No-stim pump help with glycerol, beta-alanine, and everything out in the open on the label.

Metabolic Nutrition Stim-Free Pump is a simple no-stim pre-workout that aims to make your sessions feel fuller, go longer, and stay strong without caffeine. The idea is straightforward: mix nitric oxide boosters, hydration helpers, and burn fighters so you get a solid pump, handle more sets, and train anytime without issues. Beta-Alanine is at 3,000mg, right below the usual 3.2g daily mark from studies. It boosts carnosine in your muscles over time, and carnosine fights the acid buildup during intense workouts. That's key for high reps, supersets, quick rests, or conditioning where the burn stops you. 3g per scoop is a good daily amount, but stick with it—it's not a one-time wow, more like building up for better endurance. Citrulline Malate 2:1 is at 3,000mg. Citrulline turns into arginine in your body and helps nitric oxide for better blood flow—better than straight arginine, which is why it's common in pump products. Dose-wise, it's under the 6-8g from top studies, so expect some flow and feel boost, but not the max clinical level. Glycerol Powder at 3,000mg is a cool part here. It helps hold more water in your cells, leading to fuller muscles, easier training, and a lasting pump if you drink enough. At this dose, you'll notice it, especially

MN Stim-Free Pump by Metabolic Nutrition contains 3000mg Beta Alanine, a effective dose for muscle recovery and growth.

Key Highlights

  • 3,000mg Beta-Alanine gives you a solid daily dose just shy of the classic 3.2g mark. It loads up carnosine in your muscles to fight acid buildup, making those repeated tough sets feel easier to push through over time.
  • 3,000mg Citrulline Malate 2:1 hits the arginine-nitric oxide path for better blood flow and that workout pump. It's below the big 6-8g study doses, but still adds basic NO support in a no-stim setup.
  • 3,000mg Glycerol Powder sets you up for better cell hydration and that full look when you drink enough water. This is what drives the dense, swollen muscle feel a lot of folks love in pump products.
  • 725mg Cluster Dextrin® is the trademarked carb from Glico Nutrition. It's great for quick emptying from your stomach without feeling heavy during workouts, even if this dose is more supportive than a full carb blast.
  • 250mg Agmatine Sulfate adds to the pump with more nitric oxide help. Not a huge dose on its own, but it fits right in with citrulline for blood flow focus.
  • 10g active formula in a 10g scoop means no junk fillers. Every bit is working, which is tough to find in a market full of hype and weak builds.
  • No prop blends here—every ingredient and dose is right on the label. That openness lets you check it against real studies instead of wondering what's in some mystery mix.
  • No-stim setup works for late-night lifts, double days, or folks sensitive to caffeine. Advanced users can toss in their own caffeine without being stuck with a fixed amount.

Who Is This For?

  • Bodybuilders chasing pump, volume, and that full look over max buzz. Glycerol, citrulline malate, and agmatine make muscles feel swollen, while beta-alanine helps longer sets before burn wins.
  • Evening gym folks wanting pre-ritual without messing sleep. No stims mean late-day use keeps recovery solid and you ready tomorrow.
  • Athletes with coffee or drinks already, controlling total stims. This adds pump and endurance from beta-alanine, glycerol, citrulline without extra caffeine.
  • High-volume trainers doing supersets, drops, short rests. 3g beta-alanine fights rep burn, glycerol keeps muscles feeling full longer.
  • Folks who hate shaky, anxious pre feels. This focuses on workout quality and muscle vibe, not overdrive, for hard training without the hype.
  • Cutters wanting sessions and body to feel full on low cals. Glycerol hydration and citrulline/agmatine pump help fight that diet flatness.

How to Use

Mix 1 scoop in 12-20 oz cold water, drink 20-30 minutes before lifting. Go higher on water to max the 3,000mg glycerol— it needs fluids to shine. Shaker's best over stirring since glycerol and carbs mix better shaken. Empty stomach speeds the feel, but a light meal 60-90 minutes prior works if you like food before. No caffeine listed, so no tolerance check; newbies, try half scoop for tingles and stomach test. Stacks with creatine, electrolytes, or caffeine as needed. No cycling required—no stims to get used to—and daily use is best for beta-alanine perks. Keep it sealed cool and dry; glycerol pulls moisture.

What to Expect

First 0-10 minutes, it's mellow—no stim rush. If beta-alanine hits you, tingles might start on skin, like face or hands. 10-20 minutes, hydration and early flow kick in, if you mixed with enough water and aren't dry. 20-40 minutes is prime: muscles fill up, warm-ups pump better, session flows smooth. 40-90 minutes, it's about keeping quality up without peaks or crashes, no stims to drop off. Days 1-7, pump and feel stand out; weeks 2-4, beta-alanine builds carnosine, making hard sets less brutal.

Key Ingredients

  • Beta Alanine — 3000mg — Buffers the burn so hard sets last longer
  • Citrulline Malate 2:1 — 3000mg — Supports nitric oxide for visible pump and flow
  • Glycerol Powder — 3000mg — Drives muscle fullness through workout-focused hydration support
  • Cluster Dextrin® — 725mg — Light training fuel with low stomach heaviness
  • Agmatine Sulfate — 250mg — Complements pump pathways for enhanced workout fullness

Frequently Asked Questions

Does Metabolic Nutrition Stim-Free Pump contain caffeine or other stimulants?

No. Based on the disclosed active formula, this product is built without caffeine and without a traditional stimulant profile. Its effects come from 3g beta-alanine, 3g citrulline malate, 3g glycerol powder, 250mg agmatine sulfate, and 725mg Cluster Dextrin®.

What should I feel from this formula during training?

Most users notice fuller muscles, better workout hydration, and a more pronounced pump rather than a rush of energy. Some also notice beta-alanine tingles from the 3,000mg dose, especially when taken on an emptier stomach.

Is 3,000mg of citrulline malate enough for a strong pump?

It is a useful dose, but it is below the 6-8g range most often associated with the strongest citrulline malate research on pump and exercise performance. In this formula, citrulline works as part of a system alongside glycerol and agmatine rather than carrying the entire pump experience by itself.

Why is glycerol included at 3,000mg?

Glycerol is used to support hyperhydration and cellular fullness, which can make muscles feel denser and more swollen during training. At 3g, it is one of the defining features of this formula, but it works best when you deliberately drink enough water with it.

What is Cluster Dextrin® doing in this product?

Cluster Dextrin® is a trademarked highly branched cyclic dextrin carbohydrate known for quick gastric emptying and good tolerance around exercise. The 725mg dose here is modest, so it is more of a supportive addition than a full carb-fueling dose.

Can I stack this with coffee or a caffeinated pre-workout?

Yes. Because this formula is stim-free, it is easy to combine with coffee, caffeine capsules, or another stimulant source if you want energy on top of pump support. Just keep your total daily caffeine intake reasonable and avoid duplicating ingredients if stacking with a full pre-workout.

Do I need to take this every day, or only before workouts?

You can use it only before training if you mainly want the acute pump and hydration effects. But for beta-alanine, daily use is better because its performance benefits come from cumulative carnosine loading over time, not a single serving before one workout.

Is this formula beginner friendly?

Yes, especially for users who do not want to start with caffeine-heavy pre-workouts. The label is simple and fully disclosed, though beginners should know that beta-alanine can cause harmless tingling and that the product is more about workout feel than stimulation.

How does this compare to more advanced non-stim pump formulas?

This is a simpler, more basic stim-free pump formula. Its strengths are transparency, stackability, and a solid 3g glycerol plus 3g beta-alanine backbone, while its main limitation is that citrulline malate at 3g and agmatine at 250mg are below the more aggressive doses seen in premium non-stim formulas.

Are there any inactive ingredients or allergen concerns listed?

The provided formula data lists no inactive ingredients. The product is also identified as vegan, gluten free, and non-GMO, which improves compatibility for many users, though anyone with highly specific sensitivities should still verify the current label on the physical package.

A bit disappointed in our most recent order.
Style: Large, Size: 3 Chews, Style: Large, Size: 3 Chews
**update 11/15** Native Pet reached out directly and offered a full refund. I appreciate that they took my feedback seriously and took steps to resolve the issue. We love Native Pet and have gotten several other products that our pup not only enjoyed but also all did what they say they do. Native Pet does make high quality goods for pets and we will continue to be customers. I did not enjoy writing my 3 star review but I wanted to make sure that the brand that we love was aware we didn’t get what we were expecting for the first time in over a year of purchasing. I’m upping my review to 4 stars, but please know that these yak chews are seriously amazing if you can ensure you get the right size for your dog!! —Prior review— Before our most recent order I would have given these 5 stars. We have been buying these yak chews since we adopted our rescue girl in July 2022. These are by far the best “bones” we have been able to find since they are fully edible and can transform into crunchy treats when they get to the end of their life, and they do not upset our baby’s tummy. We love these and have the 3 pack on auto ship. However, our most recent order received on 11/9 is a disappointment. We originally bought the medium chews when we first got our dog because she is medium sized and 45-50lbs, but she turned out to be a big chewer. The medium were too small for her and she was able to bite off large chunks and go through them too fast. We switched to the large which have always been thicker and just a little bit longer so she went through them a little slower and couldn’t get as many big chunks off. Our 11/9 order contained what appears to be the same size as the medium chews, which we don’t get anymore for the reasons stated above. I added a photo of what we received next to pieces left from our prior order. You can clearly see the pieces from the prior order are thicker (circled in green). I didn’t spend $28 to get medium sized yak chews. I understand they can all be slightly different sizes even within the same package, and we sometimes get thicker/thinner/darker/lighter chews, but these are just very SMALL compared to the other large chews we’ve received over the past year. It seems strange that I would suddenly need to start purchasing the extra large chews to get the same substantial size as the large ones I was getting before, unless there’s been a change in the product design itself. I really hate leaving negative reviews. I prefer to only leave reviews when I have a great experience because I think it’s important to share those things rather than complain. If I really have an issue, I usually reach out to the seller if I can. In this case, I can’t find a way to contact the seller to ask if there was a change in the product or if this was an error but I guess I can go through an Amazon customer service rep if needed. This product can’t be returned which is typical of food-like items, but I would like to know why this order seems so inconsistent from what we’ve gotten in the past.

Dogs LOVE and My Belongings Are Safe(r)
Style: Medium, Size: 10 Chews
I have two small dogs (~13LBS) and they LOVE to chew. Those two will take anything new and chew it. ANYTHING. Especially if it's plastic. The damage to things like eye glasses, medication, valued toys, etc has been significant. They have 50 toys, but nothing is better than good old fashioned chewing for these two. Desperate for anything that will keep their attention long enough to distract them from my stuff, I gave these a try. They LOVE these things! Bonus Fun - give virtually identical chews to each dog and instead of them each happily chewing, they like to torment each other by taking the chew from the other and instead of just moving on to the other, they wrestle each other for possession of whichever chew has been identified as "IT" that day. Many hours of fun! The best part, they always have something hearty to chew, which makes them less likely to steal my stuff. I buy the Medium and they last about a week since they are small dogs. So, while these are pricey, they do last a while for my little guys. I have tried a few other brands of Yak Chews and these ones seem to last the longest. Another brand I got, they were able to eat the entire one in an afternoon instead of lasting a long time like these, so they are definitely higher quality and sturdier than other brands.

Portable, no smell, keeps my dog busy
Style: Small, Size: 15 Chews
I started buying these for my dog a few years ago at the recommendation of the guide dog school trainer. They are fantastic! They are hard and almost seem like a bone, but they have no smell and are nice and dry and not greasy. They are easy for me to put in a bag and take with me if I need to keep my dog busy or quiet while I am doing something else, such as when I take my dog to a restaurant or speaking engagement as he can be kind of high energy. My guide dog is a yellow lab and weighs about 70 pounds. I keep the small ones handy, and it takes him about 15 up to 30 minutes to finish it. The larger sizes are good if you need something that will last longer. These have been absolutely a great resource for my dog and I highly recommend them!

Very good chew and great customer service
Style: Medium, Size: 10 Chews
We have been ordering Native Pet's medium Yak chews from Amazon for some time now as a subscriber item, averaging a 10 pack about every 3 weeks. We chose the Native Pet brand based on the many positive reviews and had been very happy with our choice with the exception of our most recent 2 orders. As with any natural product, there are differences in the chews in every package. Since the chews are very hard, we prefer the ones that are just a little "softer" and wear away as our dog chews them versus the slightly more brittle chews that can have larger chunks break off, potentially presenting a choking hazard. With that said, most of the chews we received were of the former consistency and hardness until we received a pack where the screw top was very loose and the foil seal was compromised which may have allowed them to dry a bit more than normal. We gave the chews to our dog (I probably shouldn't have in retrospect) and EVERY chew was now brittle and broke off large chunks. The next order arrived in a large envelope from Amazon and the contents were completely out of the package with the screw top completely off, a black powdery substance at the bottom of the envelope and inner portion of the screw top, and the moisture packet and 10 chews were loose in the envelope. This time they went into the garbage. I decided to call Native Pet and let them know there may be a rough handling issue at Amazon, or an issue with their shipping... or whatever.....but that there was definitely a customer issue. I received a text message almost immediately from Pat Barron at Native Pet giving me a direct email to communicate the circumstances and to attach some photos. Pat was appreciative for the notification and photos, genuinely concerned with the quality of their product, and graciously offered a replacement as a gesture of good will from Native Pet. It was outstanding customer service from an individual and company proving they actually care for you as a customer and for your continued satisfaction with their product.

Dog loves them, but don't leave them unattended
Style: Small, Size: 5 Chews
My pug loves these. Be careful, they sometimes crumble into shards, so always be present. My dog has swallowed some and threw them back up.
