Don't take creatine with DNP. When I use creatine I am always pissing, and always thirsty as hell and feeling dehydrated if I'm not drinking a lot. You don't want this while on DNP.
Most people consider glutamine a waste, but supposedly the peptide version is actually usable so I don't know. It wouldn't really hurt you.
Clen can dehydrate you too, so I would advise against it. Some people do mix in clen or eca with DNP to maximize their fat loss, but I think you should run DNP by itself for your first time. You want to see how you react to the drug without adding more shit in. If you still want to use clen with the DNP, just make sure you're drinking a shitload of water.
I ran NYC with my DNP just for energy, and I was fine. Next time I plan to run Clen as well.
