Throughout highschool until I decided to take this crap Twinlabs Mass crap ((Amazon.com: TwinLab Amino Fuel 1000 Body Building Amino Acids, Mega Mass, Tablets, 250-Count Bottle: Health & Personal Care) something similar to that at least) my senior year i was 135 lbs never over never under. I took that shit because I thought i wanted to get big, and i did get up to 150s because of it, but it started to hurt my heart so I stopped after 1 month. I have also taken creatine on 2 occasions for 1 month each time, but stopped because i just started to feel very tired and sluggish. Now i'm on nothing and my weight yo-yos from 140 to 153 depending on what kind of shape i'm in (153 when i'm in shape). My question (finally) is do you guys think that if i never took that crap i would still be 135 or is my weight gain due to getting older and "filling out?" It's been bothering me ever since i stopped, which was about 4 years ago, so i would appreciate some feedback. thanks a lot.
