ya some people have super high expectations for tribulus based on hype/marketing but the old diesel test wasn't bad (haven't tried the new one), i've heard really good things about hypertest (want to give that a try in the next few months) and tribosten worked well. like Big T said, put me in a good mood as well, increase in recovery, small weight increase, oily skin, etc....i think it would be nice to stack with like X-factor.
