replaced six weeks after opening.

How should it be stored?

Store the lyophilized powder at -20°C. Keep it dry and away from light, and reconstitute only when needed.

What side effects are known for bremelanotide?

Nausea, headache and flushing with red, hot, tingly skin are the common ones. The listing says they are usually mild and last 10 to 20 minutes; the approved drug's label also lists nausea and flushing as frequent.

It is the lowest of the three new listings as of November 5, 2026, at CellularPeptide. With only three stores pricing it, there is little history to judge against, so compare purity documentation as well as price.

One 3 ml vial of lyophilized PT-141. Bacteriostatic water and syringes are not included, so you need to supply them separately.

Our take on the PT141

PT-141 is bremelanotide, a melanocortin receptor agonist studied for hypoactive sexual desire disorder in premenopausal women and sold as a lyophilized research peptide. This vial is 3 ml of laboratory-grade material listed at over 99% purity, with the full sequence and CAS 189691-06-3 stated. It is a research chemical, not an FDA-approved consumer product; the approved bremelanotide drug is Vyleesi, an autoinjector. At $35.00 at CellularPeptide as of November 5, 2026, it is the lowest of the three new listings, so there is no meaningful recent range to compare against yet.
