PROSUPPS Mr. Hyde Max Pump Pre Workout Powder - Stim-Free Preworkout Supports Blood Flow, Muscle Volume & Endurance - Caffeine-Free Nitric Oxide Gym & Fitness Supplements (Blue Razz, 20 Servings)

I drink it before walking and calisthenics. Keeps my head in the game so to speak. No jitters mixes well with a few shakes of the bottle. Taste and smells pretty good, worth the money I've tried most of the reasonably priced ones and for sugar free I settled on the punch and the berry.

My dad started taking this as a substitute for the caffeine version he used to drink for exercise. However, after hitting 70, he opted for something safer for his age.This is his all time favorite now and I’ve bought so many of these yet this blue one is his fave.Turns out it’s really effective, as I tried it and my wife as well. I was a personal trainer for many years and have taken every kind of caffeinated substance on earth lol and can confirm that this stuff works to get your focus in and has the necessary ingredients to sustain you through about an hour of training!Dissolves well and the taste is fantastic!

The Blueraspberry has great flavor and you get a great pump! No Stim is best as it doeasn't make me jittery and then crash! When it wears off you won't notice a change! Definetly worth the money! I would say this is one of the very best pre-workouts I have tried over hte years with no question!

Great taste and no caffeine. You get desired effective but your face will be a little itchy. Energy level is higher during a workout. No jitteriness and it’s a fair price for the product.

I’ve tried a lot of stim-free pre’s throughout the years and this is by far the best one. It’s a little tingly at first, but it fades within 15 minutes of working out (and I personally like the feeling). The pump is insane for no caffeine! I can go max weight for 10 plus reps even when I was feeling tired before the gym. It’s pretty impressive what this stuff can do. The best part of it all is this stuff doesn’t mess with my stomach at all. Almost every pre I’ve ever used made my stomach feel upset, sometimes to the point I had to stop working out. This pre doesn’t affect my stomach at all.My only complaint is the mix is too sweet. They should cut the sucralose in half (or just put real sugar) and add more citric acid. Or make a sour razz flavor. I’d buy that in an instant!

I’m not someone who writes reviews often but I felt this is necessary. I’ve been lifting since 2012. I don’t drink pop or energy drinks so my caffeine tolerance is low. I recently started drinking caffeine in the morning on the way to work and noticed now when I take my normal pre workout (ON) I have been crashing in the evenings. So I decide to try a non stimulant. This preworkout hurts more then helps in my case. I get zero pump, the skin crawling affect from the beta alanine is a lot (I hate this affect through all preworkouts though so take that with a grain of salt)…. But the worst part of all is the light headedness and jittery feeling. It’s so bad I can literally lift more without a supplement than with this. I can’t even concentrate on moving weight because I’m to busy focusing on staying stable. This product has mostly good reviews and honestly I don’t know how. But just let it be known… it’s not for everyone. After 3 attempts with this, it’s in the trash. I’d rather have evening crashes than deal with how this makes me feel.

UPDATE:Just received and started using this from my most recent subscription delivery. This is NOT the same product as I had before.Looking at the ingredients, I’m noticing that the formula has changed. You can even see in their product images that there are two different formulas. You can even see that the scoop/serving size has increased to get the same levels of the ingredients that are the same (11.2g vs 14.35g, a 28% increase!). I’ll try it for a bit longer to see if my body adjusts to it and if not, I’ll be looking for another non-stim pre-workout instead.Old review: While I have drank my fair share of caffeine in the past, I think that the amount of caffeine in pre-workouts these days is absolutely insane. I like to be able to control the amount that I am getting and I don’t feel like it actually does me that much more good for my workout. As such, I was looking for a no-stim solution and found this in my Amazon searches. The reviews looked great and I have to agree that I absolutely love the way I feel when I take this. I feel like the niacin burn comes on really quickly and then fades away really quickly, but I don’t feel like that affects my workout at all. Definitely worth a shot and at a great price point too. Give it a try!

Awesome taste. Best pre workout value. Great pump
