Granite Supplements Arc Reactor – John Meadows’ Pre Workout!

Granite Supplements Arc Reactor

The Mountain Dog John Meadows has launched a new supplement brand titled Granite Supplements headlined by their dynamite pre workout Arc Reactor.

After leaving Prime Nutrition, the masses were wondering what would happen to a key contributor to the Prime Nutrition formulas — John Meadows, a.k.a. The Mountain Dog.

John was quiet for a while, at least to us on the outside. But, the Mountain Dog wasn’t wasting his time away — not even close. Instead, he was busy with the creation of his new brand Granite Supplements, and he’s gettin after it in a serious way here!

The brand has just debuted, but they’ve got a full arsenal of supplements ready to help you crush your fitness journey. Today, we delve into Granite’s monster pre workout Arc Reactor which will transform you into Iron Man for you workouts!

This is one hell of a unique pre workout, and it’s got a few new ingredients, so get ready!

But until Granite Supplements are available in our stores below, find them at, and then let’s rip into this one!

Arc Reactor Ingredients

The mountain dog isn’t messing around with his pre workout. It’s a beast in the truest sense. Each serving weighs in at an impressive 25g and packs everything you need in one scoop – pumps, muscle building, and energy!

After you read this, you’ll understand why this was rated one of the Best Pre Workout Supplements for Pumps!

  • Prime Pump Performance Blend

    • Citrulline & Citrulline Malate (6g)

      Granite Supplements Arc Reactor Ingredients

      Arc Reactor is incredibly well dosed and provides all you need to power through even the most daunting workouts.

      Starting off Arc Reactor’s powerhouse list of ingredients is a total of 6g L-Citrulline from a combination of pure L-Citrulline and Citrulline Malate 2:1.

      This is certainly a new spin on putting Citrulline in a pre workout, but the end result is all the same — significantly better performance and monster PUMPS! Citrulline is a potent vasodilator that enhances nutrient transportation as well as energy production, making for incredibly productive workouts.[1,2,3,4]

      And we’re only getting started!

    • HydroMax® (1.5g)

      Arc Reactor furthers the pumps by adding in a nice 1.5g dose of HydroMax® 65% Glycerol.[5] This high yield form of glycerol improves hydration, performance and “water-based” pumps due to its ability to “super saturate” skeletal muscle cells with water.[6,7]

      Due to this ingredient, drink plenty of water with your Arc Reactor – it will work better!

    • Nitrosigine® (750mg)

      Developed by Nutrition21, Nitrosigine is an enhanced form of the age old N.O.-booster L-Arginine. It’s silicate-bonded to increase the bioavailability and improving Arginine’s ability to actually elevate nitric oxide levels in the blood.

      Research using the compound demonstrated it not only immediately boosted N.O. levels, but also increased baseline N.O. levels — meaning Nitrosigine has the remarkable ability to sustain elevated N.O. levels for up to two weeks![8]

    • VasoDrive-AP™ (254mg)

      AmealPeptide Logo

      AmealPeptide is a one-of-a-kind tripeptide derived from casein protein that improves vasodilation and supports healthy BP levels.

      VasoDrive-AP is a clinically tested, proprietary ingredient derived from casein (yes, as in the protein!). You may also seen it referred to as AmealPeptide® (VasoDrive-AP is Granite’s trademarked form of the ingredient).

      VasoDrive-AP is produced through a patented fermentation and enzymatic process that “liberates” two key tripeptides, Valyl-Prolyl-Proline (VPP) and Isoleucyl-Prolyl-Proline (IPP), (consisting of the three amino acid chains valine, proline and isoleucine). VasoDrive’s unique processing provides VPP and IPP in levels not practical to attain through regular dairy consumption.

      As for what’s it’s doing in a “pump blend,” VasoDrive-AP inhibits an enzyme that leads to blood vessel constriction. By inhibiting this enzyme, it promotes vasodilation, increasing blood flow, and lowering blood pressure[8,9,10] — all leading to bigger, badder pumps! Interesting!

      Those worried about possible GI distress since VasoDrive-AP is derived from milk, fret not, as VasoDrive-AP contains less than 0.05% lactose.[12]

  • Strength/Endurance/Anti-Fatigue Performance Blend

    • Creatine Monohydrate (3g)

      Granite Supplements Line

      Granite Supplements has a full spectrum of products to address all of your supplement needs.

      The oldest muscle builder around. Next to caffeine, creatine is perhaps the most studied single ingredient in the supplement world. It’s proven time and again to work for improving power, strength, performance, and lean body mass.

      The Mountain Dog isn’t screwing around with any of those “cutesy” forms of creatine like HCl or MCC — he’s included the tried and true form, creatine monohydrate, the form with the most proven research behind it!

    • Betaine Anhydrous (2.5g)

      Another popular “daily muscle builder” is betaine, a.k.a. trimethylglycine. Betaine works synergistically with creatine to support creatine production in the body as well as enhance overall ATP production.[13,14]

      On its own, betaine has been shown  to improve hydration, power, strength, and endurance.[15,16,17] This leads to significantly better workouts which ultimately translates into more muscle!

      Creatine and betaine are set for the day now!

      And guess what now – your daily muscle-building needs for creatine and betaine are both now set at a full scoop – DONE.

    • CarnoSyn® Beta Alanine (1.8g)

      Granite Supplements Arc Reactor Stromtrooper

      Even the fearsome stormtroopers are digging Arc Reactor!

      Beta Alanine is a carnosine precursor[18], that limits lactic acid buildup in skeletal muscle. BA helps prevent the “burning” sensation from hitting too soon during extended working sets, causing you to stop your working sets early.

      Furthermore, Beta Alanine also increases endurance, power, and time to exhaustion.[19,20,21] Since this is below the clinical dose of 3.2g, you shouldn’t have to worry about any tingling or paresthesia – but you may want to get another dose of BA in at the opposite end of your day to get the full effects from it.

    • L-Ornithine L-Aspartate (1g)

      L-Ornithine L-Aspartate, often seen as LOLA, is the stable salt of two natural non essential amino acids: L-Ornithine and L-Aspartic acid. These two amino acids play a crucial role in ammonia detoxification in the body.[22] Excess ammonia leads to premature fatigue, tissue damage, and in worst case scenarios, organ complications.

      During intense exercise, ammonia levels accumulate in the muscle leading to decreased performance. However, supplementing with LOLA prior to exercise has been noted to improve sprint performance and endurance capacity.[23,24]

  • Neuro-Amp/Cognitive Performance Blend

    • N-Acetyl L-Tyrosine (650mg)

      John Meadows

      Here’s the Mountain Dog himself, John Meadows, looking as ripped as ever.

      N-Acetyl L-Tyrosine (NALT) is an acetylated form of the amino acid L-Tyrosine, which makes it more water-soluble and supposedly more bioavailable. NALT is a popular focus booster used frequently in pre workouts to improve focus and cognition. This nootropic increases the production of two vital neurotransmitters, noradrenaline and dopamine which aside from improving focus and cognition, also lowers stress and anxiety.[25,26]

    • Caffeine Anhydrous (250mg)

      Providing the initial boost in Arc Reactor is a solid 250mg of caffeine. This is right in our wheelhouse of caffeine “sweet spots” for pre workouts, especially when paired with our next ingredient.

    • TeaCrine® (100mg)

      If you’ve “poo-pooed” TeaCrine® in the past, it’s most likely due to the fact that you’ve never had it dosed properly. All that changes here as Arc Reactor includes a massive 100mg of the long-lasting stimulant.

      TeaCrine® is a trademarked extract of theacrine that contains 98% concentrated theacrine. We’ve experimented with a few other products that have the full 100mg dose and honestly, we love it’s long-lasting energy boost!

      The great thing about theacrine is that it doesn’t come with the tolerance build up that caffeine does.[27] Basically, you can keep getting a significant increase in energy and mood, without having to continually up the dose (as you do with caffeine!

      Additionally, theacrine has been shown to reduce oxidative stress in the body when used for at least seven straight days[28], and increase dopamine levels in the brain, similar to caffeine.[29]

    • Theobromine (60mg)

      Granite Supplements Arc Reactor Mixed

      Here’s a shot of the watermelon flavor of Arc Reactor mixed up.

      Theobromine is yet another xanthine-like molecule similar to caffeine that’s extracted from the Theobroma Cacao plant. It’s structurally similar to caffeine, but doesn’t quite pack the punch that caffeine does, which is why we like it as a “backup” stimulant included in pre workouts.

      Theobromine does act like a mild CNS stimulant, but where it really shines is its long lasting energy and smooth come down from the stim rush.[30]

    • GS15-4™ Panax Ginseng (45mg)

      Lastly, we have an herb routinely used in Ancient Chinese medicine for its prevention and treatment of various diseases. Ginseng research notes improved mood, faster reaction time, and reduced fatigue.[31] Additional research surrounding ginseng notes reduced appetite and regulated blood sugar levels.[32,33]

Flavors Available

Arc Reactor has just landed, and John and Granite Supplements have delivered two flavors that are sure to fair well with the masses: Tangerine and Watermelon.

We know theacrine is notoriously hard to flavor and can affect the overall taste of the product, so it’ll be interesting to see how Arc Reactor taste. Companies are getting better and better with it, and the pros of Theacrine definitely outweigh the cons of its taste, but it’s still a fun thing to discover as formulators get better and better with it!
