Honestly dude, diet can get you that same mass if you do it right. Steroids and a good diet.. easily. How long it will take you to get there will obviously vary from person to person.
those cuts are very tough to get unless you're naturally sculpted and toned and all you gotta do is put on good weight..honestly thats where your gear comes in...im not expecting to look any less than that by the end of this 12 week cycle
