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)

Amazing taste. No caffeine so its good for people who lift at night. Great pumps from this pre workout. 20$ price point cant be beat for preworkout

Tastes good. Seems to work. I like it because of no caffeine because I workout at night.

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.

Good Doesn’t hit like caffine But smooth energy Felt dizzy Pump is average

It delivers for reps or cardio. Mixes well, doesnt clump and grit like TWpump. Plus, this product has a pretty taste.

UPDATE: Just received and started using this from my most recent subscription delivery. This is NOT the same product as I had before. Looking at the ingredients, I’m noticing that the formula has changed. You can even see in their product images that there are two different formulas. You can even see that the scoop/serving size has increased to get the same levels of the ingredients that are the same (11.2g vs 14.35g, a 28% increase!). I’ll try it for a bit longer to see if my body adjusts to it and if not, I’ll be looking for another non-stim pre-workout instead. Old review: While I have drank my fair share of caffeine in the past, I think that the amount of caffeine in pre-workouts these days is absolutely insane. I like to be able to control the amount that I am getting and I don’t feel like it actually does me that much more good for my workout. As such, I was looking for a no-stim solution and found this in my Amazon searches. The reviews looked great and I have to agree that I absolutely love the way I feel when I take this. I feel like the niacin burn comes on really quickly and then fades away really quickly, but I don’t feel like that affects my workout at all. Definitely worth a shot and at a great price point too. Give it a try!

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!

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
