I am 19 years old, would running a testosterone booster (the best seems to be MyoGenX) by itself be useless? For my age will my testosterone actually increase enough to make me want to buy the product. Also if I do buy MyoGenX, can it be used alone or does it need to be stacked or as a bridge between cycles. I am cycle free, but am itching to start, but at 19 I am better off waiting a little while longer. So at 19 years old, will this product do anything, and does it need to be stacked.
