Hey guys,
I'm 19 years old going on 20 and I am only 5'8 145 pounds. The reason I am this light is because of years of wrestling and keeping my weight down. Now that I'm done with wrestling I want to get big. Ive done a lot of research on diet and training. But I recently got some Testo-Jet L/A NRV. I'm deebating on whether or not to take it. I know I probably should wait til Im 21 but if I do decide to take it what is the best way I should go about it?
