Overdrive your alertness and efficiency

For those who are looking for an adrenaline rushed, and want different experience in the gym, Mutant will be an ultimate challenge changer and workouts would change differently . The ingredients which should be researched before buying any pre workout. To be sure the body hits its max in gym without the crash midway or after gym sessions. But it's not for your average gym goer, or for people who want to exercise when they feel like it.

For me it delivers energy, focus, which is an absolutely must especially during hybrid training sessions. Weights/cardio

Not sure what it actually does

Thought I’d initially try as the product was £15 (nice & cheap) & had some decent reviews / but after almost using all servings, I can't recommend this to anyone.

Firstly the taste is nasty / after drinking it there's a weird tang taste in your mouth (kind of like drinking ginger beer) - after drinking, I don't “feel” anything. Considering it apparently has 330g of caffeine, nothing whatsoever.

Maybe I had a dud product, but its a shame as I get more enjoyment from the ABE pre workout My GYm Supplements sellls.

I'm throwing my tub out - don't waste your money

I will say that Mutant is not a bad brand - their mass gainer is very good, but this pre-workout is shockingly bad.

The product smells foul, but the flavour is actually quite nice once it's mixed in. That's it for the positives.

This is a high-stim preworkout that has very little effect. You will find the regular good preworkout ingredients on the list like Beta-alanine, but they are unfortunately all significantly underdosed to the point where they have no benefit. The preworkout relies heavily on a high (330mg) dosage of caffeine. Even so, the absorption of this product must be bad, because I hardly feel anything when I take this preworkout, and normally I get jitters when I have a double-shot coffee. "Mutant madness" had me yawning between sets.

The L-citrulline malate blend is underdosed by up to 1/4, and Beta-alanine is underdosed by more than half. These key ingredients are lacking - you might as well just drink a red bull before your workout. I would not recommend double/triple scooping as other reviews have suggested, because of the already very high caffeine content, which could cause severe cardiovascular damage.

This will jack you up

The name says it all. This stuff is madness. It's better then doing drugs. If your layz tired not motivated. Drink this. And I dare you to try to sit still. You'll be sent into orbit in no time. I don't use to work out I use it to get my day started. If you drink energy drinks and think they give you energy. That stuff is for baby's compared to this stuff. And way cheaper. No crash at all

It's flavoured caffeine. But works great with a bit of help.

Everything except the caffeine is completely underdosed, plus side to that is you don't have to worry about unexpected trips the bathroom mid workout. You don't get a mad crash mid workout. I train late afternoon, but it doesn't affect my sleep, it might be a different case if you train at night however.

Some flavours are better than others. The blueberry blast is my favorite.

To help it out a bit - I bought citrulline malate to add to it, which adds a nice tang to the flavour and gives the preworkout a good pump agent. (Use 8-10g's). You can buy a kilo of the stuff for just under £30 from peak supps on My GYm Supplements, it'll last you a few months.

I've been a preworkout junky for years, I've tried all sorts. This is all I've bought for the last 8-9 months now.

Insane workouts

Tried lots of pre workout in my time and I rate this highly. Workouts are great and no come down with this. Mixes well and tastes good

AWAKE

Recommend the lemon flavour as it will instantly make you feel awake because of how sour it is. It helped me when i would wake up at 4am, walk to the gym at 5 get there at 6 and the have the pre workout. Keeps me up all day for work. Not had a crash with it

The container say 225 G on it. But when I open my it had 125 G in it. And sashes of pillow pak

Heavy on the caffeine and bad taste

Not a great product not very nice to drink and if u go over your daily limit good luck sleeping. At times too strong even with only one scoop. Id more d half and half creatin it works best for m this way.

Pretty good.

Pretty good! Gives good focus, nice amout of energy, not the greatest pump, but it definitely helps with your workouts! Good value for money. Taste isn't too bad, either.

Strong Pre workout

This pre workout is definitely one of the best on the market. Our bodies of course are different and maybe the product is not working for everyone but it works good for me. I noticed an increase in my energy level and it gives me a good mood. Taste very nice especially if you mix in cold water.

Good product

Does the job! 💪🏻

Super strong

Super strong pre-workout, gives a slight tingle but plenty of energy!

Excellent Product at a Good Price

When it comes to pre-workouts I find that it can be pretty subjective, everyone has different tastes and may be looking for something different in terms of ingredients. I typically purchase some of the more expensive brands and go for the higher stimulant ingredients. This product has a suitable amount of stimulant ingredients and also great taste. This is the most reasonably priced pre-workout I have found and I continue to use it.

Super powers

Allows you to work twice as hard and long

Amazing.

Absolutely amazing product for a even better price. Absolutely love it. My son and I workouts are seriously improved useing this. It tastes amazing and no weird after taste like some brands. We both find we don't feel bloated or gassy after taking it. And neither are we as sore the next day after our workout, unlike some other brands. I highly recommend this for a increase in your workout 💪

Does What It's Advertised To Do

While it's listed as a pre-workout drink, I tend to blend it and take it into the gym as I'm working out and have a mouthful between sets of each exercise. I ordered the Orange Rush and am very satisfied with the flavour (cross between Orange Crush pop and Orange Kool-Aid (in my opinion). First time I took only 1/2 a scoop and found the while I was getting the same effect from it, the taste just wasn't there. I now use a full scoop and love the flavour it has.

As for the "effects" it has, for me, it didn't jack me up or give me that caffeine rush or anything like that. I found it did allow me to focus more intently on my workout and if you're looking for heart pumping, animal raging, add 50 lbs more per exercise stimulation, I'd recommend more hard rock music in your ear buds as opposed to "chemical stimulation".

I would definitely buy it again and will be sticking with the Orange Rush flavour since I already know I like it.

Best Pre-Workout Ever

My husband & I love the Mutant Pre-Workout and have always used the Iced Tea, but this Orange Rush is the best flavour by far!!

Doesn't cause the jitters and seems to just put you in a better 'headspace' for working out.

Love it - will continue to purchase!
