best gains i ever heard of was 85 lbs in about 4 months. now the guy had dieted down for a contest when he started so the first 20-30 lbs. would have come without anything. but still he wieghed 170 for the contest. 4 mo. later he was 255. and by the looks of him he wasnt lying. he was 5'8 245 when i saw him. with 22 inch arms, 30 inch thighs and 19 1/2 inch calves. i dont doubt what he said. he was fuckin huge. his massive gains came from sustanon. dont know the dosage. he said he would go get a drink of water and his friends would tell him he looked like had put on 5 lbs since he left to get a drink. he was growing that fast. not literally but just about. of course he was a freak of nature. some people respond that well to certain drugs. good luck in your quest!
