Is this good to burn fat?
Grains and mitoburn are fat burners. They work great, but just like every other fat burner, if your not in a calorie deficit and doing cardio your flushing money down the toilet, there's no magic pill.
I like a supplement that contains the 2 things I mentioned in combination with Injectable carnatine and a little yohimbine in the morning "only if doing fasted cardio"
If you don't mind giving yourself a little sub q shot 2-3× day look into sr9009, the oral version doesn't work in my opinion, it's like 1% bioavailable vs. The Injectable being 99%
