SMART CAFFEINE
Came and stayed
Since it came to me as a gift it doesn't want to leave... I combine it with my Pre workout combo: citrulline, betalanine, creatine...and excellent results. They are easy to swallow and can also be opened without problems and mixed with the Pre Workout. It gives you the boost you need to give it your all... I recommend it.

SMART CAFFEINE
Prefer anhydrous
Honestly, I hardly notice any effect. I like the anhydrous better. However, super good price and perfect presentation in the bottle.

SMART CAFFEINE
A true staple
Affordable. Powerful and a real lifesaver on days when extra drive is needed, in and out of the gym.
Minimum purchase of units!
