ASC Supplements El Jefe Stim Pre-Workout

It should be clear by now that a good pre-workout can take an average training session and turn it into a great one. Honestly, with all the choices available, there’s no reason not to use a pre-workout. If a high-stim pre-workout fits your needs, ASC Supplements El Jefe is the choice for you!


What Is ASC Supplements El Jefe Stim Pre-Workout

This is a high-stim pre-workout that’s based around a simple formula. There’s 7 fully disclosed ingredients. There’s also a prop blend consisting of 10 ingredients. With a prop blend, ingredients are listed by weight. Yet users do not know what the dose of each ingredient is. 


Sure, there’s a total dose for the entire blend. This means you can guess at doses, but that’s it. So why does a company do this? The main reason is to hide their formula. Even though you can see every ingredient, you don’t know how much there is of each one. 


El Jefe is hiding the dosing combination. That means no one can copy it. They can try. They may even come close, but it won’t be quite the same. 


Let’s Look At The Ingredients

Citrulline Malate – 1 scoop = 3.5g / 2 scoops = 7g

This is a 50/50 blend of citrulline and malic acid. This combo promotes pumps and supports ATP production. You’ll find many pre-workouts that use this combo. The downside, and common complaint, is that the 50/50 blend reduces the amount of pure citrulline. In this case, the 2 scoop dose provides 7 total grams. Of those 7 grams, 3.5g is citrulline. The version you prefer depends on your goals. Pure pump chasers want the citrulline. Still, if endurance is your goal, this combo is for you. (1)


Beta Alanine – 1 scoop = 2g / 2 scoops = 4g

This popular endurance ingredient is underdosed at 1 scoop. However, this lower dose eases the tingling sensation users experience with this ingredient. Up it to 2 scoops, and now we have a huge 4g dose. The tingling will be there, but it’s short-lived and harmless. (2)


Betaine Anhydrous – 1 scoop = 1.25g / 2 scoops = 2.5g

A common yet newer ingredient, betaine is an osmolyte that pulls water into the muscle cells. This promotes muscle fullness. Also, it improves power and strength. It’s similar to, and works well with, creatine. (3)


Taurine – 1 scoop = 1g / 2 scoops = 2g

Like betaine, this ingredient is an osmolyte. It also has cognitive benefits, and supports hydration. (4)


Nitrosigine® – 1 scoop =  750mg / 2 scoops = 1.5g

This ingredient has two major benefits. To start, it stimulates nitric oxide production quickly, right with the first use. Next, it’s long lasting. It will promote pumps for as long as 6 hours. (5)


elevATP – 1 scoop = 75mg / 2 scoops  = 150mg

ElevATP® is a combination of ancient peat and apple polyphenols. Studies have shown that it increases levels of ATP. This means elevATP supports improved strength, power, and performance. (6)


JEFE STIM MATRIX – 1 scoop = 1321 / 2 scoops = 3642

Total caffeine = 200mg per scoop

Choline Bitartrate, Caffeine Anhydrous, Theobromine, Eria Jarensis Extract, Juglans Regia Extract, DiCaffeine Malate, Hordenine HCl, Higenamine HCl, Alpha Yohimbine (Rauwolscine), Huperzine A. 


This is a prop blend that covers energy, focus, and mood. There are two sources of caffeine, dicaffeine malate is a slower digesting form of caffeine. The blend of caffeine and theobromine avoids jitters and a crash. For cognitive benefit, there’s choline, eria jarensis, juglans regia, hordenine, higenamine and huperzine. Phew! That’s quite a blend! There’s 200mg total caffeine per scoop, with a huge 400mg per two scoops. 


Black Pepper Extract – 1 scoop = 5mg / 2 scoops = 10mg

Last but by no means least, is black pepper for absorption. 

How Do I Use It?

If you’re a beginner, start with 1 scoop. If you’re used to higher stim pre-workouts, you can jump right into 2 scoops. Either way, mix it with 10-12oz water. 

What Can I Stack It With?

Stack it with a pump formula and a hydration/intra-workout formula. Of course, the intra should have EAAs/BCAAs. If you aren’t already using creatine, the pump formula you choose should contain some.
