It’s a good compound the one big thing is hair lose! If you are prone to hair lose don’t use it. Your hairline will recede faster or your bald spot will get bigger. Other than that it’s good especially if you are lean.

You can stack any thing and any combination you want but. But the DHT have less water retention and less estrogen conversion the testosterone and Nandrolone (Deca and NPP) will convert to estrogen and make you hold more water.
It’s best to use one compound from each branch if you are going to stack. My favorite is Test E Primo (if I’m lucky it’s mostly mast or test) NPP and Proviron.
So at least I am on the right track. That’s what I did if I understand correctly, right? I’ve been trying to do as much research as I can. The only thing you don’t really find much on is doses
