DMAA is a very harsh stimulant and will wreak havoc on your cortisol levels and adrenal cortex - counter productive to your fat loss and muscle building goals.
Supplement with n2slin instead. It has no stimulants and won't raise cortisol levels. It is a nutrient partitioner and will help increase insulin sensitivity in your muscles.
Another thing you could look into is SARMS - particularly the SARMS triple stack. They provide tremendous endurance, recovery and fat loss benefits with minimal side effects. After the SARMS triple stack, run a mini PCT. 4 weeks of the following:
clomid at 25mg/day
nolvadex at 20mg/day
HCGenerate ES at 5 capsules/day
n2guard at 3 capsules/day
Both of these options will provide much better results with MUCH less side effects.
