Lots of things affect metabolism.
Cortisol, T4/T3 and TBP, B12, your activity levels or total daily energy expenditure vs your caloric intake.
Macro balance can affect it also.
There are training methods you can use to increase metabolism (increase mitochondrial density) and diet...
Rapid Refuel by Muscle Sport International is by far the best I have ever used. 2:1 ratio of proteins to carbs. Has joint supps, electrolytes, Aminos and more.
It’s a solid complete product. I have yet to find a comparable product all in one.
Somatomax rocks. Wish it didn't have aspartame though.
Lemon drop is good. They used to make watermelon but I never see it anymore.
That banana flavor is gawd awful IMO
Take 1 scoop with some DMAA based stim preworkout and it's like mild extacy
Ok in all seriousness it really depends on the intent of the workout. Time of day. Type of workout. And duration of workout.
Aminos with Creatine is most critical in most situation.
Carbs may or may not be needed.
