Is PT-141 the same as Bremelanotide?

Yes. PT-141 is the research name for bremelanotide, the active ingredient in the prescription drug Vyleesi. The vial here is a laboratory-grade peptide, not the approved injector.

The vial arrives lyophilized and must be reconstituted with bacteriostatic water before use. It is labeled for laboratory research, not for human dosing.

What side effects are known?

In clinical studies of bremelanotide, nausea and flushing were the most common effects, along with headache and injection-site reactions. Nausea was the main reason people stopped treatment.

How does it differ from Viagra or Cialis?

PT-141 acts on melanocortin receptors in the brain to affect desire, while sildenafil and tadalafil act on blood flow. It is not a substitute for either and is not approved for ED.

It is the lowest of the two stores listing it new as of November 5, 2026. Compare purity testing and vial size before treating it as the better buy.

How should the vial be stored?

Keep the lyophilized vial refrigerated and dry until reconstitution. Once mixed, store it cold and use it within the period your protocol specifies.

PT-141 (10mg) is a lyophilized vial of bremelanotide, a melanocortin receptor agonist studied for low libido and sexual arousal disorder.

The best new price is $40.00 at Biofusion as of November 5, 2026, the low end of the two-store range.
