First, DNP isnt something to play with and I wouldnt recommend it as anyones 1st choice for thermogenics.
Second, if you want a thermo, start with an ephedrine based product or
clen.
Third, if BFL worked for you in the past, it can work for you again. Its not the best program out there, but its easy to follow and hits all the bases. The cardio portion of it is probably its best attribute.
Fourth, guys typically can have very lean legs and still have a little gut. Youre not abnormal in that regard.
Fifth,
AAS isnt going to burn the fat for you. It will simply allow you to preserve or add some muscle while you are dieting.
Lastly, I would say to get your eating and training under control before even considering
AAS.
