Insane Labz (Dark Metal) Manson: An Evidence-Based Review

Manson is a pre-workout by Insane Labz under the Dark Metal brand.  Insane Labz is the same brand behind I Am God, another pre-workout with a pretty similar profile, but Manson promises to take the energy and aggression to another level.  The name appears to be derived from the infamous serious killer, Charles Manson.

Manson Claims

Like all the other pre-workouts released by Insane Labz, Dark Metal Manson is designed for energy and focus above all else, but does contain a few other ingredients which may be beneficial in other respects.

According to the packaging, Manson will provide:

  • Energy
  • Focus
  • Aggression (Is That Good?)

…Basically, Dark Metal is promising the same benefits with Manson that Insane Labz promises for all it’s pre-workouts, but the wording is a little more…unique with this one.  Here’s what Dark Metal/Insane Labz has to say about Manson:

Dark Metal Manson Description

But, as with any brands product pages, you shouldn’t buy into all the marketing hype.  How effective Manson is as a pre-workout simply depends on the ingredients, the doses of those ingredients, and your personal preference with regards to mental stimulation.

So let’s take a look at the ingredients…

Manson Ingredients

Although Manson appears mostly concerned with energy, the formula actually contains several non-stimulant ingredients as well.  Some you may recognize because they’ve been used in so many other pre-workouts, while some may be unfamiliar…

Beta-Alanine

Beta-Alanine is the rate-limiting amino acid in the synthesis of Carnosine, a dipeptide which accumulates in muscle tissue and increases muscular endurance.  Carnosine accomplishes this by “buffering”–or reducing the build-up of–Lactic Acid in the working muscle tissue.

Although Carnosine is comprised of Beta-Alanine and Histidine, studies have shown that Beta-Alanine is the only one neeeded to acheive meaningful increases in muscle Carnosine concentration.

In several studies, Beta-Alanine supplementation has been shown to increase Carnosine concentrations in muscle tissue and increase muscular endurance.  This has been noted in just about everyone, from athletes to novice lifters.

L-Tyrosine

L-Tyrosine is an amino acid which serves as the precursor to the neurotransmitters/hormones, Dopamine and Noradrenaline, both of which are capable of increasing mental alertness, energy, and focus.

Tyrosine supplementation has never been shown to increase levels of these neurotransmitters, indicating that the body has limiting factors at work which prevent all ingested Tyrosine from simply being converted into these neurotransmitters.

However, Tyrosine supplementation is an adequate means of supplying the brain with the substrate it needs to produce Dopamine and Noradrenaline.  In other words, Tyrosine is useful in instances of Dopamine and Noradrenaline depletion because it serves as a substrate to produce more.

Such instances may include:

  • Cold Exposure
  • Physical Stressors (such as exercise)
  • Metal Stress

And basically any other mentally depleting activity.  In the context of Manson, Tyrosine may be useful because ingredients such as Caffeine and Rauwolscine may cause the brain to secrete excess Dopamine and Noradrenaline which can then become depleted.  Tyrosine helps replenish these neurotransmitters and may reduce mental fatigue.

Manson contains an undisclosed amount of Tyrosine.

L-Taurine

Taurine is a unique amino acid which possesses anti-oxidant properties.  These properties give it a wide variety of potential health applications, the most reliable of which is probably exercise recovery.

Taurine has been shown, in multiple studies, to reduce oxidative damage from exercise, therebyenhancing exercise recovery.

In the area of exercise performance enhancement, Taurine has proven unreliable.  It has been shown to subtly improve exercise performance in one study, but has failed to do so elsewhere.

Manson contains an undisclosed amount of Taurine.

Caffeine Anhydrous/DiCaffeine Malate

Manson contains two types of Caffeine:

  • Caffeine Anhydrous – ordinary synthetic Caffeine
  • DiCaffeine Malate – Caffeine bonded with Malic Acid (2:1 ratio)

Although there may be some differences in the absorption of these two compounds, they basically serve the same function…supplying Caffeine.

Caffeine consumption triggers the release of neurotransmitters like Noradrenaline and Dopamine which enhance mental energy and focus, leading to better, longer workouts.

In the context of Manson, Caffeine is probably the most important ingredient.  It’s not the only stimulant, but it’s definitely the primary one.  Unfortunately, Insane Lab/Dark Metal Inc gives us no indication of how much Caffeine is present in Manson.

All we have to go by is a 5g proprietary blend of which Caffeine is the 4/5th most abundant ingredient.

L-Carnitine L-Tartrate

L-Carnitine L-Tartrate (LCLT) is a fast-absorbing form of Carnitine, an amino acid which possesses anti-oxidant properties.  Like Taurine, LCLT has been shown to enhance aspects of exercise recovery by reducing oxidative damage to muscle tissue during exercise.

Unlike Taurine, however, L-Carnitine L-Tartrate may also enhance performance, having been shown to do so in atleast one study.  An increase in muscle oxygenation is thought to be the reason for this. although further study is required to carve out a precise mechanism of action.

The clinical range for LCLT is 1-2g, but unfortunately, we have no idea how much Manson contains.  Could be 1g.  Could be close to nothing.  We sure wish Insane Labz would ditch the proprietary blends and just tell us!

AMPiberry (Juniperus Communis)

AMPiberry is Insane Labz’s special name for Juniperus Communis which allegedly contains AMP Citrate (DMBA) naturally.  Insane Labz doesn’t outright say this, but it’s implied by the name.

It’s been about two years since Genomyx, another Lecheek-related brand, was issued a letter from the FDA stating that AMP Citrate is an illegal adulterant.  Genomyx promised to cease producing products with AMP Citrate, but if we had to guess, AMPiberry is actually just synthetic AMP Citrate.

As we discussed in our Orchilean article, it’s realy easy for any manufacturer to simply sprinkle some synthetic chemical like AMP Citrate into a proprietary blend and then claim that the stimulant-power is derived from an herbal source.  In this case, Juniperus Communis.

While we doubt that Insane Labz has found a form of Juniperus Communis that actually contains AMP Citrate, this is good news if you like stimulants.  Still, it’s not officially confirmed that Manson contains AMP Citrate…Just a guess based on a whole lot of research which we do here at SuppWithThat.com.

OXYGOLD (Fulvic Acid)

Fulvic Acid is kind of a “buzz ingredient” these days.  It’s not entirely clear what the point of including it in a pre-workout would be and Insane Labz certainly makes no effort to explain it, but we assume it just has to do with the general health benefits that are commonly associated with Fulvic Acid supplementation.

Whether or not these really matter while your working out is up for debate.  As with every other ingredient in Manson, we have no idea how much Fulvic Acid there is in the formula.

Rauwolfia Vomitoria Extract

Rauwolfia Vomitoria is typically supposed to be standardized for Rauwolscine (Alpha-Yohimbine) content.  Dark Metal Inc/Insane Labz lists the standardization at 90% but it’s not clear how much of the extract there is in the first place.

Given that Rauwolscine tends to provide a powerful stimulant experience at low doses (1-3mg), we doubt Manson contains much more than that.  Anywhere from .5-2mg would be our guess, but that definitely qualifies as an effective dose.

Our only issue here is that the Rauwolscine comes from an extract and isn’t synthetic (like Rauwolscine HCL).  Extracts tend to be unpredictible in terms of chemical components and Rauwolfia Vomitoria is no exception.  There are probably a bunch of other Yohimbine-like chemical-relatives at work here as well, not just Rauwolscine.

Just another reason to be careful with the dosing (start low!).

Manson Ingredient Takeaway

The ingredient profile of Dark Metal Manson is fairly straight-forward, except for ingredients like AMPiberry and Fulvic Acid.  Other than those, everything makes sense and everything has a purpose.  We’re not saying AMPiberry and Fulvic Acid are useless, we’re just saying they haven’t been studied well in terms of exercise performance enhancement.

So what are they doing in a pre-workout supplement?  We have no idea…

By and large, you can expect a fair bit of stimulation from Manson, even if it’s just from Caffeine and Rauwolscine.  These two ingredients alone typically produce a stream of steady energy, focus, and more fat-burning, but the other ingredients may help as well.

Why Is Insane Labz Sticking With Proprietary Blends?

We don’t know…

One of the most frustrating aspects about Insane Labz products is that they tend to use proprietary blends (as is the case with Manson) instead of listing the dose of each ingredient.  This makes it pretty much impossible to determine before-hand how much Manson will increase your focus, energy, muscular endurance, and fat-burning.

All we can do is speculate based on a 5g, 9 ingredient proprietary blend.  Needless to say, this is pretty difficult to do.  So, we’ll leave it at this…

Start with the lowest dose, determine how much it does, then go from there.

Is Manson Safe?

None of the ingredients in Manson are considered especially dangerous, but because Insane Labz/Dark Metal doesn’t disclose the amount of each ingredient, caution should be exercised with first-time use.

We would absolutely NOT recommend exceeding the lowest possible dose your first time using this product.  You have no idea how much Caffeine (or other stimulants) you’re taking in and, to some, that may be a problem.

If you’re sensitive to stimulants, you should probably just stay away from Manson.

How To Use Manson For Best Results

Manson is a pre-workout supplement which is primarily geared toward increasing mental energy and  focus, so you’ll want to take it just before you workout.  Take 1 serving of Manson anywhere from 5-30 minutes before your workout.  Most people will feel the stimulating effects within a few minutes or so.

The impact of ingredients like Beta-Alanine takes atleast a few weeks to become noticeable.

Where To Buy

Dark Metal Manson is available at:

And possibly some more retailers in the future.  If you know of any other retailers that carry Dark Metal Manson, let us know in the comments below!

The Bottom Line

If you’re looking for a heavy-stim pre-workout that hits hard in terms of energy and focus, and don’t mind not knowing exactly what you’re consuming or how much of it you’re consuming, Manson is a fine choice.

It won’t make our Best Pre-Workouts For Stimulant Lovers list because it isn’t transparently labeled, but most people will probably feel pretty stimmed-out when taking Manson.

It’s very similar to other Lecheek/Insane Labs/Dark Metal products, so if you’re tried those and liked them, you’ll probably like Manson as well.
