Hey guys im fully aware of the catabolic effects of the t3 however i was wondering what peoples experiences are in terms of cardio when using these substances (t3/t4 and clen). Im thinking slow cardio maybe a 4mph walk for 70 minutes a day will be a good method for maximum fat loss and prevention of catabolism.
Also ive heard alot of people say it burns alot muscle but few people have actually said it happened to them so im just wondering if anyone has had any really bad experiences and also if people who have done the same cycle and lost hardly any muscle mass

im 5ft 11 and 16.2% bodyfat, looking to get to 12ish in 4-5 weeks.

cheers guys
