Ever heard of the word G.E.N.E.T.I.C.S. ? It's has the greatest influence on your body's growth. Much more influence than TEST/DECA/EQ/TREN/WINNY and ANADROL together.
For exmaple my chest will NEVER EVER grow EVER why? Because that's the way it is.
hmmm...you are smaller than I thought you would be but you have some quality muscle. Need to start hitting the incline bench a little more. The tren gave you some good vascularity, that's for sure. Good job.
