What is PT-141.?

PT-141 is also known as Bremelanotide and is most known for its ability to treat sexual dysfunction in men and women. It is a derivative of Melanotan 2. It’s a synthetic peptide blend, as it isn’t naturally produced in the body like growth hormones are. PT 141 was developed from the Melanotan 2 hormone which is known to help darken pigmentation of the skin. It has often been linked to individuals treating sexual disorders (including ED or hypoactive sexual desire in women).

PT 141 is a nonselective agonist of the melanocortin receptors. It’s been primarily used and tested for treating sexual disorders, however, because of increases in blood pressure of test subjects, these studies were halted by the FDA. It was later turned into an injection form, and testing continued in treatments for female sexual dysfunction in recent years.


– Sub Q (men and women) 2mg dose, 1 hour before sex it is recommended to inject 1mg for test dose, then add 1mg more 30 minutes later.

Titration may be needed to achieve the desired response. You do not want to exceed 2mg in 72 hours. Everyone’s response and timing of the drug is different per person.
