PT 141/MT2 can be a godsend for guys with ED sometimes. If I take a high-reasonable amount, I can guarantee an erection and ability to get one for hours into the night even if I'm just sitting there reading a book. The main issue is sometimes I'll feel it an hour after injection, sometimes it will take 6-7 hours to really kick in. Also, I experience major fatigue the next day- like I just hiked 100 miles the day before while being shot at. I have trouble getting out of bed until 2. Thoughts?
