Love it!

I love my caffeine pills. I take one about an hour before I lift each day and they woke great!

Absolutely fantastic product

I switched to this brand from the leading caffeine supplement company on Amazon, Prolab, and I have to say the switch has been more than satisfactory. Prolab's quality was inconsistent with varying effects from the caffeine day to day, and their new pill design which is enteric coated makes the caffeine interfere with my sleep way too much by causing the caffeine to release over an extended period of time instead of all at once, which is also bad for workouts when you need an immediate kick of energy. Mutant's caffeine product has been exactly what I wanted. A non-coated pill that works fast at a good dosage with huge efficacy. I take one of these and in 5-10 minutes on an empty stomach I feel 50% more energized. These are a great way to start my day and I will certainly buy from Mutant again. I highly recommend this product to all of the caffeine enthusiasts out there, and for those looking to cut out or don't like coffee / tea. Awesome product! :)
