I have..(I don't ever post by the way, only when I see something "new"). I used 5ius with 20mg of gw and clen on and off. Weightloss was almost hard to control, and this is not a good thing. This, with contest dieting and just being "ugh" from 20 weeks of dieting, made me lethargic. Kind felt like a high dose of M1T (back in the day). It's funny, I had to be careful when the dose was taken. Due to the uncoupling nature of gw, it felt like a low dose of DNP. I had a heck of a time ridding water…(uncoupling)??pre show. I do like gw, just haven't figured out the best way to run off-season. On a side note, I ran s-4 with it…yellow tint in vision came after a month of using. It's just now getting back to normal.
