## FAQ

### What receptors does PT-141 (bremelanotide) bind to?

PT-141 is a melanocortin receptor agonist that binds MC3R and MC4R, receptor proteins in the brain linked to central pathways studied in arousal and desire research.

### Is bremelanotide FDA approved?

Yes. Bremelanotide is FDA-approved as Vyleesi for acquired, generalized hypoactive sexual desire disorder (HSDD) in premenopausal women. All other uses are off-label or investigational.

### How do you reconstitute PT-141 lyophilized powder for research?

Add bacteriostatic water to the vial and divide the vial's milligrams by the milliliters of water added to get concentration in mg/mL. Example: 10 mg + 2 mL = 5 mg/mL.
