I saw someone in my gym using MYPROTEIN The Pre-Workout a month ago, and I thought to myself - it’s time for a MYPROTEIN pre-workout review.

I have used MYPROTEIN’s whey isolate protein powder for years at this point, and I love it, so why not give their other products a chance.

So, for the past three weeks, I’ve been supplementing with MYPROTEIN pre-workout, and here’s how that went.

Pros

  • Great taste
  • Simple-enough formula
  • Beginner and expert-friendly
  • Can be safely double-scooped
  • Brilliant deal when on sale

Cons

  • Did cause beta-alanine tingles
  • A double dose is not cost-effective

MyProtein Pre-Workout Review

MYPROTEIN pre-workout is something I’d call a decent pre-workout formula. It is potent enough to make you feel it working, but if you want to achieve peak performance, you will have to double-scoop.

On the other hand, I managed to get my tub when it was on sale, so double-scooping was incredibly affordable and made the pre-workout extremely effective, both cost and performance-wise.

So, the gist of this mini MYPROTEIN pre-workout review is that if you can get it on sale, you’ll get yourself an outstanding product.

My Ratings Explained

A 4.2 out of 5 for ingredients is the best I can do for MYPROTEIN pre-workout. The ingredient choice is good, and I don’t mind any of them. However, if MYPROTEIN would ditch betaine and replace that with more citrulline and tyrosine, it would be perfect.

On the other hand, 4.3 out of 5 for effectiveness may be too high, but it’s the middle ground between single and double-scooping. In other words, a single scoop of MYPROTEIN pre-workout is fine, but the double-scoop is nearly perfect.

Finally, a 4.3 out of 5 for the price is once again the median grade between MSRP and the “On sale” price. One is just your standard $1.5 per serving, and the other makes the double dose cost $1.72, which is beyond incredible.

Will My Performance Increase?

If my experience during the MYPROTEIN pre-workout review is anything to go by - your performance will increase. I saw a decent difference in my mental and athletic performance when I took a single serving of MYPROTEIN pre-workout.

MyProtein Pre-Workout Performance Graph Single Serving

I felt more energy going into a workout, and while I didn’t necessarily feel stronger, I did manage to squeeze in a few extra reps here and there.

My pumps and endurance weren’t all that great, but I could definitely tell it was better than my baseline.

On the other hand, double-scooping MYPROTEIN pre-workout took me straight to my peak performance.

MyProtein Pre-Workout Performance Graph Double Serving

I was flying! I was stronger, I was completely focused, and my pumps were filling up my shirt to the brim.

Even the post-workout Stairmaster felt much easier than usual, allowing me to go really hard for 15 minutes straight.

How Will I Feel Post-Workout?

In all honesty, I’d say that most of the effects of MYPROTEIN pre-workout would dissipate post-workout. I couldn’t really tell the difference in my energy or focus, but I will say I didn’t feel as drained as I would if I hadn’t taken it.

More often than not, I wouldn’t need to lie down and relax after training, but I can’t sit here and lie to you I wouldn’t appreciate it.

On the other hand, if I took a double dose of MYPROTEIN pre-workout, I’d definitely still feel it afterward. 

My energy and focus would remain great for at least two more hours, allowing me to do some extra work after my resistance training session.

One thing I will say is there was some mild crashing after double-scooping MYPROTEIN pre-workout. It wasn’t too bad, but after I few hours, I felt like taking a nap to recharge.

What Are The Possible Side Effects

Depending on your personal tolerance and the dose you’re taking, MYPROTEIN pre-workout could cause some minor side effects such as:

  • Anxiety and Jitteriness: It is possible for you to feel nervous or anxious if you take two scoops of MYPROTEIN pre-workout.
  • Paresthesia: Beta-alanine is known to cause harmless skin itching at both 2 and 4 grams per serving.
  • Stomach Issues: High doses of caffeine can cause some digestive distress and discomfort, mostly in the form of nausea, bloating, gas, or diarrhea.
  • Insomnia: Depending on the dosage and the timing, MYPROTEIN pre-workout could interfere with your sleep quality and your ability to sleep.
  • Cardiovascular Issues: While not common, MYPROTEIN pre-workout (especially if double-scooped) can cause hypertension and elevated heart rate in certain individuals.
  • Crashing: High doses of caffeine could lead to energy crashes 4 to 6 hours after ingestion.

The only side effect I experienced regularly was the beta-alanine tingles. The itching was more pronounced when I was taking two doses of MYPROTEIN pre-workout, but in both cases, it would subside in 15-20 minutes.

But as I also said, some minor crashes were there, too. Those could be non-existent or quite hard-hitting for you, depending on your stimulant tolerance.

What Flavors Are Available And How Do They Taste?

MYPROTEIN pre-workout comes in five different flavors:

  • Blue Raspberry
  • Peach Ring
  • Pineapple Mango
  • Rocket Pop
  • Watermelon

The guy in my gym was using Blue Raspberry, so I asked him for a scoop so I could try it, and I have to say, it was as good as the Watermelon I bought.

Both flavors were quite distinct, and I could tell I was drinking a watermelon and raspberry-flavored pre-workout. Both were sweeter than I would’ve liked (I read somewhere people compare Pineapple Mango to Monster Energy Mango Loco), but I guess that’s what most people want anyway, so I can’t fault MYPROTEIN for doing that.

I couldn’t taste any metallic taste in either, which was great, but some aftertaste did linger for a bit if I didn’t wash it down with some water.

As far as mixing goes - it was perfect. Both one and two scoops of MYPROTEIN pre-workout dissolved in my shaker after only a few seconds.

Is It A Fair Price?

MYPROTEIN pre-workout is definitely a fairly priced product. At MSRP, it sits at $1.5 per serving, which is the median price for a pre-workout powder based on the data I have, which includes price points for nearly 100 different powders.

That said, MYPROTEIN pre-workout is commonly on sale, and if you manage to snatch it during that time, you will get a ton of value for your money. When I bought it for my MYPROTEIN pre-workout review, it was $25 for 30 servings, which is beyond great.

Who Is It Best For?

MYPROTEIN pre-workout is a great choice for anyone, but one could argue that it is best for beginners.

With 150 mg of caffeine per serving, MYPROTEIN pre-workout is ideal for trying things out. You could start with a single scoop to assess your tolerance and safely work your way up to two scoops, which would lead you to or close to your peak performance.

But at the same time, experienced gym-goers and even stim-heads could also benefit from MYPROTEIN pre-workout, provided they take two scoops instead of one.

Who Is It Not Good For?

MYPROTEIN pre-workout is considered safe, and based on its ingredients and their dosages, there really isn’t any healthy adult I’d say it isn’t good for.

On the other hand, any pre-workout, including MYPROTEIN pre-workout, can cause some issues and complications with certain individuals, such as:

  • Those Under 18: Pre-workouts are generally not advised for individuals under 18.
  • Pregnant and Breastfeeding Women: Limited research calls for caution to ensure safety for both mother and child.
  • Individuals with Heart Conditions: Pre-workouts may affect heart health, unsuitable for those with underlying heart issues.
  • Those with Anxiety or Mental Health Conditions: Stimulants can worsen symptoms of anxiety, depression, or other mental health conditions.
  • Individuals Sensitive to Stimulants: Some may experience jitteriness, nervousness, or heightened anxiety.
  • People with Insomnia: Caffeine may disrupt sleep patterns, circadian rhythm, and sleep quality.

Tips For Increasing Performance Using MyProtein Pre-Workout

If there’s one thing I learned from this MYPROTEIN pre-workout review journey is that this product was intentionally designed the way it was.

That said, there are a few tips I could give you to increase your performance using MYPROTEIN pre-workout

The first and the best tip I could give you is to double-scoop MYPROTEIN pre-workout. If you do, you’ll hit all the clinically efficacious dosages for all the important active ingredients.

Next up, eat a balanced meal 90-120 minutes before working out. Hit all your macros, but go for complex carbohydrates instead of simple ones.

But speaking of simple carbs, a heaving teaspoon of honey before hitting the weights is an awesome way to perk up your energy. You’ll get a hit of quickly digestible carbohydrates that will elevate your energy by a significant margin.

Caffeine

MYPROTEIN pre-workout contains 150 mg of caffeine per serving, which is not a lot, but enough to get you stimulated.

Caffeine works by “fighting” with adenosine for its receptors. Once bound, caffeine promotes wakefulness and alertness, effectively raising your energy levels and fighting fatigue.

In a pre-workout context, caffeine can:

  • Raise Energy and Alertness
  • Enhance Strength and Power Output
  • Heighten Focus and Energy
  • Promote Muscular Endurance
  • Speed-up Metabolism

Scientific backing regarding caffeine’s effects is essentially ironclad. All of the abovementioned effects have been proven on numerous occasions.

For example, a 2012 randomized, double-blind, crossover, placebo-controlled study showed that caffeine can increase “muscle strength and power output” above placebo levels up to 5.7%.[1]

Citrulline

L-Citrulline is a non-essential amino acid that works by promoting increased nitric oxide (NO) production in the body, which helps to relax and dilate blood vessels. 

This improved vasodilation can lead to enhanced blood flow and better nutrient delivery to muscles, effectively (and potentially) improving:

  • Temporary Muscle Volume
  • Endurance and Strength
  • Perception of Fatigue
  • Recovery and Muscle Soreness

Aside from massive pumps, supplementing with 8 grams of citrulline (which would be two scoops of MYPROTEIN pre-workout) was shown to lead to “52.92% more repetitions and the 100% of response in the last set”, as well as to a ”significant decrease of 40% in muscle soreness at the 24-hour” mark, per randomized, double-blind, 2-period study.[2]

L-Tyrosine

L-tyrosine is a non-essential amino acid that plays a crucial role in the production of several important neurotransmitters, including dopamine, norepinephrine, and epinephrine. 

It works by supporting the synthesis of these neurotransmitters, which are involved in mood regulation, mental alertness, and stress response.

When taken as a dietary supplement, L-Tyrosine can potentially:

  • Enhance Cognitive Function
  • Lower the Symptoms of Stress
  • Improve Exercise Performance

Truth be told, there’s still not enough sound data on tyrosine’s effects on exercise performance, so I wouldn’t count on it.

However, a study led by Louis E. Banderet, a U.S. Army researcher, has shown that treatment with tyrosine has “significantly decreased symptoms, adverse moods, and performance impairments in subjects.”[3]

MYPROTEIN pre-workout also contains 50 mg of theacrine, a natural compound found structurally similar to caffeine but with a different mechanism of action. 

Theacrine is believed to work by increasing dopamine levels in the brain, leading to improved mood, energy, and alertness, similar to caffeine, but with the advantage of reduced tolerance build-up and potential jitteriness.

In addition, theacrine is known to work great in synergy with caffeine, with one 2021 study showing that theacrine (50 mg) and caffeine (125 mg) combo is a “safe and effective product for improving cognitive performance.”[4]

MYPROTEIN The Pre-Workout Container with a Scoop

How I Felt When I Took MyProtein Pre-Workout

MYPROTEIN pre-workout review was divided into two categories - single scoop and two scoops.

Here’s how I felt during that time.

Within 15 Minutes

Regardless of the MYPROTEIN pre-workout dosage, I have felt beta-alanine tingles within the first 15 minutes. Of course, when I would double-scoop, I’d ingest 4 grams of beta-alanine, which made the itchiness more pronounced, especially around my neck and ears.

Thankfully, the dosing didn’t affect its duration by a lot, maybe 5-10 minutes tops, which was something I thoroughly enjoyed.

Now, the other thing I’d usually feel within the first 15 minutes is the energy surge when I’d double-scoop MYPROTEIN pre-workout.

The energy rush would hit me almost immediately, sometimes nearly to the point of jitteriness, so if you’re not used to >300mg caffeine dosages, please take it slow, as this could be quite unpleasant, too.

For me, however, this surge would just make me so eager to lift. I felt like I was going to burst if I didn’t get my body moving soon enough, which was pretty much the ideal way to feel before the resistance training session.

Within 60 Minutes

An hour after taking MYPROTEIN pre-workout, I would usually be on my third exercise, and depending on the dose I took, I’d feel either okay or like a superhero (you can assume which is which).

In a nutshell, a single scoop of MYPROTEIN pre-workout would allow me to lift with ease and go through my routine as I usually would, but two scoops would have me go the extra mile. 

For comparison, I usually train 4 or 5 sets of 8-12 reps, with the last set usually being 6-7 reps before failure, depending on the exercise. With MYPROTEIN pre-workout, I could easily do 10 reps on my last set.

Finally, my focus was pretty great, regardless of the dose, but I will say it was easier to stay focused early on in the session with just one scoop of MYPROTEIN pre-workout.

After 6+ Hours

I’ve already talked about how pleasant the immediate post-workout of MYPROTEIN pre-workout was, but the 6-hour aftermath was also good.

Now, I did feel a bit more down than usual after two scoops of MYPROTEIN pre-workout, but I would compare that to any of the crashes I’ve experienced previously. It was just a feeling of tiredness I usually feel if I slept horribly that night.

Other than that, I can’t say I felt anything 6+ hours after taking MYPROTEIN pre-workout.

I was able to fall asleep easily every time, and I wouldn’t wake up during the night. My stomach felt fine, I could eat well, and my mood was always the same, as far as I could tell.

How Does It Compare To Other Pre-Workouts?

MyProtein Vs Optimum Nutrition Pre-Workout

Optimum Nutrition Gold Standard pre-workout is a wildly popular pre-workout supplement due to its affordable pricing. However, even considering the price difference - MYPROTEIN pre-workout is a much better product than the Gold Standard.

Gold Standard won’t do anything for your pumps, as it only contains 750 mg of citrulline, which won’t work unless you weigh 20 pounds. Now, Gold Standard does have a bit more caffeine and an additional gram of creatine per serving than MYPROTEIN’s pre-workout, but neither of those can make up for the lack of citrulline.

Recommended

MyProtein

  • Caffeine - 150 mg
  • Citrulline - 4000 mg
  • Tyrosine - 750 mg

Gold Standard

  • Caffeine - 175 mg
  • Citrulline - 750 mg
  • Tyrosine - 250 mg

MyProtein Vs C4 Pre-Workout

To be perfectly candid, MYPROTEIN pre-workout wipes the floor with C4 Original.

In a nutshell, while their caffeine dose is identical, MYPROTEIN pre-workout contains more citrulline, more creatine, more beta-alanine, more theacrine, and more tyrosine than C4 Original.

I guess one could argue that C4 Original is better-tasting and is usually more affordable, but I don’t think neither taste nor cost makes up for the lack of sustenance C4 brings to the table.

Recommended

MyProtein

  • Caffeine - 150 mg
  • Citrulline - 4000 mg
  • Tyrosine - 750 mg

C4 Original

  • Caffeine - 150 mg
  • Citrulline (malate) - 1000 mg
  • Tyrosine - 0 mg

What We Have Taken Into Consideration For Giving You A Final Verdict

At this point, you might be wondering, "How can I trust this final verdict?" Well, let me share a bit about my background and expertise.

My Expertise In Supplements

Firstly, I've taken the time to educate myself and become a self-taught supplement expert, if you will. 

In other words, I've delved deep into the world of scientific research to extract as much knowledge on as many active compounds and dietary supplements as I could. 

While that may sound a bit too daunting of a task, I also have a background in pharmacology, which helps me understand all this data and tie it all together. My background also helps me weed out the data from badly designed or executed studies, which is very important when we talk about dietary supplements or other things that could impact your athletic performance or your general health.

As a cherry on top, I also became a certified sports nutritionist this year. While that didn’t necessarily make me more knowledgeable on the topic, it certainly did add to my overall credibility, the way I see it.

Reviewing Other Products

In addition to all that theoretical knowledge, I've been hitting the gym for nearly 10 years at this point, and during that time, I’ve experimented with pretty much every natural supplement you can think off.

So when you read my reviews and trust my verdict, you're not just getting advice from a science nerd (although I am one, big time), you're also getting insights and first-hand experience from someone who's dedicated years to health and fitness, and that counts for something.

MyProtein Pre-Workout FAQs

How do you best take MyProtein pre-workout?

The best way to consume MYPROTEIN pre-workout is to mix and drink one or two scoops of powder with 250ml of water 20 to 30 minutes before the workout.

How long does MyProtein pre-workout last?

MyProtein has a half-life of about 5 hours, but its main effects will usually subside 2 to 2.5 hours after drinking it.

How long does it take for MyProtein to kick in?

On average, it takes MYPROTEIN pre-workout about 15 to 30 minutes to kick in. For some, that may be a little while longer, but the effects should be in full swing within the first hour.

Is MyProtein made in the USA?

A portion of MYPROTEIN production occurs in the USA, in Shepherdsville, Kentucky. Still, the majority of products are still made in the United Kingdom.

Final Verdict

I’d like to finish off this MYPROTEIN pre-workout review by saying that I thoroughly enjoyed my time with this product, and I think you would, too.

MYPROTEIN pre-workout is a well-formulated supplement that’s designed in a way both beginners and advanced lifters can use it and equally benefit from it.

In addition to that, MYPROTEIN pre-workout is fairly priced, it tastes good, and it might just replace your daily creatine dose, provided you’re not too much of a hunk.

Now, if you don't like double-scooping, C4 Ultimate is probably a better option for advanced lifters who want effective dosages in a single serving.

we recommend this instead!
