I guess it depends on what type of cycle you're doing. I'm assuming it's a bulking cycle. If you're bf% is a little too high right now, you may wanna do a light dnp cycle to get to a desirable bf level before bulking. On the other hand, if you're bf% is decent, you could wait until post cycle since dnp has been shown to be muscle sparing which is always important post cycle. Or you could just do it pre and post cycle. If you could give a little more info it would be helpful
if you do it before cycle and time it right, you can hit you anabolic rebound right into you cycle, doing it after the cycle will dump the fat gained during the cycle and regenerate you receptors much faster
Anyone who has done a decent DNP cycle followed by an AAS cycle will tell you that you get an immediate BOOST when the AAS are applied (provided a proper front end load toward the end of your DNP cycle is utilized).
DNP right after a cycle is asanine, asanine, ASANINE. You do not lose muscle after a cycle as a result of T3.. You lose gains as a result of reduced testosterone production. Using DNP after an AAS cycle will not help your recovery.
