I have to agree here with Pat, that at 6-3 you should be at about 220 naturally. You might have a low bf but that does not mean anything because in order to gain muscle naturally it is inevitable not to gain some fat. In reality, if you are a little higher in bf it would be much easier to gain.
With that being said, you would need 3-4 cycles just to get to where you can get naturally. On the juice you ahould be around 250lbs minimum up to 275lbs. That's a lot of weight to gain on steroids.
Not trying to discurage you but give you an idea what to shoot for in the future. Forget about eating lean and keeping a low bf, just eat big to grow then after some good gains try steroids.
