Been taking for 90 days I keep coming back because their Tribulus works for what it’s needed for. I find myself with more energy to do what I need to do as well as relaxed in the right places. Keeps my areas loose and heavier than normal for the whole day. I take 4 caps a day With 1 day break each week. I am 30 years old 165 lbs. I also take it with grapeseed extract to block estrogen safely. I have a lot of energy.
