This is a preference imo. All 3 of those are known to be some of the best. Dbol is dbol though if it is accurately dosed. I have used reforvit, body research (10mg blue hearts), and pink tais by british dragon. Of those I like the blue hearts best. I now have some pink tais by british dispensary (with snake on them) and I have some russians. I will see how good they are.
