Madness | Ultra-Concentrated Pre-Workout Supplement | 360mg Caffeine, 4g Pump & Performance Blend, Beta-Alanine, Energy & Focus | 30 Serving | Blue Raspberry

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 💪

I’ve tried many pre-workout brands and flavours over the years and found the Mutant pre-workout to offer a great flavour, without a lingering, chemical taste, that offers results. You don’t get what I’d describe as an unpleasant pins and needles sensation, but you do get a good energised feeling and strong pump during your workout that lasts long after your training session.

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 amazon, 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.

I’ve taken other brands of pre workout a lot over this last year and stopped feeling the affects but.. wow… May Ronnie Coleman have mercy on my soul. I purchased this as a last ditch attempt of using pre workout after night shifts. At first, a delicious taste of pineapple, followed by a beautiful aftertaste of… well… pineapple. What followed after around 10 minutes, however, can only be described as being punched in the face by Mohammed Ali, followed by a roundhouse kick to the side of the head by Chuck Norris, whilst giving you the feeling of being more locked in than a prisoner on a life stretch for crimes against caffeine. The pumps, the focus, the energy- wow. All insane. Warning- will make you feel like you’ve been attacked by microscopic people with teeny tiny pitch forks all about your face for at least 10 minutes. It does pass. Enjoy

First thing I noticed was the fact the tub was less than half full! no real surprise as most pre workouts aren’t full when new. But this one was more than any other I’ve used. Also noticed the tub was smaller than other brands I’ve used before. I weighed the contents on my scales and it was the weight stated in the tub. Other brands I’ve tried have more content in the tub, so make sure you check other brands before purchasing this one. There isn’t much of it and doubt it will last me more than a month. I used one scoop and it was as suggested and the effect was ok, I tried 1.5 scoops the next workout and could definitely tell the difference. I had the pineapple version and really liked the taste, better than all the others I’ve tried before. I’ll give it a few weeks to see if I’ll purchase again.

This is one of those ones that give you that good boost and the pins and needles on the inside if you don't move lol.

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.

Great works well

This is the most powerful pre workout i had

The best flavor

Tastes good and has decent contents, but feels weak for someone with a somewhat high tolerance. Recommended for people not too familiar with pre workout.

Good stuff, gets you going Was delivered covered in a black sooty dust from sitting on a shelf for ages I'm guessing

I used to use this preworkout all the time, then I switched brands for a while. Still love it! Works great, and tastes awesome.
