MyProtein Pre-Workout Blend Review



This is our MyProtein Pre-Workout Blend Review.

MyProtein was the very first supplement company I purchased from when I began getting into fitness.

The first product I ever purchased was their whey protein powder, and for some unknown reason, I decided to buy the unflavored version. Probably because it was cheaper.

Since then, I’ve tried numerous MyProtein products, and today we’re going to be looking at their Pre-Workout Blend.


MyProtein Pre-Workout Blend Review


Before we get started, I should mention that this isn’t my favorite pre-workout product from MyProtein. A couple of years ago I tried their Phasetech Pre Workout+ in the Sour Gummy flavor, and it was amazing.

Unfortunately, it’s currently out of stock, and it looks like they’re tweaking some things.

In this review of MyProtein’s Pre-Workout Blend, we’re covering the following:

  • Bag size/servings
  • Scoop size
  • Suggested stacks
  • Ingredients
  • Flavors
  • Pricing
  • Where to buy
  • Effectiveness
  • Summary


Important Information

Before we get into the big stuff like the ingredients, prices, flavors, and effectiveness; let’s quickly cover some important information on servings, product weight, and potential supplement stacks.


Bag Size/Servings

MyProtein offers two different bag sizes for their pre-workout blend. Either a 250g bag that contains 22 servings, or a 500g bag that contains 43 servings. Normally a pre-workout product will contain between 25 to 30 servings per container.

Scoop Size

A single scoop or serving of the Pre-Workout Blend weighs 11.5g. It’s not the densest pre-workout serving we’ve seen, but at least it’s not one of those 5g serving fluff products.

Suggested Stacks

MyProtein suggests stacking their Pre-Workout Blend with their Essential BCAA 2:1:1 product.


MyProtein Pre-Workout Blend Ingredients/Supplement Facts

MyProtein uses some solid ingredient choices in their Pre-Workout Blend, however, the dosages for some of them are not considered optimal. If it weren’t for a couple of issues, you could easily double up the dosages and have an awesome pre-workout product.

Here’s a full breakdown of MyProtein’s Pre-Workout Blend’s ingredients and dosages:


Citrulline Malate – 3000mg

Citrulline malate is a compound containing L-citrulline and malic acid at a 2:1 ratio. In other words, this formula contains 2000mg of L-citrulline and 1000mg of malic acid.

The ‘clinically effective dosage’ begins at 3500mg of L-citrulline, so this formula is fairly underdosed.


Beta-Alanine -​ 1600mg

Beta-alanine is the ingredient in pre-workout supplements that gives you that tingling, and somewhat itchy effect. It’s used to increase the concentration of carnosine levels in the muscle tissue.

The optimal dosage in pre-workout supplements is 3200mg, but to see the potential ‘benefits’ requires a loading phase of 179g in 28 days. Meaning you’d need to be taking 6g a day to see the desired effects, and no pre-workout will come close to that number.


L-Arginine AKG – 1500mg

L-arginine may improve circulation as a precursor to nitric oxide, which is a vasodilator that widens your blood vessels, allowing for increased blood flow.

When it comes to boosting nitric oxide, there are four main ingredients often used to achieve this:

  • L-citrulline
  • Agmatine
  • L-Arginine
  • Nitrates

L-arginine is widely considered the worst of the four, and many state that there are no additional benefits from taking more than one of the above side by side.

MyProtein would have been better off leaving this ingredient out and instead boosting their citrulline malate dosage.


L-Tyrosine – 1000mg

L-tyrosine is used as a cognitive enhancer and may help boost concentration and focus. It’s incredibly useful in pre-workout supplements as it may help balance out the caffeine, and reduce specific negative side effects of caffeine usage, such as jitters.

The minimal ‘clinically effective’ dosage is 1000mg, but it’s always nice to see this a little higher towards 1500mg.


Taurine – 1000mg

Taurine is a controversial ingredient for a pre-workout supplement. Whilst it may be beneficial in regulating many different bodily functions, it also has an anti-inflammatory effect. One of the main goals of a pre-workout is to increase nitric oxide levels and pump as much blood as possible to the muscle tissue.

This ingredient could potentially aid in the exact opposite.


Betaine – 1000mg

Betaine is used in pre-workouts for improving hydration levels in the muscle tissue, potentially leading to increased power output. Whilst the research is still quite limited, more and more companies are including betaine in their supplements.

The recommended dosage is normally between 2000mg and 2500mg, so this dosage of 1000mg is again on the low end.


Caffeine – 150mg

Caffeine will always be the driving force behind a stimulant-based pre-workout supplement. A dosage of 150mg puts this product at a relatively low-stim level. The caffeine dosages in pre-workouts can often range between 140mg to 400mg at the top end.


Guarana Seed Extract – 100mg

Guarana contains stimulants such as caffeine and theobromine, which are both highly important for a pre-workout supplement. It also contains several antioxidants.


Other Ingredients:

  • Vitamin C – 75mg
  • Niacin – 3mg 
  • Vitamin B2 – 1.4mg
  • Vitamin B6 – 1.4mg
  • Vitamin B1 – 1.1mg
  • Vitamin B12 – 1.5µg


Flavor Options

When you buy a MyProtein supplement, you’ll normally have a ridiculous number of options when it comes to flavor. However, this isn’t the case for their Pre-Workout Blend. They offer four flavors, with one of them being Cola, which is an interesting change of pace.

Still, four flavors are better than one, and in our opinion, the Orange Mango Passionfruit is the best one available.

Here’s a list of all the current flavor options for MyProtein’s Pre-Workout Blend:

  • Blue Raspberry
  • Cola
  • Fruit Punch
  • Orange Mango Passionfruit

Now we’ve covered all the important information about the product itself, let’s talk about the cost.

The price of the Pre-Workout Blend is £15.99 and is only available for European countries. For 22 servings, this is great value, however, because some of the dosages are slightly low, we’d recommend buying their citrulline malate powder separately, and adding an extra 3-6g of it into your pre-workout shaker.

Where can you buy MyProtein’s Pre-Workout Blend?

You can buy MyProtein’s Pre-Workout Blend on their official website, or on Amazon. 



It’s likely that anybody with experience in supplementation and fitness won’t feel much when taking this pre-workout. This is a beginner pre-workout, with low stim content, and several other very useful ingredients but with low dosages.

For someone like myself, when taking this product it didn’t really do too much for me. I like higher stim pre-workouts, with optimal dosages of every ingredient involved.



So where does MyProtein’s Pre-Workout Blend stack up as a pre-workout?

In our personal opinion, this is likely a pre-workout for beginners. For people who are new to pre-workouts and want to test their tolerances first. Whilst there are good dosages of taurine and l-tyrosine, the caffeine, citrulline malate and beta-alanine dosages are all very low.

It’s a cheap pre-workout, using well-studied ingredients and the flavors are great. However, you’re not going to be seeing the optimal physical performance increases from taking this pre-workout. This is not the only pre-workout supplement that MyProtein sells, and that’s why we’ve suggested it as an option for beginners only.
