This sounds very much like another post i just commented on so il say the same thing.
Deca only - erecticle disfunction.
Proviron - Use for hardening NOT PCT as some people think.
If you want to get big use Synthol. Lots of Synthol. You are messing with serious sh*t that will (and i mean that) mess you up if you do it wrong. You need to eat right and train right. You cant go eating big macs.
Sort yourself out and DYOR before you come and post here again.
