The Metabolic Nutrition pre workouts ESP and ESP Extreme weren’t exactly the easiest pre workouts to review. But after a month with each, we finally got it all down for you guys.

So, why was it so tough?

Mainly because their label is proprietary-and-a-half. Honestly, this is the worst proprietary formula labeling that we’ve seen in the last 4 years.

But labeling and marketing aside, we’ll lay down the truth so you know what to expect from ESP as well as its grey-market big brother ESP Extreme plus how to best take them.


Quick Review: Metabolic Nutrition’s ESP and ESP Extreme focus primarily on beta-alanine, caffeine, and theobromine. These 3 ingredients encompass basically the entire active ingredients formula. The exact dosages of each, for both ESP and ESP Extreme are unknown due to proprietary formulas. Overall we were not pleased with this pre workout supplement.

Quick Strengths: Powerful caffeine boost in great tasting flavors. ESP Extreme also contains the stimulant DMHA.

Quick Weaknesses: A caffeine shot and nothing else. Moderate caffeine shot for ESP, and a heavy shot for ESP Extreme (though this may just be the DMHA). Not an exciting product.

Best way to take ESP and ESP Extreme: ESP and ESP Extreme are both best taken approximately 30 minutes before exercise. I wouldn’t take either of these products for cardio as heart rate will increase significantly.


Metabolic Nutrition’s ESP Pre Workout Full Review

Energy Effects 5/10

With ESP, energy is the name of the game. Well, sort of… After taking Metabolic Nutritions ESP for a month, we’re still unsure of exactly how much caffeine is in this stuff. Some days it gave us a bit of energy and jitters, while other days it was a total crash. Based on this, ESP only gets a 5 out of 10 in the energy effects department. For greater energy, reach for their website exclusive (non-amazon) ESP Extreme if you’re ok with the stimulant DMHA.

Strength Effects 2/10

Minimal, zero-like, zilch. That’s what we received from ESP in regards to strength enhancement. This product is basically beta-alanine and caffeine.

Endurance Effects 3/10

Again, very little benefit. This pre workout was a total dread for us to be taking. There are notable electrolytes in ESP, however there is so much sucralose, dyes, and fillers that there is no way to tell if the cumulative effects are pro or con.

Crash/Aftermath Effects 6/10

Since there isn’t a ridiculous amount of caffeine in ESP pre workout, the crash isn’t horrendous either. So, ESP squeaks by with a 6/10.

Taste 9/10

On the taste scale, Metabolic Nutrition’s ESP pre workout was quite tasty. No denying that.

Price/Value 5/10

Tasty or not, we don’t like paying $30 for a product that does next to nothing. Maybe 10 years ago ESP would have merit, but not today with the current competition. Just look at our other pre workout reviews for comparison.

Similar Products

The curse is likely the most comparative product on the market. We didn’t like it a lot, however in comparison it is better.

Review Conclusion 5/10 Poor Rating

Overall, we’re really disappointed with ESP pre workout. If we didn’t invest so much time into reviewing ESP and ESP Extreme, we wouldn’t have even wasted the time to post this review. But we are a bit petty and honestly hate this product, and don’t want others to have their time wasted either.


Ingredients in ESP Pre Workout

ESP Ingredient Label
Beta Alanine Citrate – Looking at the ESP label, you can clearly see this “beta alanine citrate”. We’ve never heard of it, and can’t find anything on it. Best guess is that this is a typo on the label.

1,3,7-Trimethylpurine-2,6-dione – This is the chemical name for caffeine. Nothing fancy here. Typically brands use this name to make their products seem more complex than they really are. GAT Nitraflex does the same thing.

3,7-dimenthyl-1H-purine-2,6-dione – Similar to caffeine, yes, but not quite! This is Theobromine, a stimulant commonly found alongside caffeine in chocolate and coffee beans. Theobromine does make a good accessory stimulant to caffeine and its typically a great addition. However we do not know how much is actually in here.

N-Acetyl-L-Tyrosine – This neuro-transmitter promoting ingredient is great for mood and concentration.

Choline Bitartrate – Choline is an amazing ingredient. Even as its less-expensive bitartrate form, its effective.

Calcium Gluconate, Magnesium Gluconate, Potassium Gluconate, and Sodium – Sources of electrolytes.

ESP Vs ESP Extreme

Both labels are completely proprietary, however, ESP Extreme includes the addition of the stimulant DMHA which is similar to DMAA. We prefer not to touch it, but tested it out for you guys. Overall, it aided focus but didn’t necessarily feel clean.


Additional Information

We’ve taken Metabolic Nutrition products in the past, but ESP was just terrible. The first Metabolic Nutrition product that we tried was their Creatine product, CGP (creatine glycerol Phosphate).

We have also had their:

  • Tripep BCAAs
  • and Protizyme Protein Powder

These products were better than ESP, compared to their respective competing markets.
