Im going to give my opinion on insulin, my experience on insulin is nothing to that of the guys who have been using gear for decades here, so Im not asking anyone to hold my opinion of any value, but I do believe what I am about to say. Insulin, (assuming you respond to it) even a little bit ...works. . You won't notice changes "in the mirror" like you will on tren,...other people will let you know how fucking big your getting. You just wont be impressed with yourself in the mirror up close...... and insulin and gh ruins a physique up close....but makes it impressive from far away. You will look fucking huge to that person looking at you across the gym, but when your up close....you won't freak them the fuck out. A guy who builds his physique on anabolics, is generally the opposite. they get more impressive the closer you get.....
