Train for at LEAST 6 months, and see how your progressing. I've been training 3 years and only just began my first cycle yesterday. Over the 3 years i've had a lot of natural growth and only just reached certain pleateus (not saying i cant break them naturally).
Just gotta be patient. After 6 months even, people won't advise you start on
AAS, but your going to do what your going to do
