Had to discontinue use of this stuff after 7 days, it made me feel progressively more and more horrible and tired, plus kidney pains! Then I got a very bad cold and sinus infection. It felt like I was takeing an EXTREMELY high dose oral cycle of actual gear. I don't think I will be taking any more orals - legal or illegal - from here on out! I do not reccomend this product at all unless you are going to use an extremely low dose (like 1 pill a day) and then what's the point anyway.
