If your chubby, you shouldl earn how to eat first!!!! Diet is the MOST IMPORTANT PART OF BODYBUILDING. If you use those drugs, you will gain, but, you will not be able to keep the mass, even with good PCT, because you don't know how to eat. Second, with a bad diet, you may come out of this cycle with alot more fat gain than you want, and you'll be back here in 10 weeks talking about a cutting cycle, which of course, will also be a failure because you still don't know how to eat. But good news my friend, if you want, I can give you a plethora of diet advice.
