El Jefe Guerilla is a flexible-dose pre-workout from Xtremis Cartel, part of the popular El Jefe series. It is organised into three matrices – pumps and power output, energy and focus, and absorption – to deliver a complete pre-workout effect. The ’40/20′ reflects its dosing: 40 servings at one scoop or 20 servings at two scoops.
The Pumps AND Power matrix contains citrulline malate, beta-alanine, arginine nitrate (as NO3-T), betaine anhydrous, taurine and VasoDrive-AP. The Energy AND Focus matrix contains L-tyrosine, Alpha-GPC, DL-DMAE bitartrate, theobromine, EnXtra, anhydrous caffeine, Infinergy and caffeine citrate. The Absorption matrix contains AstraGin. As these are proprietary matrices, individual doses are not disclosed.
Yes. Its energy matrix uses multiple caffeine sources (anhydrous, citrate and Infinergy) plus DMAE, theobromine and EnXtra. It is a strong, caffeine-led stimulant pre-workout, although it does not rely on harsher stimulants like DMHA. It is still not suitable for anyone sensitive to stimulants.
VasoDrive-AP is a patented ingredient derived from milk-protein peptides. It is included to support healthy blood flow and vasodilation, helping deliver bigger, longer-lasting pumps alongside the arginine nitrate, citrulline and betaine in the pump matrix.
It aims to deliver strong pumps and power output from citrulline, arginine nitrate, VasoDrive-AP and betaine; clean energy and sharp focus from its caffeine blend, L-tyrosine, Alpha-GPC and EnXtra; and improved ingredient absorption via AstraGin. The flexible dosing lets you scale the intensity to your needs.
Mix 1 or 2 scoops (about 14g or 28g) with water and drink 20-30 minutes before training. Start with one scoop to assess your tolerance; two scoops is intended for experienced users who want maximum intensity.
Moderately. The single-scoop option makes it more approachable than some hardcore pre-workouts, but it is still a strong stimulant product. Beginners should start with one scoop or less to assess tolerance, and stim-sensitive users should be cautious.
It should not be stacked with other stimulant or caffeinated products. It can be combined with non-stimulant supplements such as creatine, protein or intra-workout amino acids, and the single-scoop option leaves room to add a stimulant-free pump product if desired.
As a caffeine-led stimulant product, it may cause jitters, an elevated heart rate, or difficulty sleeping if taken too late. Start with one scoop to assess tolerance, avoid other stimulants, and do not use close to bedtime. If you are pregnant, breastfeeding, stimulant-sensitive, have a medical condition or take medication, consult a healthcare professional before use.
