Xtremis, formally ASC Cartel, is back with a reformulation of their daily driver pre-workout El Jefe Guerilla edition. This is the “baby brother” pre-workout of the OG El Jefe pre-workout.
This product features highly efficacious and clinically dosed ingredients, providing excellent performance inside and outside the gym. I recommend this for anyone looking for a daily pre-workout but has a higher caffeine tolerance, as it contains 462.5 mg.
Thank you, Jake from Nutricartel, for sending this full product for review![Read more…]
