It’s a well established brand, and is sold mainly from respected retailers like

They produce a range of products that cover various aspects of the lifting lifestyle.

The Ingredients and how they work

For MusclePharm’s Assault, all you need is one scoop around 20 – 30 minutes before training.

That’s it.

The caffeine dosage is high in this product. Do not be tempted to double scoop it – the results could be dangerous.

As for the individual ingredients, this is what you need to know.


One of the better choices for power output.

Supplementing creatine increases overall water retention which allows you to have more explosive power.

It’s ideal for boosting strength.

CaroSyn Beta-Alanine

Beta-Alanine has mixed feedback.

Although effective for buffering the acid in your muscles – which helps you manage with prolonged bouts of high intensity – Beta Alanine also causes a distracting side effect.

In large doses it has been linked to paresthesia – which we’ll cover in more detail in the side effects section below.

Betaine Anhydrous

A component of beet root that may help with overall training volume.

However, it is not as effective as pure beet root.

Originally thought to work as a stimulant – considering its used so widely in energy drinks.

However, studies have shown that this is not the case. Taurine helps with blood flow, and may help with muscle pumps to a minor extent.


An amino acid that has been linked to sleep quality.

It does not promote muscle pumps, energy, focus or strength.

It may help with the jitters from caffeine, but studies are limited.

Caffeine Anhydrous

One of the better ingredients for energy. Caffeine has been seen to increase power output, metabolism and energy levels.

It’s a reliable stimulant and there are more than enough studies to back up its effectiveness.

Acetyl-L Carnitine

An amino acid with some good supportive effects.

Helping energy and metabolism L-Carnitine could help fuel your workout.

However in this case there is only 250mg in MusclePharm Assault.

Studies have shown you need at least 500mg to see any effective results. It’s not your best option.

Ingredients Recap

On the whole, this is a good nutrient profile.

There’s enough to boost your strength and energy levels here to definitely see some results.

However, we recommend you start on a lower dose – as it contains 250mg of caffeine per serving.

This is around 3 strong cups of coffee.

Start on a half dose, assess your tolerance, and work your way up.

Side Effects

There are two things in this product that may give you side effects – the Beta Alanine and caffeine.

Beta Alanine has been know to cause paresthesia – a short term tingling and itching.

It’s not harmful, but it is very distracting and frustrating while you’re training.

The caffeine is pretty high too. At 250mg in one serving, your best bet is too start with a smaller scoop. Side effects from too much caffeine include:

  • Jitters
  • Headaches
  • Heart Palpitations
  • Nausea
  • Raised Blood Pressure

Which is not the kind of scare you need while training.

MusclePharm Assault Review Conclusion

On the whole, this is a reliable pre workout.

It contains a good range of ingredients and can deliver what you need for an effective gym session.

However it’s definitely not the best we’ve seen.

The caffeine dosage is a little higher, but you should be able to handle it – once your tolerance has built up.

We definitely don’t recommend double scooping.

You also may get itchy hands and face from paresthesia – and that will be distracting.

All in all though, you should some effective results.
