i originally ran this clen(gomeisa labs) with t3 so i couldn't 100% say if it was legit or not. but after taking a break and running it a second time without the t3 i can confidently say this stuff is legit. took 40mcg off rip to really see if i feel it and hands were shaking like crazy, checked my resting pulse and it was sitting at 95, also was sweating all day and during workout i was drenched. good stuff
