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)

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

Taste great with excellent pumps

I got this to use as a pre-ride supplement for cycling. According to the labeling, it has no stimulants, and my heart rate would seem to agree. Tastes fine, no complaints there. Also does indeed seem to help with performance and endurance. But, non-stim or not, my sleep suffers dramatically any time I use it. I've used other non-stim products from other manufacturers and have not had that issue in the past, but something in here has me wired 9-10 hours post mulit-hour ride when I'm trying to doze off. Not like bouncing off the walls from a caffeine high type feeling, but I just can not fall asleep. Stopped using it for a couple of rides and sleep is back to normal. It probably won't affect everyone the same way, but it's been enough of an impact I wanted to make sure to mention it.

This was my first Stim Free Preworkout, and I'm not disappointed even after a 10 hour workday this formula give you the extra kick to move the weight and still be able to sleep. The value alone was a deciding factor, Not to chalky and dissolves easily. Perfect amount for a month. 5 STARS

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!

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.

Honestly feel obligated to write review I’ve tried ton of non stim pump pre workouts by some well known brands and this one for the $$ , taste & pump is by far the best!

Tastes great and it works! You'll feel the skin tingling like most pre-workouts but it's not bad. You'll definitely feel a pump in the gym, it helps!
