PT-141 is a potential remedy for the treatment of sexual dysfunction; specifically, male erectile dysfunction. Studies have shown that PT-141 does not act on the vascular system like former compounds, but allegedly works by activating melanocortin receptors in the brain, therefore helping increase ones sexual stimulation. PT-141 is a melanocortin based peptide that has shown effectiveness in clinical studies on both male and female rats. Male rats have shown erectile response with doses as low as 1-2 mgs whereas most female rats have shown positive results with higher doses around 2-3 mgs. While the dosage requirements tend to be higher for female rats, the observable results in female rats tend to be stronger.
