Frequently Asked Questions
How does PT 141 work?
PT 141 (Bremelanotide) works through the central nervous system by activating melanocortin receptors in the brain. Unlike ED medications that work on blood flow, PT 141 targets desire and arousal directly.
Is PT 141 suitable for both men and women?
Yes. PT 141 is effective for both males experiencing erectile dysfunction or low libido, and females experiencing hypoactive sexual desire disorder (HSDD).
How quickly does it work?
Effects are typically felt within 30-60 minutes of administration and can last up to 72 hours. Results improve with consistent use over the protocol period.
Are there any side effects?
Some clients experience mild nausea or flushing after the first few doses. These effects typically diminish with continued use. All protocols are doctor-supervised.
Is PT 141 hormonal?
No. PT 141 works through the nervous system, not the hormonal system. It does not affect testosterone, oestrogen or other hormone levels.
Evidence and Research
- PT 141 (bremelanotide) is a melanocortin receptor agonist that acts centrally on the nervous system rather than peripherally on blood flow, which is why it can work when PDE5 inhibitors do not (Diamond et al., J Sex Med, 2005).
- A Phase III trial in premenopausal women with hypoactive sexual desire disorder showed statistically significant improvements in desire and distress scores on bremelanotide versus placebo (Kingsberg et al., Obstet Gynecol, 2019).
- PT 141 acts on arousal pathways in both men and women, which is unusual for sexual wellness treatments.
"PT 141 is one of the few sexual wellness tools that works on the brain rather than the blood vessels. It is a useful option for clients who have not responded to the more familiar medications."
