Have you used DNP before? If not, I would rethink using it. It will rob you of ATP, leaving you flat/deflated, tired, and weak. The heat factor alone is very uncomfortable. Personally, I would never suggest it for most people, ever, because of how dangerous it is, This stuff is not good for your body and too much can kill you.
If you are going to use it, the dose you have is good but I would never suggest running it for 7 wks. Put it this way, I know a lot of people, and none of the competitors I know would use DNP for 2 months. 2-3 wks is plenty, and you'd take it after you are already very lean, just to push a little further. After you are doing a lot of cardio, lets say 2 hours or more, you risk losing leg size and having your wheels look stringy on stage. At that point, a small dose of DNP for 2 wks will help you strip off that last bit of remaining fat, without having to to do more cardio.
If you are rethinking DNP at this point, I wouldn't blame you. If you want to burn some serious fat, look into clen and possibly T3. Naps has a good selection of these drugs and they are solid fat burning aids and you can get to low single digits without as much drama. If you want to turn it up a little more, swap out the clen for helios.
BTW, If you take a look at other posts here, you'll see I've gone into great detail about clen use. You don't need to cycle off afer 2 wks. If may down regulate some but it won't stop working. I'd start with 40mcg ED and add 20 mcg, every 2 wks, capping it at 120mcg, then staying there for the rest of the cycle. 3 wks after you start, I would add the t3 at 25mcg and then every 2 wks, add 12.5mcg, until you reach 75mcg. Then ramp the t3 back down by 12.5mcg every few days, to come off of it, over the last couple of wks of the cycle. Clen on the other hand, does not need to be ramped down.
