Product Review: USP Lab’s Jack3d Micro

Pre-workouts are great for focus and concentration or a jolt of energy before you go to the gym. USP Lab’s Jack3d Micro is their new formula does not have the 1, 3 dimethylamylamine, also called DMAA in it because it has been banned for potential health risks. If you’ve taken the original formula, you know that hulk-like feeling you get.

If this is the first pre-workout you have ever had, you should have some decent focus and energy from it. If this is not your first pre-workout you’ve taken, you will not notice much of a difference. Your body seems to build a resistance to these pre-workouts which will make them seem less effective.

Overall I give this product a 3/5. I will admit when you review a pre-workout, they are a different monster because you have to take into account tolerance of pre-workouts and other factors.

I gave this pre-workout a 3/5 because I’ve tried many stimulants and this one falls short. I can’t say for certain it is the ingredients used or my tolerance, but I have had a few really intense workouts with amazing focus from this product.

On the other hand, I have taken 3 or 4 scoops of this stimulant and I did not get any type of charge, in fact I felt a little sluggish and sick to my stomach. I only felt sick to my stomach because I took twice the recommended amount; I’ve never had an upset stomach with this product when I took the recommended dosage.

If you would like to purchase online, seems to have a great price. Most shops like Vitamin Shoppe or GNC should carry it.
