You can’t have a pre-workout without advertising its energy benefits. Well, technically you can but 9 out of 10 pre-workouts on the market today all contain stimulants.

One of the most popular stimulants of all time is caffeine, and it’s next to impossible to not see it on any popular pre-workout supplement.

Caffeine is cheap, portable, and simple to use. And we think Nutrex realized this when they formulated Lipo-6 Black Training, their latest spin on the Lipo-6 series.

The most glaring ingredient on the formula label is caffeine and its 425 mg total dose. There are of course other ingredients at play, but none of them seem to bring more attention than this stim powder.

Did Nutrex do the right thing by upping caffeine to the maximum or will this backfire on them? Let’s find out!

Who Makes It?

Lipo-6 Black Training is sold by Nutrex. Nutrex has been a popular name in the industry since they started operations in 2002. They were the first supplement company to make use of liquid encapsulation which were said to give a multi-phase effect, essentially having two capsules in one [1].

Their most popular line of products is under the Lipo-6 series, including Lipo-6 Black Training.

Marketing Claims Made

The following claims were made about Lipo-6 Black Training:

  • Super potent stimulation: Well, you’ll definitely be fully stimulated. 400+ mg of caffeine isn’t to be taken lightly. Combine that with rauwolscine, another potent stimulant, and you’re going to have to lift the equivalent of an elephant to rid yourself of the energy surge.
  • Mental Focus: There’s choline but in bitartrate form. It does have a full gram dosage, so maybe it will work on your brain somehow.
  • Best pumps you will ever have: Um, no. Glycerol is a pump boosting ingredient, but it’s not its real purpose in a pre-workout. Citrulline malate is a much superior ingredient. At most, glycerol should help muscle hydration but that’s it.

What’s in it?

Now, let’s take a closer look at what’s inside the Lipo-6 Black Training:

  • Choline Bitartrate: Choline is the brain’s own version of “money.” Every little process, every signal sent is done with the help of choline [2]. The angle most supplements use with choline is the added brain focus and at one gram, you’re sure to feel a good surge. The form could have been better, but the dosage sort of makes up for it.
  • GlycerSize (65% Glycerol Powder): Glycerol is often included to help with muscle hydration, endurance, and a bit of muscle pump [3]. We only wish we had more than one gram.
  • Caffeine Anhydrous: The 375 mg dosage will definitely pack a punch [4]. While caffeine is really good for stimulation, that dose is almost FOUR cups of coffee.
  • Theobromine: This is an antioxidant and there seems to be some nootropic benefit to it [5]. Perhaps it’s to help counter the effects of caffeine, but we think l-theanine would have been a better fit. Not to mention the dosage is not even half what caffeine has.
  • Di-Caffeine Malate: This form of caffeine is supposed to help prevent the stomach issues (such as acidity) when ingesting high amounts of caffeine [6]. So, we have this at 50 mg and 375 mg of caffeine anhydrous. Yeah, this ain’t changing nothing. In fact, it might just make things worse.
  • Rauwolfia vomitoria extract std. 90% Rauwolscine: This is Yohimbine’s cousin [7]. What it does is a lot like yohimbine, but doesn’t have yohimbine’s common side effects on blood pressure and heart rate.
  • Black pepper as BioPerine: Normally, we’d praise the addition of BioPerine because it’s the best ingredient for boosting absorption of every ingredient in any formula [8]. However, the 1.25 mg disappointed us. The minimal dose is set at 5 mg, but Lipo-6 Black Training just had to cheap out on this.
  • Huperzine A: The 200 mcg may seem too tiny, but that’s the usual working range for Huperzine A, a nootropic that helps with memory and basic brain health [9].

The glaring benefit is the tidal wave of energy you’ll feel immediately upon ingestion. And from the amount of it, you’ll definitely want to find a way to get rid of the caffeine by roughing it out on the gym.

The other supporting benefit is for the brain when it comes to focus and attention.

The one thing we can’t see working for is a benefit for a pump. Glycerol alone isn’t enough especially because of that weak dose.


The obvious precaution would be on the stimulant overload. The total amount of caffeine is at 425 mg plus rauwolfia which is another stimulant. You’ll feel like you’re in “the zone” for sure, but after an hour or so you might end up crashing or worse, having a bad headache rendering you too much in pain to train.

We always recommend you speak with your doctor before taking any supplements featured on this site.

How to Take It

Nutrex recommends a pretty generic serving suggestion. They just want you to mix 1 scoop into 8-10 oz of cold water and consume 30-45 minutes before working out. They also insist on using only one serving in a 24-hour period and even warned about taking more than one scoop.

Given the amount of stimulation you’ll get, you’d have to be crazy to take more than one.


Currently, Lipo-6 Black Training has three flavors:

  • Orange
  • Wild Grape
  • Tropical Punch

Number of Servings

One container has 30 servings. This should translate to 30 days or more if you’re lowering the serving size intentionally due to the stimulants.

Lipo-6 Black Training vs American Metabolix Havok 

The best contender for Lipo-6 Black Training is American Metabolix Havok in terms of formula similarities.

Specifically, the energy and focus blend.

Below are the full dosages of the ingredients of American Metabolix Havok that Lipo-6 Black Training also has:

  • Caffeine, 250 mg
  • Choline bitartrate, 200 mg
  • Dicaffeine Malate, 75 mg
  • Rauwolscine, 1 mg

While it’s obvious that Lipo-6 Black Training has the advantage when it comes to dosing for all four ingredients, we think it’s not always about dosage but more of balance and synergy.

On top of the four ingredients, Havok’s energy and focus blend also contains a sizeable dosage of N-Acetyl-L-Tyrosine and other small-dosed stimulants. This makes Havok’s blend more efficient and not prone to causing side effects.

And to a deeper extent, this comparison exposes the stim-driven flaw of Lipo-6 Black Training’s formula. Because if you’re just going to create a formula that is dominated by stimulants, why don’t consumers just make their own? Caffeine’s cheap and surely you can buy choline bitartrate in bulk given it’s also the cheapest form of choline.

Customer Feedback

There weren’t any reviews on the actual website, and we also failed to find reviews in other places. This may be due to how it’s still new and recently launched this September.

Bottom Line

Based on our analysis, Lipo-6 Black Training is what you would call a really complicated stimulant bottle. The added focus, pump, and antioxidant pale in comparison to how the brand is just one big caffeine powder.

It works on energy and will surely deliver on performance, but so can 400 mg of generic caffeine off of Amazon.

The angle on focus is there, but the ingredients used (as well as dosages) were too small to dent the overwhelmingly stimulating formula Lipo-6 Black Training did.

There’s also no real pump here, folks. One gram of glycerol isn’t enough to make you feel like you have to lift something heavy. Even Citrulline Malate, considered the best ingredient for pumps, requires upwards of two grams to be considered useful.

The stim-driven approach also puts users at heavy risks of side effects which is actually offputting considering you take supplements to have a good time, not feel like the world is crushing your head.

Overall, we feel like Lipo-6 Black Training went extreme for extreme’s sake. There’s no substance, no synergy, just stimulation and we think this kind of formulation shouldn’t be sold at the price they marked on their website.
