You are definitely too young and also not in the right condition... thats a huge discrepancy just in you saying 15-20% on body fat and that alone is...
if you want something mild with little to no side effects then simply do not run steroids and use sarms... every steroid is going to carry more side...
i turn down paying clients that want advice on clen... DO NOT use clen whatsoever... you should watch my video on clen side effects and alternatives...
i would go with 350 mg of test per week and 500-600 with mast... theres no need for more than that... anavar or winstrol would make a great addition...
so are you saying you want to run a pct then start trt? you should not use trt if you do not medically need it... i guess its a little unclear to me...
