PT-141, also called bremelanotide, is a melanocortin peptide. People report using it for sexual desire and arousal.
What is measured
The effect index reflects self-reported libido outcomes among people who already use PT-141, read against their own baseline with a 95 percent credible interval.
What is established
The current estimate is positive, but the interval is wide and the reporting population is still small. We have opened the entry and we are measuring. We have not yet validated it.
What is not established
A wide interval means the evidence does not yet pin down the size of the effect. This entry is in progress. It is not a verdict, and it is not medical advice. We never supply or prescribe.
