1st cycle ?????

i am posting this ? for one of my freinds. he just recently lost about 60 lbs over the past year and a half, and is really into lifting ,and he eats very clean and is ALWAYS consistent. he wants to start cycling but still wants to lose a few more lbs of fat. there is no changing his mind on whether he will do the cycle or not. i know he is gonna do it. what im wondering is if he does 400 mg eq a wk for 10 wks and 400 mgs test enanthate for 10 weeks and t-3 and clen throughout. actually the clen will be 2 wks on 2 wks off with an eca in the off part. the t3 will be the last 6 wks. im trying to tell him not to use t3 in his 1st cycle but he is going to do it anyways. what im wondering is if u bros think this is a good idea cause i personally have no experience with t3. im wondering if he can still expect to gain muscle on the t3
