Carnosyn logo

Beta-Alanine (Carnosyn): Beta-alanine helps to delay fatigue (buffer lactic acid in muscles) and increase physical performance. Beta-alanine can aid lean mass gain.*

Citrulline Malate:
Citrulline malate may help replenish energy and fuel ongoing muscular contractions for more intense training sessions.*

elevATP logo

Elevatp: elevATP is a clinically researched ingredient that works with our natural energy-producing mechanisms to stimulate production of ATP (the energy currency of the body).*

Creatine HCL: A form of creatine that dissolves easier than creatine monohydrate. This may lead to better absorption and lower dosages. Creatine is the most effective and researched supplement today which has been shown to increase strength, power, lean mass, and performance.*

BioPerine logo

Bioperine Black Pepper: BioPerine significantly enhances the bioavailability of various supplement nutrients through increased absorption.*

Agmatine Sulfate: Agmatine stimulates many processes that are essential during a hard training session for optimal vasodilation (pump) and energy.*

BCAAs (L-Leucine, L-Valine, L-Isoleucine): Branched chain amino acids (BCAAs) can promote muscle recovery (muscle protein synthesis) and increase muscle growth over time. It may also help to prevent fatigue in novice athletes.*

Caffeine Anhydrous: Caffeine anhydrous is a powerful stimulant, and it can be used to improve physical strength and endurance.*

Great choice for my go to pre workout! You can feel the pump 10minutes after consumption. Worth every penny!

This product is decent enough. The taste is good but I didn't feel huge pumps like I have with other products. Still, it gives you the energy you need for your workouts, especially if you workout in the morning.

Fruit punch is synonymous for being a generally intolerable and bland flavour. Not MP Assault Black though. The fruit punch flavour has got to be one of the best tasting currently out in the market. Extremely well rounded pre-workout powder excelling in all areas of pump, steady energy, muscle building and focus.

The Assault Black is better than regular Assault but neither compare to the original Assault. When MP changed the ingredients the results weren't as good! I'm looking forward to finishing this pre-workout and will give MP's Wreckage pre-workout a try, hoping that it will be like the original Assault that beat all brands!

Just bought a bottle of this, I'm giving the performance a 9 right now because i am trying some private company pre workout supplements. I will revisit this review shortly. But for now I am giving the flavor a 10/10 and performance a 9/10. Way better than C4 which i gave a 7/10. Pump is good and endurance is great. MOST important to me is that this does not make me feel insane after my workout where other brands do. Try this and use a full scoop you will like this.

I absolutely love this product! Far from "not having any kick", it actually has too much! I had to dial down my dose to a 1/2 - 3/4 scoop. A full scoop leaves me far too cracked out! On this stuff I have the most INSANE workouts! And afterward I'm still buzzing, so I'll go run for 6-9 miles! It's literally made me into a SUPERMAN! It tastes amazing, too, and mixes very easily, as well. I can't say enough good things about this product!

I was excited about getting the "black" edition because I thought it would have a little more kick but I was disappointed because it didn't have a kick at all...the regular assault has more. The flavor was good...

This product is alright. I've been using it for about 2 weeks now on an empty stomach in the A.M. and it doesn't seem like anything special. Ive used NO Explode, C4 Ripped. Mr. Hyde, Vapor X5, O.N. Gold Standard Pre-workout etc. and this seems to be the least effect of that list. Dont get me wrong it gives you a nice little energy buzz, but its more comparable to about a cup of coffee and the effects seem to diminish 15-20 min into a workout. If you're into more of a natural type of pre-workout that isn't over powering you'll like this but I prefer something stronger like Mr. Hyde.

This product is really expensive in comparison to other brands including its own brand of regular assault. And doesn't do much. Flavour is really good which is why I buy it. Since they reformulated the regular assault they got rid of all their good flavours and the product sucks to be honest. Stopped buying regular assault and stopped buying black assault.

I realy like it, great energy, pump and focus. taste is very good too. A good overall preworkout, i like to switch between this one and supernova. citruline + agmatine give a nice pump until the end of my workout. no jitter and it taste very good :)

Highly underrated pre workout. Equivalent ingredients compared to other top more expensive pre workouts (PreJym, Pre-Kaged). This is really a more sensible cost effective pre workout that really gives you a great feel. I've taken PreJym, Pre-Kaged, GAT PMP, GAT Nitraflex. I used to add in Creatine HCl to my GAT products to get a pump equivalent to this, but this already includes Creatine HCl. I highly recommend you give this a shot. The taste, is possibly one of the best pre workouts I've had. 10/10.

This product is not what I expected, for the price and only 30 servings I expected something better. I was not pleased with the product, there are many pre workout that are much better and cost much less.

Assault Black is definitely worth the buy. It has given the boost I was looking for without the jitters.
