Not sure if it's a proven thing or not and it could be quite dangerous but drinking a glass of grapefruit juice everyday may increase the absorption of them. Grapefruit juice does something along the lines of allowing the compound to cycle though the body longer therefore allowing more to be absorbed. I did this on my last beastdrol cycle, I got good gains and no major sides. But use caution if you do this because taking grapefruit juice with some medications can cause severe or fatal problems!!!
i've heard both sides of the debate.
i've also heard taking something when your stomach has grapefruit juice in it pretty much kicks the shit out of what you are taking.
i don't know what to believe to be honest.
