erections

curious about using pt-141 when I have sex I lose my erections and I go soft. Wondering if I should start it at .5mg a day and see if that helps. My gf lives with me and she jumps me pretty much every night. So I need advice on that.

I got me some pt-141 and I want to use it for erections and also give it to my wife for more sexual stimulation as she doesn’t orgasm easily and I read this stuff can help I weigh 260 lbs and she weights 140lbs. We plan on taking it 2-3 hours before we do the deed. what would be the best dosage...
