ASC Supplements El Jefe Pre-Workout Review

This is our full ASC Supplements El Jefe Pre-Workout review.

ASC Supplements have been on my radar for a while, and coincidentally they reached out to me a couple of months ago and asked if I’d like to review some of their products.

I was sent four products, as follows:

  • El Jefe Pre-Workout
  • Sicario Stim-Free Pre-Workout
  • Demonio Stim Thermo Fat Burner
  • Caliente Non-Stim Fat Burner

I’d heard some great things about their pre-workout range and was excited to try them for myself.

In this article, I’m going to be reviewing the El Jefe pre-workout.

Let’s get into the review…

Important Information

El Jefe Pre-Workout Overview

Before we get into the big stuff like the ingredients, prices, flavors, and effectiveness; let’s quickly cover some important information on servings, product weight, and potential supplement stacks.


Tub Size/Servings

A single tub of El Jefe has a net weight of 434g and includes either 40 or 20 servings depending on whether you choose the 1 scoop or 2 scoop option.

Scoop Size

A single scoop of El Jefe weighs 10.85g, which would equal 21.7g if you were to go by the 2 scoop supplement facts panel.

Suggested Stacks

There aren’t any suggested stacks for this product from ASC.


El Jefe Ingredients/Supplement Facts

El Jefe Pre-Workout Ingredients and Supplement Label

There’s a total of 17 ingredients inside the El Jefe pre-workout. They provide supplement facts for both 1 and 2 scoop servings. We’re going to be reviewing these ingredients based on the 2 scoop dosage.

Here’s a full breakdown of El Jefe’s ingredients and dosages:


Citrulline Malate 2:1 – 7000mg

Citrulline is one of the most common ingredients used to help induce muscular pumps.

Most companies will either use pure l-citrulline, or citrulline malate 2:1. The clinically effective dosage for l-citrulline starts at around 3500mg to 4000mg. El Jefe contains around 4666mg of L-citrulline, which is an impressive dosage.


Beta-Alanine – 4000mg

Beta-Alanine is naturally produced in the body, however, most people don’t produce enough required for intense physical exercise. However, it does require a loading phase of 6g per day for 28 days, which means you’ll need additional supplementation alongside most pre-workout products.

3000mg-3200mg is a standard dosage used in pre-workouts.


Betaine Anhydrous – 2500mg

Betaine Anhydrous is used in pre-workouts to reduce muscle fatigue. Further research is still required to ensure the accuracy of this statement.

2000mg is the dosage most pre-workouts will contain, with 2500mg being considered an optimal dosage.


Taurine – 2000mg

Taurine is an ingredient with mixed opinions when it comes to pre-workout supplements. although it helps regulate many bodily functions, it also has anti-inflammatory properties, meaning it could actually reduce the ‘pump effect’ most people inside the gym are seeking.


Nitrosigine – 1500mg

Nitrosigine is a patented complex of bonded arginine silicate. It’s had over 30 studies done to test and prove both its safety and efficacy. Nitrosigine has been shown to promote NO2 production and improve blood flow, focus, and energy.

1500mg is a typical dosage.


ElevATP – 150mg

ElevATP is a natural combination of ancient peat and apple polyphenols, which has been clinically shown to increase levels of endogenous ATP, supporting improved strength, power, and performance.


Jefe Stim Matrix – 2642mg

One of my biggest pet peeves when it comes to supplements is the use of blends, matrixes, or complexes that don’t allow you to see the individual dosages of each ingredient.

This is one of the main things I don’t like about the El Jefe pre-workout.

However, I understand that it’s often done so that competitors don’t swipe the brand’s formulas.

The Jefe Stim Matrix includes 10 different ingredients for a total content of 2642mg.

Here’s a full list of the ingredients:

  • Choline Bitartrate
  • Caffeine Anhydrous – 300 mg
  • Theobromine
  • Eria Jarensis Extract
  • Juglans Regia Extract
  • Di Caffeine Malate
  • Hordenine HCL
  • Higenamine HCL
  • Alpha Yohimbine (Rauwolscine)
  • Huperzine A

This matrix is designed for energy and cognitive enhancement purposes, with 300mg of caffeine anhydrous being the key driver. It also incorporates Di Caffeine Malate, which means there’s 400mg of total caffeine inside a 2 scoop serving.

I would assume that Choline Bitartrate is the ingredient with the most content inside this matrix, possibly just under 1000mg. 

Overall, the Jefe Stim Matrix definitely packs a punch, and with ingredients like Huperzine A, Choline, and 350mg of caffeine, it should provide the energy and focus needed for an intense workout.


Absorption Matrix

The last ingredient is black pepper extract, which can help boost the absorption of all the other ingredients.

  • Black Pepper Extract – 10mg


Flavor Options

ASC Supplements El Jefe Flavor Options

El Jefe is currently available in four different flavors, and I think their flavor selection is pretty much spot on.

Here’s a list of all the current flavor options for ASC Supplements El Jefe:

  • Peach Rings
  • Orange Creamsicle
  • Sour Gummy Bear
  • Tiger’s Blood


Orange Creamsicle

I was sent the orange creamsicle flavor to try and out, and boy did it hit the mark. Both the smell and taste are amazing. I’ve found myself using this pre-workout regularly because of the flavor, even though I have at least six others sitting on my desk that need reviewing.

Now we’ve covered all the important information about the product itself, let’s talk about the cost.

The price of El Jefe is $54.95 on the official ASC Supplements website. They market it as a 40/20 serving count, similar to the likes of Gorilla Mode. The price is a little high given the total quantity per serving.

Where can you buy El Jefe?

You can buy El Jefe direct from ASC Supplements. It’s also available from other supplement retailers such as Nutrition Faktory.



Whilst I have no idea as to the exact dosages inside the Jefe Stim Matrix, I could definitely feel the effects. I was locked into my workout and felt impressive levels of energy and concentration.

This was the highlight of El Jefe.

The pump was also impressive, but I felt that the cognitive aspect of the pre-workout overtook everything else.

This is a high-stim pre-workout supplement, and I could definitely feel it.


Frequently Asked Questions

This section is dedicated to covering some of the most common questions people have when it comes to El Jefe.


Q: How much caffeine does El Jefe Pre-Workout contain?

A single scoop of El Jefe contains 200mg of total caffeine content, with a 2 scoop serving containing 400mg. This is achieved through a combination of caffeine anhydrous and di caffeine malate.



So where does El Jefe stack up as a pre-workout?

Overall, I’d rate El Jefe Pre-Workout highly.

The biggest benefits of El Jefe are the effectiveness of the stim matrix, as well as the clinically effective dosages of l-citrulline, betaine, and NitroSigine. This is of course only relating to the 2 scoops serving size. A single scoop won’t give you the clinically effective dosages for most ingredients.

The downsides are that you can’t see the exact dosage for ingredients inside the Jefe Stim Matrix, and it might be slightly expensive given the total content per serving.

Either way, it’s effective and worth a try.
