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)

ProSupps Mr. Hyde Max Pump is easily one of the best stimulant-free pre-workouts I’ve used. If you want serious pumps, better endurance, and improved workout performance without caffeine, jitters, or a crash, this delivers in a big way. The pump is where it shines. The combination of L-Citrulline, Arginine Nitrate (NO3-T), and Betaine creates noticeable muscle fullness, vascularity, and sustained blood flow during training. Workouts feel stronger, longer, and more productive. The beta-alanine gives you that pre-workout kick without relying on stimulants. What makes it top tier is how versatile it is. You can run it solo for clean stim-free training, take it for late-night workouts, or stack it with a stimulant pre-workout if you want even more intensity. The Informed Choice / banned substance testing is another major plus for confidence in quality. * Incredible muscle pumps and vascularity * Noticeable endurance boost during hard sessions * Zero caffeine — no jitters or crash * Great for evening training or stim-sensitive users * Transparent formula with well-known performance ingredients * Mixes well, tastes good, and holds up consistently If you want a pre-workout built for pumps, endurance, and clean performance rather than just stimulant overload, ProSupps Mr. Hyde Max Pump is top tier. It does exactly what a pump formula should do—and does it extremely well.

Bought this because I have somewhat elevated blood pressure, and still wanted something to help put some pep in the step in the gym. Right around the 20 minute mark I got that familiar skin tingle sensation in my face. Once I got moving it felt like it really delivered a clean, level boost of energy. There wasn’t that huge burst at the beginning, but I do feel that it helped through my entire workout, wearing off around two hour mark. Happy I bought it. Would purchase again. Oh and it tastes decent. 5 stars

I was very hesitant of this product due to having no caffeine. After one workout I was hooked. My face began to tingle and while I was in the middle of a set I began to feel the strength from a thousand gorillas. I blame this preworkout solely for allowing me to bench 315 even if it was only once. It does not taste chocky at all and it did not clump. I actually threw it in a regular water bottle and it disolved fine.

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 love this preworkout I cannot do caffeinated ones. They make me sick. This one taste amazing and makes my workouts go smooth and gets me through them.

Perfect if you go to the gym at night. Still has a little bit of a tingle but nothing terrible. Still able to take at night and not have to worry about staying awake. Highly recommend.

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.

Best stim-free workout I’ve used. Kicks in about 5-10 minutes. Mixes easily with zero clumping. I’ve been having better workouts. The ingredient combination works well for me as I workout typically in the evenings. Doesn’t affect my sleep at all. Will be continuing to buy because price is great as well.

Great product, more focus on training.

good👍️
