ProSupps Mr. Hyde Max Pump Pre Workout Powder, Blue Razz | Stim-Free Preworkout Supports Blood Flow, Muscle Volume & Endurance - Caffeine-Free Nitric Oxide Gym Supplements, 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

My favorite Pre with no stem! A MUST buy to have in your rotation, it doesn’t disappoints. I get a solid workout out with a nice pump and it tastes delicious with decent ingredients.

Dials in focus like no other and is probably the best tasting pre-workout catalyst i’ve ever used. The ingredients are solid, and this can be stacked with almost any other stimulant pre-workout out there. Doesn’t give any extra energy since it’s stim-free but does what it says it will do. The pumps are nasty and veins are likely to happen. My only gripe is that it gives me chest pain and a headache almost immediately after taking it. Worth it though — no pain no gain. Perfect for plumping up my succulent muscle fruits before hitting the beach.

If you’re looking for a preworkout that provides the pump, focus and energy you need without all the excess caffeine, this is the perfect non stimulant option. I drink energy drinks and take preworkout, which was putting me way over my suggested caffeine intake. Mr Hyde non stimulant preworkout allows me to still do both safely and get a great workout

Tastes great and provides great energy for morning workouts without the "head tingles" or stomach issues.

Guess I'm more sensitive than I thought; I'm generally sensitive to some things like caffeine, but this was my first time trying pre-workout. I was hoping caffeine free and stimulant free would help, but apparently I was wrong.. Tried just one dose, only drank half of it, and within 2-3 minutes I immediately felt the tingling and itchiness all over my body, which I've never felt before and it felt like I was on drugs.. Got restless and even trying to briefly work out wasn't helping, so I ran around to get nervous energy out, but my stomach started getting upset too so I couldn't move as much as I wanted-- and again this was within 3 minutes.. This really still felt like jitters to me, just in a different way than caffeine-- it was more within my body like moving didn't feel like it would change it... Can't imagine what it would be like if I tried the stimulant version... 😅 I could see how being extremely exhausted, this might actually help you feel invincible for a FULL workout, but I feel like this "half dose" is gonna last me like a week... Clearly pre-workout is not for me, but I think I was looking for a more general energy-booster for a physically demanding job all day, than specifically for an immediate hard workout.. Also for some reason after getting the nervous energy, I felt like crashing right away and had to lay on the couch, so yeah this isn't for me... Standing back up from the couch made the nervous energy return so I was on the couch for the rest of the evening.. I generally dislike powders just for the taste, and this does have a decent taste but the powder texture is definitely there too.. It is a nice price if you're not too sensitive... I just wanted something to boost muscles/energy where I can still work out outside of work and not sleep for 5 days straight-- but this aint that.. 😂 I was imagining more stable energy but this is more IMMEDIATE energy.

I was very impressed with this, I spent a while looking for a really good non-stim pre-workout because I like to work out late at night, and regular pre-workout sometimes hits me in a bad way. This stuff definitely gives me everything I want out of a pre-workout without the negative effects. Top of the shelf go to for me now

Great product, more focus on training.

I was specifically looking for a stimulant-free pre-workout and this delivered. It mixes well, gives a noticeable workout pump, and provides good training support without caffeine or jitters. Great option for those who exercise later in the day.

good👍️
