can anyone besides 250+ bodybuilders even use 2 grams. i would think that the body could only use so much and whatever isnt used will convert into estrogen, producing more sides. anyway, most vials come in 10 or 20ml vials these days, say you have 20ml at 250mg/ml for test e, that bottle would only last you 2 and a half weeks. just like protein intake, its proven that your body can only use so much protein, and any extra protein will just go to waste or convert to fat (its hard to convert protein to fat but its still possible).
