Mr. Hyde Max Pump Pre Workout Powder, Fruit Punch | 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 consistentlyIf 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.

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

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.

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!

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

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.

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

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👍️
