Anyone Using T100?

Hey everyone. Im 19 years old. Ive been hardcore training/eating for the past year. Ive made awesome gains. Ive gained 20lbs of mass in the last year. I did a 8 week cycle of T100 a couple months ago. I didnt notice a big increase in strength or weight while on it. I just had a good pump 24/7. At 19 years old should i not even be messing with any of this stuff? I dont want anything messing me up in the long run.

thanks guys

you can still do alot of growing naturally without steroids...at 19 your test levels are as high as they'll ever be....just stick to a good work out and a really good diet and you'll see great gains
