Musclepharm Assault pre workouts

Musclepharm Pre Workouts Reviewed

Here we’ve reviewed and compared Musclepharm’s Assault, Assault Black, Wreckage, Combat, and Natural Pre Workout.

Ever since MMA took off, the sponsoring brand Musclepharm has been a big name in sports nutrition stores (1).

The pre workout Assault is easily one of their most popular products, with applications across multiple workouts and sports.

It really is quite impressive that Assault has survived so long, considering back in 2012 it had to compete with pre workouts containing DMAA like jack3d once did in a quite dirty environment (2).

Though it lived on, putting safety concerns to rest while many other supplements dropped out (3).

Flash forward to today, and we have:

  • A new Assault formulation
  • Assault Black
  • Wreckage
  • Musclepharm Combat
  • Musclepharm Natural Pre

The times have certainly changed.

So how do these products compare to the old version you loved? Here we explain:

Musclepharm Assault and its new formula:

Assault reviewFor starters it is absolutely essential to point out that the Assault we have today is nothing like its former formula.

Musclepharm basically took a ripsaw to the old Assault, taking a once ingredient-rich formula and making it into a small-dose shelf stuffer.

Take a look here for a direct label comparison of the new Assault vs old Assault pre workout:

Old vs New MP Assault

As you can see, quite a few ingredient cuts have been made:

  • The old assault had a 23 gram serving size containing 28 different active ingredients
  • The new Assault formula has an 11.5 gram serving size and only 11 active ingredients

We’re not a big fan of this reformulation at all, and apparently neither are collegiate athletes who attempted to improve performance with Assault to little avail (4).

In comparison, the old Assault formula showed promise for delaying fatigue (5) and improving performance (6), well, most of the time (7).

Primary ingredients in Assault pre workout:

  • Creatine monohydrate 3 grams
  • Beta-alanine 1.75 grams
  • Betaine anhydrous 1.5 grams
  • Taurine 1 gram
  • L-glycine 1 gram
  • Caffeine anhydrous 250 mg
  • Acetyl l-carnosine 250 mg

Basically, it looks like Musclepharm decided that they wanted their pre workout to be more like Cellucor C4.

So, how does Assault Black Label compare to this?

Musclepharm Assault Black

Assault Black ReviewAssault Black looks super chic and hardcore with its bold new design, so what exactly has changed compared to Musclepharm’s standard Assault pre workout?


  • The standard Assault formula is: 11.5 grams
  • While Assault Black’s formula is: 11.6 grams

What, what?

You read it right, while Assault Black costs about 34% more per serving, you’re only getting 0.1 grams more!

Perhaps the ingredients chosen save it, let’s take a look at a direct comparison between Assault and Assault Black:

New Assault vs Black

As you can see, while the serving size of each product are near-similar, the ingredient choices differ substantially.

Unique ingredients in Assault Black:

  • L-citrulline dl-malate 3 grams [under-dosed]
  • Agmatine sulfate 750 mg [dosed well]
  • Beet root 200 mg [under-dosed]
  • Hawthorn Berry 200 mg [dosed well]
  • Creatine HCl 1.5 grams [dosed well]
  • BCAAs 1.5 grams [under-dosed]
  • ElevATP 100 mg [dosed well]
  • Caffeine 300 mg [strong]
  • Huperzine A 100 mcg [dosed well]

If you are ingredient savvy, you’ve likely noticed that while the ingredient selection is good, the dosing is quite bad for: l-citrulline dl malate, beta-alanine, beet root, and branch chain amino acids.

Fortunately for Musclepharm, the new Assault Black formula appears to work, having increased performance via power output and energy in collage males (8).

How Assault and Assault Black Compare in the Gym

In the gym, both of these pre workouts will give you substantial energy to workout as long as you’re not accustomed to crazy high stimulant pre workouts.

Assault is really a creatine based pre workout, and you will notice a progressive increase in strength while you take it if you haven’t been taking creatine supplements already.

Assault Black on the other hand will offer creatine power thanks to its creatine HCL, but it will also have more energy from 50 mg more caffeine, plus some pump from the 3 g citrulline malate and 750 mg Agmatine sulfate.

Well, assuming the caffeine dosage and ingredient label are accurate which isn’t’ always the case (9).

Making a direct comparison between the two, we believe that they both fulfill the same purpose as energy and creatine providing pre workout supplements. One isn’t 100% distinctly better than the other.

Other Musclepharm pre workout supplements

We won’t go into extensive detail, but Musclepharm also makes the following pre workouts:

Combat pre workout

Musclepharm Combat ReviewMusclepharm’s Combat pre workout is essentially Assaults minimal ingredient mantra fused with Assault Black’s love for l-citrulline.

Viola, we have: Combat.
The most interesting thing about Combat pre workout, is that it contains l-theanine in the formula. L-theanine helps to well-round the caffeine experience, leading to a more blissful lift.

Compared to Assault, we would have to say that Combat takes the gold medal in trying to re-enact C4 by Cellucor.


Musclepharm WreckageMusclepharm’s Wreckage goes beyond the standard Assault and Assault black formulas. Think of it is Assault Black, Deluxe.

Teaser: Wreckage packs more ingredients than both Assault versions.

Musclepharm Natural Pre-Workout

Musclepharm NaturalIf you think less is more, then Musclepharm’s natural pre workout may be just the empty thing for you.

Say hello to:

  • 1.5 grams betaine
  • 1 gram l-citrulline
  • 500 mg vitacherry
  • and a natural stimulant matrix totaling under 400 mg.

All for a whopping serving size of 11.6 grams (don’t mind the 6 grams of carbs).

What’s really interesting about this pre workout, is the stimulant matrix name: G-4. Does this remind you of any popular product, made by say, Cellucor?


Needless to say, we’re not fans.

Conclusion on MP’s line of pre workout supplements

Overall, these are great entry level pre workouts. They aren’t ‘extra special’ by any means. But for the masses, this is all someone really wants or needs – so we won’t bash it too much with our crazy high standards.

Overall we were pleased with both assault pre workouts, even though they are not as good as the original formulas. Currently, Assault Black is ranked on our best reviewed pre workout supplements.

PS: Comment below what you thought if you’ve taken any of these assault formulas. Likewise, let us know if you felt any stomach discomfort or nausea from them. This is something we are exploring.
