Really Good Preworkout
Great taste and results. Gives you some extra energy from the aminos but no jitters. Love the tingle you get when lifting heavy.

Good stuff, tastes great.
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.

Great product but slight itchiness in the face
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.

This is the best stim free pre I’ve ever used.
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!

Excellent Product !
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!
Jake Booher –
Just ok
Not the worst, was very clumpy no matter how much I mixed it and the taste was okay, but taste is obviously subjective. Performance wise this is great, which is why I still gave it three stars.

The real deal
I’ve taken my fair share of pre-workouts both caffeinated and stim-free. But I needed something new that was both caffeine and creatine free. I just needed a good pump and energy for my evening workouts. Hyde Max Pump is it. Had a little tingle at the beginning but not bad. Then started my workout. Lifted all the same weight I’d done just the week before. I got 4+ more reps for every exercise. Normally I get distracted and lose focus and motivation in my workouts. With Hyde my workout flew by and I had a nice pump and sweat going. Didn’t want to stop. Flavor was good, but it’s only 6 oz so flavor doesn’t really matter. Just slam it if you don’t like it.

Jittery and light headed
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.
