Bremelanotide (PT-141) is a synthetic peptide that simulates melacortin (the chemical responsible for pigment in your skin). One of the
side effects is extra sensitivity in the genital region,
and erections in men. I have obtained the highest quality erections from this compound, far greater than any combination of Viagra, Cialis, or Levitra. If you have been cleared by a urologist as not having a pumping problem, and the doctors suspect it is psychogenic ED, then you need to try this peptide.
