Guys,
Just to add my experience with Tribulus----last year, I thought I'd try this stuff out, seemed to have a lot of hype. Well, after being on it a month, I seemed to have an increase in libido (giddyup), and I was breaking out a tad bit more, but that's about it. During this time, I convinced my doc to draw some blood, testing a range of things, one of which was my free testosterone. Well, surprise, surprise, smack dab in the middle range, where I've always been.
So, conclusions? Libido enhancing, maybe. Anabolic? I'm thinking no. I'll save my money on this one.
