Creatine Is Every Athlete’s Cornerstone

It’s true— creatine has been the most trusted muscle-building supplement for years.

Creatine naturally helps to increase cell hydration in muscles— giving you that intense, satisfying workout every time.

However, not all creatines are created equally.

With its rise in popularity, many supplement companies have chosen to cut corners on their creatine formulas for more profits...

This has led to subpar-quality formulas with low doses of “after-thought” ingredients made in shady labs, all of which may lead to...

  • Zero results (causing you feel like your tolerance has gone up)
  • “Double scooping” because you’re not feeling the effects like you used to...
  • Muscle cramping— which should NEVER happen with a high quality, premium creatine formula
  • And even bloating, gas, and headaches...

Thankfully— it no longer has to be that way.

Crazy Nutrition has teamed-up with some of the hardest working trainers, athletes, and nutritionists from around the world...

To craft a real, premium creatine formula that delivers 5X more fuel than normal creatine formulas— all without loading, cycling, or causing a hydration imbalance.

5X The Fuel
For 5X The Output

Crazy Nutrition’s Ultimate CRN-5 is the only daily creatine formula that’s packed with 5 unique creatines with added electrolytes for optimal muscle hydration.

When combined together, our 5 creatines support increased ATP capacity1, which in turn may promote a higher output of muscle strength and energy than your standard creatine monohydrate.

Plus, with 5 creatines, you don’t have to worry about building a tolerance to one type of creatine, and causing you to supplement with more creatine to notice a difference...

Not with Ultimate CRN-5.

Just 1 scoop of Ultimate CRN-5 mixed with 8 to 12oz of cold water (or added to your favorite shake or fruit smoothie) is all it takes to support increased muscle strength and faster recovery.

Best part?

Unlike other creatines, Ultimate CRN-5 is formulated to be taken as a daily supplement, so you never have to worry about loading or cycling with a low quality creatine again.

Added Hydration To Keep
You Going Hard

We added premium-grade electrolytes— including the rich aquatic versions of magnesium and calcium— to help maintain muscle hydration, avoid muscle cramping, and push yourself harder while staying focused.

It’s time to ditch your grandad’s old creatine formula and try Crazy Nutrition’s Ultimate CRN-5 completely risk free.

If you do not experience a bigger, stronger performance, with a faster recovery time, and if Ultimate CRN-5 does nothing for you...

Then your hard-earned money will be refunded back into your bank account right away, every cent, with no questions asked.

Key Benefits Of Crazy Nutrition’s
Ultimate CRN-5 Creatine Formula 2.0

  • Intensifies Workouts

    With 5 clean, high-octane creatines + electrolytes, Ultimate CRN-5 supports a powerful protein synthesis with maximum hydration for a bigger output than what you’d find with a single creatine formula.

  • Maximizes Strength

    Crazy Nutrition’s Ultimate CRN-5 formula supports an increased ATP capacity, thus allowing your body to have more muscle fuel to push harder, have bigger bursts of energy, and break your personal best.

  • Increases Focus

    Did you know just a 2 to 3% drop in hydration can drop your attention and focus by a whopping 25%3?

    We added premium aquatic minerals to help support electrolyte levels within the body— which naturally maintains optimal hydration to keep your muscles fueled and your mind focused.

  • Preserves Muscle

    Afraid of losing muscle while cutting? The creatine formula in Ultimate CRN-5 helps preserve muscle gains while improving overall performance. According to one study, researchers discovered training combined with creatine supplementation helps “...improve maximal muscular strength and reduce muscle damage.”2

  • Supports Speedy Recovery

    A study published in the Journal of the International Society of Sports Nutrition revealed athletes who consumed creatine experienced greater muscle strength during recovery from exercise-induced muscle damage— including a 84% reduction in muscle soreness— compared to those that didn’t consume creatine.4

5 Creatines
+ Premium Electrolytes

Backed by science, trusted by professional athletes. Our one-of-a-kind Ultimate
CRN-5 formula contains 5 potent creatines + electrolytes to support the perfect
anabolic environment for more energy, gains, and muscle recovery.

  • Creatine Monohydrate

    Supports the natural production of phosphocreatine in your muscles, which in turn helps produce more muscle strength, boost energy, and help repair and recover.

  • Creatine Hydrochloride (HCL)

    Absorbed and utilized by your muscles faster than creatine monohydrate with zero bloating. Together, monohydrate & hydrochloride creatines help to keep you going harder for longer.

  • Creatine Ethyl Ester

    An athlete favorite, this unique form of creatine can go a long way at small doses and can penetrate your cells faster than other creatines for instant muscle strength and energy.

  • Tri-Creatine Malate

    Tri-creatine malate is completely water-soluble, which better supports ATP for improved muscle energy, endurance, and recovery, without the gassy side effects.

  • Creatine Citrate Pyruvate

    Creatine citrate pyruvate has been shown to improve cellular energy, which may boost weight loss efforts. One study showed 48% greater fat loss for individuals who supplemented with citrate pyruvate than those that didn’t supplement.5

  • Aquamin® Mg

    More bioavailable form of magnesium derived from a rich marine source, Aquamin® Mg helps support cellular functions, boost energy, and enhance muscle strength and repair.

  • Aquamin® Ag

    Made with arabic gum for improved digestion and absorption, Aquamin® Ag contains calcium from marine-rich sources, which has been shown to be more bioactive than regular calcium carbonate. Aquamin® Ag helps support bone health, strength & hydration.

  • Sodium

    We need sodium to keep our cells, nerves, and muscles functioning properly, and help maintain electrolyte balance for improved hydration.

  • Potassium

    Maintains energy, endurance, and hydration for the entire duration of your workout. Potassium also helps reduce feelings of fatigue and muscle soreness, while at the same time improve muscle recovery.
