Best Pre Workout for 17 year old
I'm 17 years old, 150 pounds, athletic, i have been working out regularly for about 2 years now and lately with school and work i just feel tired when i work out, not my muscles being tired, but my brain and body if you get what i'm saying. i want to take a pre work out that is good for someone my age and will boost my stamina, strength, endurance, ect. i have heard that jack3d is good (but it has creatine i don't think i should be taking that) and i just read about AN Amino Energy. I only take whey protein and Multi Pro 32x after my workouts. If anyone has any suggestions about a pre workout i should take please let me know thanks.
