I decided to give PT-141 a shot to help with erections and libido. I'm in my 50's and decided to use it over the weekend when we both had lots of free time to play around. I pinned 2mg which is a high dosage vs. the .5 most people start with. did not feel well until 2 hours later when i got an erection, banged my wife 7 hours after injection. no rise in libido at all all night just random boners that made it hard to pee. final grade: A on the erections but a D for libido.
