@fola1985 Test boosters are supplements that aim at increasing natural testosterone production.
Steroids (mainly) replace your body's natural testosterone.
You're too young to even think about this crap. At teen years testosterone and growth hormone are naturally very high with a quality diet and training + no smoking or drinking
If roids: It will because when you get off them your natural test production will not work for like 3 months and you're risking health side effects you wouldn't have otherwise, depression, and longer term natural test production shutdown
