Androtest uses a cyclodextrin to enhance absorption of the prohormone (Cyclo 4-AD), which converts directly to testosterone. Every hardcore bodybuilder knows that nothing comes close to testosterone when you need rapid muscle gain. Nanodrol, on the other hand, is the sequel to Ultradrol which has been proven to deliver rapid strength increase, which along with the size you are going to get from Androtest, will turn you into the ultimate weights-destroying machine.
