Hell yes. My 2 "cycles" have been lighter than that. There's nothing magical going to happen at that dose tho. Diet, sleep, and training are still where it's at.
Not sure I agree with using at 21 unless you're already an advanced bodybuilder, but it's your call man.
Keep away from Tprop and Sustanon for your first imo. TE has zero sting compared. Don't go overboard with the AIs & SERMs but have them handy. Consider hcg while on. Use only HG of course.
I'd recommend getting FULL bloodwork done before starting, liver, lipids, androgens, estrogens, lh & fsh, igf1, ffa, sugar, cortisol, prolactin, everything you can think of, so you'll have a natural baseline for comparison later.
