Results depend on compound and diet. If DMZ produces Superdrol like results you should expect around 20-30 lbs on the scale. Superdrol was also the best compound (since they banned tren) for burning off fat while building muscle. You probably won't look like Zyzz off of 1 cycle, I think by the end he was blasting and cruising and already had a few cycles in him. You won't look like Ronnie or a roided out guido off of 1 cycle.
You will notice a complete physique change for the better. I ran Hdrol in Jan and went from 185-210 on the scale and looked completely different. I don't know about DMZ but superdrol and the other designer steroids it was easy to keep gains if you ate and ran pct. The side effects suck, hdrol is easy on the hairline and outside of a very little shedding I didn't lose any hair. They are all hard on the liver and will raise blood pressure so you need hawthorne berry and liver supps. I had some back pumps and dry joints but taurine and fishoil helped with that.
It's best to run it on a bulk/recomp, because you want to maximize gains while on the compound, the compound will also burn fat. If DMZ acts like Superdrol it is extremely carb hungry.
PCT is a toss up, run a full pct like you would with a real steroid, on SD they suggested 6 week PCT, hdrol was only 4, DMZ is probably in the 4-6 week range. I used a Liquid Nolva research chem but didn't really like it, I was going to research more about Torem for my next cycles pct.
