Corleone - ok, u obviously did not read the question bro. he asks what steroid will put on the most MASS/SIZE. neither halo or fina can compare to something like dbol or suspension mg vs. mg. there really isnt an argument there. sure fina puts on some solid quility mass gains and i like it more than dbol but it's more of a drug that will add hardness and change the overall structure of the body. dbol on the other hand is know for quick weight gains and size. as for halo i dont know anyone who has made alot of size and mass from it. if any, it is usually only used for pre contest and powerlifters use it for it's effect on agression in someone and strength gains w/out adding alot of weight if any so they can stay in the same class.
