About the Company

Controlled Labs is a supplements company that markets a range of products, from fat burners to pre-workout supplements.

They’re based in the US, but there’s not much information about them on their website available.

The Ingredients and How They Work

Straight away from looking at Purple Wraath’s ingredient list, we see some negatives. All of the ingredients are part of two proprietary blends, meaning the overall quantites are shown to you (7,000mg & 2,700mg), but you’ll never know the exact doses of each individual ingredient.

This is a problem, as you might be sensitive to a certain ingredient, so you’ll be more at risk from suffering from side effects. However, there are some positives – Purple Wraath contains some great ingredients like Citrulline Malate.

See for yourself:

Branched Chain Amino Acids (L-Leucine & L-Isoleucine) 

These are two of the three BCAAs – the one that’s missing is L-Valine. But L-Leucine is the most beneficial BCAA, promoting muscle synthesis and recovery.

However, all three Branched Chain Amino Acids can be consumed through a well-planned diet, as they’re found in high protein foods. Ultimately, BCAAs aren’t vital to a pre-workout.


This is another amino acid that’s most commonly used to reduce herpes simplex symptoms and treat Parkinson’s disease. However, no studies have found any benefit that aids your gym session.


In theory, L-Arginine should be a great at delivering great muscle pumps, as L-Arginine is responsible for boosting nitric oxide levels in your body.

However, when orally supplemented, L-Arginine has a poor absorption rate – meaning it has very minimal or no effect.

If you’re looking for intense muscle pumps, then Citrulline Malate or L-Citrulline is the best ingredient, as it turns into L-Arginine in your kidneys and has a great absorption rate – this makes it very reliable.


This is an amino acid that adults product enough naturally. It’s been added into Purple Wraath as it’s believed to promote muscle gains.

However, there’s been no human studies to prove that L-Histidine delivers this benefit – this also means that it’s unknown whether it comes with risks of side effects.

A pre-workout supplement isn’t designed to significantly increase muscle gains, leave that to the products specifically marketed for that. You want a pre-workout supplement that boosts your

We recommend staying away from this ingredient until it’s proven safe and effective.


L-Threonine is an amino acid that’s the building blocks of protein in your body. It’s used as sleep and depression aid due to it’s ability to calm your nervous system.

However, there hasn’t been any studies conducted to prove that L-Threonine benefits your gym session. For this reason, it’s likely to be an ineffective ingredient in a Purple Wraath.

L-Methnionine & L-Phenylalanine

We’ve grouped these two ingredients together as they’re both amino acids. None of either ingredients’ benefits will enhance your training session in the gym.


This is a molecule that’s shown to improve muscular endurance, but can cause paresthesia.

Paresthesia is a tingling on the skin of your face, chest, hands, and extremities in doses over 0.8-1g – it’s not life threatening, but it’s uncomfortable enough to ruin your workout.

As Beta-Alanine is part of a proprietary blend, you’ll never know how much is contained in Purple Wraath – meaning you could be at risk from experiencing paresthesia.

We recommend staying away from this ingredient, as there are other ingredients that offer the same benefit without risks of side effect, such as Creatine Monohydrate.

Citrulline Malate

This is one the best ingredient in Purple Wraath. It turns into L-Arginine in your kidneys after oral supplementation, which raises nitric oxide levels.

Ultimately, this results in intense muscle pumps while you lift weights in the gym. But you might be thinking, why not take L-Arginine directly?

Well, L-Arginine has a poor absorption rate, meaning your body can’t process it to benefit you. On the other hand, Citrulline has a great absorption rate, so it’s reliable in delivering great muscle pumps.

Citrulline Malate’s a key ingredient for a pre-workout, so we recommend making sure it’s on the ingredient list – but it’s important to know that it’s optimal dose is 6,000mg-8,000mg.

This is a problem. As this ingredient’s part of a proprietary blend, you don’t know the exact amount in Purple Wraath. There might be a minimal amount of Citrulline Malate contained, which would make it ineffective.

Betaine Anhydrous

Also known as Trimethylglycine, it’s found in Beetroot and believed to enhance endurance in the gym. However, studies have shown that it doesn’t provide this benefit.

What’s even worse, is that it comes with a side effect. Betaine’s known to cause fishy odors in the breath and body secretions – something you don’t really want.

For an ineffective ingredient, it’s not worth suffering from this side effect. We recommend staying away from Betaine.


Everyone knows what Ginger is, as it’s used in food and traditionally in Chinese and Indian (Ayurveda) medicine –  1-3g doses have shown to reduce nausea.

However, apart from aiding digestion, it doesn’t offer anymore benefits to boost your gym session. It’s not vital to a pre-workout, but there’s not any negatives to Ginger either (as long as you’re not allergic to it).


This has been added into Purple Wraath as it’s believed to improve muscle pumps by 60%. It works by reducing the amount of Arginese (the enzyme that inhibits nitric oxide), therefore raising your nitric oxide levels.

However, no studies have proven this ingredient to be effective, and it comes with numerous side effects – such as nausea, fatigue, and feeling lightheaded.

The only key ingredient in Purple Wraath is Citrulline Malate. The rest of it’s nutrient profile is made up of ineffective or unproven nutrients.

  • Fishy odors from breath and body secretions (Betaine)
  • Nausea (L-Norvaline)

Pro’s and Con’s


  • Citrulline Malate is a key ingredient in any pre-workout supplement.


  • Contains 2 proprietary blends – meaning you don’t know exact doses of individual ingredients.
  • Numerous potential side effects.
  • Some ineffective ingredients included (eg. Betaine).
  • Missing key ingredients for a pre-workout, with muscle building ingredients added instead.

Purple Wraath Review Conclusion

It’s never great to see all the ingredients in a product inside proprietary blends – you’ll never know the exact doses of each ingredient, which could lead to numerous problems, especially if you’re sensitive to any.

But it gets worse for Purple Wraath. The only effective ingredient in this pre-workout is Citrulline Malate, and even this might be ineffective if it’s dosed lower than 6,000-8,000mg (its optimal dose).

We recommend looking for a pre-workout supplement that doesn’t contain any proprietary blends – so you know exactly what you’re getting and how beneficial it is.
