R1 Burn

Daily Drive, Metabolic Motivation*

Burn contains a formidable blend of thermogenic ingredients including a multi-caffeine combination derived from anhydrous, coffee bean, tea leaf, guarana seed, and micro-encapsulated, delayed-release sources. A single serving of either the powders or capsules delivers the energy equivalent of about two cups of strong coffee.*

I like the energy I get and feel the thermogenics doing it's thing, but the watermelon flavor tastes like watermelon soap. Rare miss in flavor for Rule 1. Would definitely buy again, but different flavor.*

I've tried many pre-workouts and this one is pretty good. For the price it's on par with many of the others. It gives me that boost to get to the gym daily*
