I thought I had taken strong tribulus, but this product makes the other one look weak. Working out, I have been pushing up new weights all the time. I have sometimes been amazed and confused at how much I am putting up. I recently benched 20# more than I was before, and it didn't phase me. So I put on another #20. I was pretty sore, but this seems to reduce the duration of soreness quite a bit. Unless I am really pushing really hard, I don't have DOMS anymore.Again, I review this with a warning. If you have enough testosterone already, at the very least ease into this. I am confrontation seeking and flirty normally, this pushes me into overdrive. Whatever you do, don't take their recommended max of 6/day right off the bat. I take 2-3/day and it is more than enough.To finish, this product I was so pleased with that I am now on subscription. First product I have kept on there, and it will stay there for a while.
