Would it be safe to say that even with gear, genetics play the biggest role in how you grow? My last cycle I ran pretty high doses of test, and moderate dose of tren (150mg prop ed/50mg tren ed -11 weeks). Even with those doses my body can't seem to grow too well. I don't think my body is made to be at a high weight. I have to work my ass off to maintain what I have right now and it's not even that much. I'm 5'8, 190 lbs and about 9% bf. I have a real hard time getting any higher with or without gear.
