chemone makes great products, i am using the t3/clen. the t3 is good, makes you very hot and sweaty all the time, also, you dont need alot , if you think it is underdosed or not getting results, get your diet in check, it will burn fat like crazy if your diet is pretty spot on, something I learned from t3 is that it only helps ,it doesnt do everything for you(ie. relying on it to lean out, while you eat terrible-it wont work like you thought). good luck. if his body does not change, kick up the dosage like alterego said by 25 mcgs/wk, but from my experience, lower is better, and add clen in for the best results.
