My Experience with El Jefe Pre Workout
I have had the most enjoyable experience with El Jefe and it is become one of our favorite pre-workouts. Its effects are an amazing balance of euphoria and energy without any negative side effects.
A full serving of El Jefe is 2 scoops, I’ve taken 1.5 scoops and even 1 scoop with an awesome experience. It is probably best to start at 1.5 scoops to assess tolerance and that will give you 30 servings instead of 20 servings.
El Jefe kicks in pretty quickly, probably within 20 to 30 minutes. Energy, focus, and mood elevation were all apparent by that point.
From there, I had really solid energy and an excellent mood for the remainder of my two hour workout. I didn’t feel jittery or tweaked out, but definitely felt dialed in and focused with a happy mood.
I cruised through my workout and even did a few extra sets of accessories because I was feeling so good.
The best part, in my opinion, is how smooth El Jefe feels afterward. There is no noticeable crash effect. Mood and energy stay upbeat!
All in all, this was a great experience. I was pleasantly surprised by El Jefe, as I was a bit turned off by its proprietary blend ingredient label (one of the few downsides it has).

El Jefe Flavors

We were sent samples of Peach Rings and Sour Gummy. They were both amazing, no issues whatsoever.
Some of these strong pre workouts have bad flavors but this one was great.
El Jefe Ingredient Label
This breakdown of the ingredient label will not include the dosages of each ingredient because El Jefe uses a proprietary blend formula. This means it lists each ingredient, typically in descending order by amount, but doesn’t disclose the amount of individual ingredients.

Citrulline Malate (2:1) – 7 grams
Citrulline is one of the best-researched pre workout ingredients, consistently demonstrating increases in power and nitric oxide alongside decreases in fatigue (Examine).
When citrulline is bonded with malic acid it futher aids in athletic performance.
7 grams is a clinically effective dosage.
Beta Alanine – 4 grams
Beta alanine has consistently shown to support muscular endurance and can act as an a lactic acid buffer. Saturation of 180 grams (beta alanine) is required to reach to achieve these benefits, but 4 grams is in line with recommended dosages.
Betaine Anhydrous – 2.5 grams
Betaine Anhydrous is included in pre workouts to help with power output. It is an osmolyte, meaning it pulls water to the cells.
2.5 grams is within the range of recommended daily dietary supplementation on Examine.
Taurine – 2 grams
Taurine can aid in hydration, muscle pumps, and may act as a booster to anti-oxidant defense systems (Examine).
One of Taurine’s main jobs is to help regulate your body’s electrolytes. By doing this, it may improve endurance, and thus enhance performance. Other studies indicate that supplementing with Taurine can lead to increases in strength and power
2 grams is a solid dosage of taurine to achieve any effects it has to offer.
Nitrosigine – 1.5 grams
Nitrosigine is an ingredient that helps increase nitric oxide levels, muscle size, and mental acuity.
It is a patented complex of bonded arginine and silicon that has been scientifically proven to enhance performance by increasing NO (nitric oxide) levels over each ingredient tested: Arginine AKG, Agmatine Sulfate, Citrulline Malate, L-Arginine, and Citrulline. Nitrosigine is also a scientifically substantiated ingredient with over 28 studies showing efficacy and safety.
Nitrosigine is one of the most effective ingredients on the market for enhancing your pump.
In a study of Nitrosigine vs. Placebo, the Nitrosigine group achieved a 2.3x larger muscle pump than the placebo group.
1.5 grams is a clinical dosage of Nitrosigine.
ElevATP – 150 mg
This is a proprietary blend comprised of ancient peat and apple extract that is shown to increase ATP, leading to increases in maximal power output (source).
Research has indicated that oral supplementation with exogenous ATP is unreliable for increasing ATP levels since it breaks down in the gut. elevATP is unique in that it naturally helps ourselves produce our own ATP the way nature intended. elevATP is NOT exogenous ATP, but an ingredient that helps our bodies provide higher levels of ATP via its own internal mechanisms. Due to this, elevATP promotes non-stimulatory energy from our body’s own mitochondria.
150 mg is a clinical dosage of ATP.
Choline Bitartrate (Prop Blend)
Choline is often included in doses ranging from 1 to 2 grams to help boost mental focus as a nootropic. However, it is often included in Alpha GPC form for this purpose and Choline bitartrate may not be as effective for nootropic purposes (source).
Caffeine Anhydrous – 300 mg
Caffeine anhydrous is the typical form of caffeine, well known for increasing energy, power, and focus.
El Jefe contains 300 mg of caffeine anhydrous, which is a solid dose.
Theobromine (Prop Blend)
Theobromine is a stimulant that is sort of a “caffeine light” ingredient.
Eria Jarensis Extract (Prop Blend)
Eria Jarensis (N-Phenethyl Dimethylamine), is a stimulant and neuromodulator on the Central Nervous System (CNS) and provides several mental effects including powerful focus, energy and an increase in mood.
Eria Jarensis Extract provides a variety of mood boosting and cognitive enhancing effects for the consumer. This is directly caused by its ability to increase noradrenaline and even dopamine concentrations in the body. When these hormones are increased in the body, the user will have a sense of alertness, focus and concentrated attention.
This ingredient is provides a sense of euphoria that is quite pleasing.
Juglans Regia Extract (Prop Blend)
Juglans Regia (the real DMHA) is a naturally occurring form of DMHA extracted from the bark of the English Walnut Tree. It is a powerful psychoactive mental stimulant that increases mental energy, focus and a powerful increase in mood.
Looking at it from a molecular level, it is similar to DMAA, known for boosting energy, focus, and mood.
Di Caffeine Malate – 100 mg
This is the “extended release” version of caffeine, which helps extend the effects of the pre workout and provide a smooth “come down” instead of a rapid drop in energy, which can occur with large doses of caffeine anhydrous.
Citrus Aurantium (Prop Blend)
Citrus Aurantium is a stimulant that is often included in recent “nootropic” products
Nelumbo Nucifera (Prop Blend)
Nelumbo is thought to have similar mechanisms to ephedrine, which has led to usage as a fat burner.
Alpha Yohimbine – 1.6 mg
Alpha Yohimbine, also known as “alpha yo,” is a polarizing stimulant. Some individuals are particularly sensitive to alpha yohimbine and will always avoid any pre workout containing it. Common negative side effects can include anxiety, headaches, chills, sweating, frequent urination, and increased blood pressure.
Personally, I did not feel any of these negative side effects with El Jefe, so I don’t think the dosage of Alpha Yohimbine is too high. I have felt chills and some anxiety from high doses of Alpha Yo, so I am not immune to them, but El Jefe did not give me any of those side effects.
Huperzine A (Prop Blend)
Huperzine A is a cholinergic that acts as a cognitive enhancer.
Conclusion
El Jefe impressed me and it is a pre workout I’d recommend. It is strong, but not insanely strong, which is honestly all I need most days.
No jitters and no cracked out feelings. No feeling like death.
If you’ve never had a strong pre workout before, El Jefe will be more than enough.
If you’re a grizzled pre workout veteran, this hits the spot 100%
El Jefe is one of the most powerful high-stim pre workout that delivers euphoric energy and long lasting focus.
