Axe & Sledge DEMO DAY: Workout Carbs to Construct Your Body

Axe & Sledge Demo Day

It’s DEMO DAY. Time to train like crazy, down your muscles, and build them better than ever before!

Last week we gave you an update on Seth Feroce’s brand, Axe & Sledge, and their killer stim-free pre workout pump formula, Hydraulic. Now we’re back with another one of their products, the supplemental carbohydrate powder in Demo Day.

Demo Day: Mixed-GI, Fast-Acting Carbs with Hydration Pumps and Glucose Shuttling!

Just as with Hydraulic, Demo Day features an open label, efficacious doses, and patented ingredients. Not just a couple, over half of the ingredients in this one are patented, keeping the status quo that Seth has set for his products only containing premium ingredients. After all, you can’t fuel the hardest workers in the gym with low quality ingredients and cheap carbs!

We’ll be giving you a breakdown of this rather unique supplement and its well dosed ingredients, but before we dive in, be sure to sign up for PricePlow’s coupon driven deals so you don’t miss out on any discounts, and sign up for Axe & Sledge alerts to stay up to date on the latest and greatest with this awesome brand.

Axe & Sledge Demo Day Ingredients

  • Carb10 (15,000mg)

    Axe & Sledge Demo Day Ingredients

    Now this is how you carb up and train! On top of the low-GI, fast-digesting carbs, you get two glucose disposal agents to drive them in, and hyper-hydration water-pump agents!

    Starting off, we have a big 15g dose of Carb10, the new, low glycemic index carbohydrate form from Compound Solutions, which is actually starch derived from peas.

    The advantage of this new carb form is that it has the dual-sided benefit of being low glycemic, while simultaneously also being fast absorbing. Essentially, you can quickly top off your muscles with glycogen, which will yield some performance benefits, but you also don’t have to worry about spiking your insulin crazy amounts, which isn’t necessary for hypertrophy (muscle building) anyway! But if you can keep a nice and steady prolonged carb drip, you can both build muscle and fuel an ultra-long workout, yet not induce fat storage.

    With an osmolality of just 30 mOsm, this product is marketed to help by “providing 82% lower insulin response and 27% lower blood-sugar response,” as per Compound Solutions information.

    This is the first of our patented ingredients in this list, and don’t forget, this is a carbohydrate, and 15g of it at that, meaning this also accounts for about 60 calories in the body.

  • Cluster Dextrin (11,000mg)

    HBCD Cyclic Cluster Dextrin Benefits

    The Borg Scale shows the rate of perceived exertion, meaning Cluster Dextrin makes it feel like you’re working less hard than maltodextrin![3]

    The leading carb in the industry for performance has been Cluster Dextrin, a trademarked form of Highly Branched Cyclic Dextrin (HBCD). HBCD is rapidly digesting, and also has the benefit of causing little to no gastrointestinal upset. Carb sources like dextrose, maltodextrin, or sucrose have slower gastric emptying rates, which lengthens the time before the carbs can actually get to your muscles. Thankfully, HBCD fixes this issue.

    In addition, HBCD has a high molecular weight, yet also has very low osmolality. Much more simply, it gets through your digestive system and into the muscles quite quickly.[1] This quick processing allows your intramuscular glycogen stores to be quickly refilled, which has the benefits of increased performance, and a decrease in delayed onset muscle soreness.[2,3]

    Anecdotally, pre, or intra workout carbs give better performance, and nastier pumps, something we know Seth is all about from our Hydraulic review. There’s 2 patented ingredients already!

  • L-Taurine (2,000mg)

    A rather unique (and awesome) ingredient in a carb blend, we have 2g of taurine, an organic acid that functions as an osmolyte, helping the movement of water between cells. This gives us the benefits of endurance and performance boosts.[4] And, it turns out taurine has much more acute effects from doses as low as a gram than we ever thought before.[5]

    Axe & Sledge is for the Hardest Workers in the Gym

    Taurine is important for vital functions as well, and is necessary to keep the muscles, brain, and heart healthy, making this a great addition for general health. And if you are staying well hydrated, you will also notice some nice water pumps from its osmotic action as well, especially when paired with another similar ingredient coming up next.

  • GlycerPump (2,000mg)

    Coming in with our third patented ingredient, we have the premium version of glycerol, known as GlycerPump. Thanks to the scientists over at Pinnacle Ingredients, GlycerPump is here to fix the issues of yesterday’s glycerol monostearate. With their spray drying technique, we get high yield (65%) glycerol by weight, and next to no clumping, an issue that absolutely plagued glycerol containing products in the past. Thanks to GlycerPump, we have high yield and no clumping, drastically improved the quality of products utilizing it.

    As for the performance enhancing aspect, glycerol acts as a sponge within your muscles, and draws water up into the muscle fibers. This results in a hyper-hydrated state for us.[6] Just as with taurine, this will greatly enhance our water pumps. But, to reap all of the benefits from the taurine + glycerol combo, you have to be sure to be intaking plenty of fluids both pre and during your workout.

  • Palatinose (2,000mg)

    Seth Feroce Carbohydrates

    How Seth Feroce does carbohydrates

    Our last carb source, and our fourth patented ingredient, in this blend is Palatinose, which is yet another low glycemic index carb form, which comes from beet sucrose, and is about 50% as sweet as straight, regular sucrose.[7] Using carb sources like this prevents hypoglycemia, which is a condition of low blood sugar stores, which commonly happens after intense training.[8]

    Palatinose also creates lower plasma insulin amounts than inferior carb sources, leading to more fat oxidation and less glycogen usage.[9]

    Every time we see Carb10 combined with HBCD and/or Palatinose (in this case we have both), we love it. All angles safely hit, and insulin won’t be so elevated that you’ll never burn fat.

  • Cinnamon Bark (50mg)

    Cinnamon Bark makes a great addition to a carb product, and is something we generally see in wellness supplements or even glucose disposal agents. This is because cinnamon has some great effects when it comes to blood sugar levels. It has been shown to reduce blood glucose levels, enhance lean body mass, and even help burn body fat.[10] It especially plays well with our carbs and the next, similar ingredient we have here.

  • Alpha Lipoic Acid (50mg)

    Our last ingredient is Alpha Lipoic Acid, which is a fatty acid naturally made by the body and stored in the mitochondria. It acts as a powerful antioxidant, and is also involved in energy production as well. Alpha Lipoic Acid has research showing it increases energy expenditure,[11] as well as working to reduce appetite and fasting blood sugar.[12,13]

Flavors available

Seth Feroce Demo Day

Those are some big melons you got there. Seth and the team at Axe & Sledge are having way too much fun!

Below is an up-to-date list of the Demo Day flavors available.

    Mike has been sent the naked (unflavored) version to mix in, and he’ll have a review with a glucose monitor posted to the top of this post soon.

    Sweetener added to flavored versions

    Important to note is that the flavored versions do have some extra sucralose added, but if you don’t want that, then just stick with the Naked version, which doesn’t.

    Final Thoughts: More than just a carb powder

    Axe & Sledge

    See all Axe & Sledge supplements and news on PricePlow, and note that 10% off coupon we have!!

    Certainly Demo Day is bringing in some serious firepower with three high-quality, low-glycemic carb sources, but this product is more than a one trick pony. With added ingredients for some water pumps, as well as some glucose regulators, it seems Demo Day came into the market with some great innovation that we’re happy to see. Who else but Seth himself to add pump ingredients to his carb supplement.

    This is literally exactly how we would design a carbohydrate supplement if tasked to do it ourselves. Looks like we don’t need to at this point, because Seth has the carb game handled.
