Black Market Labs Pre-Workout Review - LeanBulking

About The Product

Tone: Pre-Workout is a supplement made by Black Market Labs. It costs $59.99 for 30 serving containers on their website, and comes in 3 flavors - Raspberry Lemonade, Orange Mango, and Stawberry Kiwi.

Sounds tasty, what ingredients are inside? More on that later.

Who are Black Market Labs? 

Black Market Labs consider themselves as a premium supplements company, based in Utah (USA). They specialize in pre-workout supplements, so were expecting big things from Tone: Pre-Workout.

Lets see whether its ingredients can prove its worth trying out.

Tone: Pre-Workout Ingredients Explained

As youve probably guessed from the name of this pre-workout, its designed to promote fat loss while still aimed to improve your workout. But were not sure why Black Market Labs have done this.

Basically, the best products are specialized in doing 1 thing really well - not trying to do 2 different things at once. For example, if we wanted to lose fat, wed buy a fat burner supplement. But pre-workouts should be designed to simply give you a kick in the gym.

Anyway, Tone: Pre-Workout does contain some key pre-workout ingredients; so well take you through its main ingredients - to show you how good it really is.

Black Market Labs Tone Pre-Workout Ingredient List Review

Heres Everything You Need To Know:


We always have mixed opinions about Beta-Alanine - its shown to enhance muscular endurance, but causes paresthesia (see side effects section for more info).

We prefer Creatine Monohydrate, which offers the same benefit (improved endurance) - without causing any side effects.

Smart-Caffeine Combo

When Caffeine & L-Theanine are consumed together, they form a smart-caffeine; this enhances the benefits of Caffeine in smaller dosages, while keeping you safe from side effects.

Black Market Labs has done well by adding this into Tone: Pre-Workout. But were annoyed that its part of a proprietary blend (meaning no-one knows the exact dosage of these ingredients inside).

This is bad, as dosages over 200mg Caffeine can cause side effects such as jitters and energy crashes. For this reason, we dont like proprietary blends and prefer to know exactly what were putting in our bodies.


L-Carnitine is one of our favorite ingredients inside pre-workouts; its proven to reduce fatigue and improve your focus in the gym.

However, as its inside a proprietary blend, there might not be enough for it to work (you need at least 500mg for L-Carnitine to work).

Citrulline Malate & Beetroot Extract

When it comes to experiencing skin-splitting muscle pumps, these 2 ingredients are your best tickets to get there. Basically, Citrulline Malate & Beetroot Extract are proven to increase nitric oxide levels - which results in more blood rushing to your muscles while you pump iron.

However, theyre part of proprietary blends - meaning they might not be dosed optimally and therefore wont work (you need at least 6,000mg of Citrulline Malate and 300mg of Beetroot Extract for them to work).

Fat Burning Ingredients 

As weve mentioned, Black Market Labs have tried to make this pre-workout into a pre-workout/fat burner hybrid. However, we believe that the best supplements offer one benefit extremely well (its harder to make a supplement deliver both benefits).

Simply put, fat burners work best when consumed 3-4 times per day. Tone: Pre-Workout is only designed to be consumed once per day, so the ingredients (such as Green Tea Extract and Green Coffee Bean Extract) wont be very effective.

But dont get us wrong, both Green Tea and Green Coffee Bean Extracts are key fat burning ingredients when dosed optimally and 3-4 times daily. Its just a shame that Black Market Labs didnt create a specialized fat burner supplement containing these 2 ingredients instead of adding them into Tone: Pre-Workout.

Side Effects

There are 2 things in Tone: Pre-Workout that can cause side effects - Bitter Orange Extract (Synephrine) and the unknown dosage of Caffeine.

Basically, Bitter Orange Extract has been banned in numerous countries (such as UK and Canada) for causing harmful side effects - which is why we avoid supplements containing it.

Not only that, Caffeine is very safe and effective when dosed under 200mg per serving. However, as its in a proprietary blend there might be a huge dosage in Tone: Pre-Workout without you knowing; which would cause jitters and energy crashes.

Heres the potential side effects from taking Tone: Pre-Workout: 

  • Nausea (Bitter Orange Peel)
  • Headache (Bitter Orange Peel)
  • Anxiety (Bitter Orange Peel)
  • Jitters (Caffeine dosage over 200mg per serving)
  • Energy Crashes (Caffeine dosage over 200mg per serving)

Tone: Pre-Workout Review Conclusion

We probably sound like we hate this pre-workout in this review - but we havent given it 3.5 stars for no reason (this is very high for our standards).

Tone: Pre-Workout contains many of our favorite ingredients. However, Black Market Labs has made a mistake by hiding them inside proprietary blends - meaning no-one knows the exact dosage of ingredients inside this product.

If it didnt contain any proprietary blends and didnt have Bitter Orange Peel inside, then it might have even appeared in our Top 3 Pre-Workout Supplements Page. But its these little mistakes which can bring a product down the list.

Fierce Tone: Pre-Workout Review

Bottom Line

Fierce Tone: Pre-Workout is better than many pre-workouts weve reviewed, but it cant compete with the very best on the market.
