PRODUCT INFO

TRAIN HARDER. RECOVER FASTER. BUILD MORE MUSCLE. PERIOD.

No supplement in the world can take the place of basic hard work and consistency, but the right ones can certainly help.

Unfortunately, most so-called “muscle building supplements” out there fall far short of the mark.

More often than not they contain unproven ingredients that aren’t backed by real research and that are included at minimal dosages far too low to produce any significant effects.

Not only is it a waste of your hard-earned money, but you also miss out on the valuable performance and recovery benefits you could be getting with a proper supplementation approach.

With Cre-Elite, you’re getting a truly evidence-based formula you can trust using scientifically backed ingredients in their full clinical doses.

INGREDIENTS

REAL SCIENCE, REAL RESULTS:
COMPLETE CRE-ELITE™ INGREDIENT BREAKDOWN

CREATINE MONOHYDRATE

Creatine is the single most studied fitness supplement available with endless mounds of research supporting its training performance and body composition benefits.

By increasing intramuscular phosphocreatine stores, creatine supplementation allows your body to produce more ATP which is the key energy molecule during high intensity/short duration exercise. [1, 2, 3, 4, 5, 6, 7]

Creatine also requires additional water in order to be stored in the muscles, leading to an overall increase in fullness and definition.

Contrary to popular belief, this does not cause you to appear “soft” or “bloated”, since the water is stored inside of the muscle cell itself and not directly beneath the skin. [8, 9, 10, 11]

Additional proposed mechanisms of creatine supplementation include…

– Improved satellite cell signalling which may aid muscle repair and growth. [12]
– Increased levels of IGF-1 which may also play a role in optimizing muscle hypertrophy. [13, 14, 15]
– Reduced muscle protein breakdown. [16]
– Lowered levels of myostatin which is a hormone that directly inhibits muscle gain. [17]
– Enhanced cognitive function and prevention of certain neurological diseases. [18, 19, 20, 21, 22]

CRE-ELITE™ CONTAINS 5000MG OF CREATINE MONOHYDRATE PER SERVING.

Monohydrate is by far the most thoroughly studied form of creatine available and has a near perfect bio-availability in humans without any adverse effects. [23, 24, 25, 26, 27, 28]

Many supplement companies actively promote various types of “new and improved” creatine (such as creatine ethyl ester, buffered creatine, creatine hydrochloride and more), when in reality not a single one of these has ever been shown to be superior to monohydrate. [29, 30, 31]

L-CARNITINE L-TARTRATE

L-carnitine is an amino acid, while l-tartrate is a salt compound that can increase nutrient absorption.

When combined, l-carnitine l-tartrate (LCLT) has been shown to increase workout performance by enhancing blood flow and oxygen delivery to working muscles. [32, 33, 34]

In addition, LCLT also improves recovery after training by reducing muscle damage and soreness, allowing you to train harder and recuperate more efficiently in between sessions. [35, 36, 37, 38, 39, 40]

Another unique benefit of LCLT is its ability to optimize the hormonal status of muscle cells by increasing their androgen receptor content. This allows your existing levels of anabolic hormones (such as testosterone) to interact more effectively with the tissue. [41, 42]

Lastly, LCLT may improve insulin sensitivity. [43]

The research studied dose for LCLT is between 1-2 grams daily. [44]

CRE-ELITE™ CONTAINS 2000MG OF L-CARNITINE L-TARTRATE PER SERVING.

BETAINE ANHYDROUS

Betaine (otherwise known as trimethylglycine) is an amino acid isolated from beets which acts as an osmolyte, meaning it helps cells maintain optimal fluid balance.

Similar to creatine, higher intracellular levels of betaine increase muscle cell hydration and the ability to deal with external stressors.

Betaine supplementation has been shown in several studies to increase muscular strength and power output for better overall workout performance. [45, 46, 47]

In addition, it can improve muscular endurance and allow you to train more effectively during prolonged bouts of exercise due to its effects on mitigating levels of lactate. [48, 49, 50, 51]

The research supported dose for betaine is between 1.25 to 2.5 grams.

CRE-ELITE™ CONTAINS 2500MG OF BETAINE ANHYDROUS PER SERVING.

    Perfect for anyone

    Tastes great, no artificial or over sweetened taste. Perfect for drinking on its own or putting in some shakes. I do suggest giving more flavor options, but the tangerine flavor is good on its own.

    Lifting heavier than ever

    One scoop to liquid (I use diet tonic water) and you're good to go. I'm honestly not sure if it's psychosomatic but I'm lifting as heavy as I ever have at an always completely natural 63 yrs. old and 168 lbs.; 80 lbs. dumbbells for incline bench presses and recently moved UP to 65 lbs. dumbbells for seated shoulder presses and 680 lbs. for leg presses. Literally about to purchase again.

FREQUENTLY ASKED QUESTIONS

WHEN IS THE BEST TIME OF DAY TO CONSUME CRE-ELITE?

Cre-Elite is a “saturation supplement”, meaning the benefits are derived from consistent daily use.

It has no immediate effects on recovery or performance, so the specific time of day that you take it simply comes down to personal preference.

IS IT NECESSARY TO CYCLE ON AND OFF?

There is no specific advantage in terms of safety or effectiveness when it comes to cycling on and off of Cre-Elite.

Just consume one serving per day continuously for as long as you want to experience the benefits.

SHOULD I USE CRE-ELITE DURING A CUTTING PHASE?

Yes, Cre-Elite can be used whether your goal is to cut, bulk or recomposition. The ingredients in Cre-Elite will help you recover more effectively and maintain muscle mass/strength during a calorie deficit.

DOESN’T CREATINE MONOHYDRATE CAUSE BLOATING?

No, this is nothing more than a myth created by other supplement companies in order to charge a premium for their so-called “new and improved” versions of creatine.

Creatine monohydrate (just like all forms of creatine) does increase intramuscular hydration, but the additional water is stored inside of the muscle cell and not subcutaneously (directly beneath the skin).

If anything, creatine monohydrate will actually increase muscle definition and hardness.

CAN WOMEN USE CRE-ELITE?

Yes, both men and women can benefit equally from Cre-Elite.

I'M FOLLOWING AN INTERMITTENT FASTING DIET. WILL CRE-ELITE BREAK MY FAST?

While Cre-Elite is technically not “0 calorie” since it contains 4 grams of carbohydrates, the amount per serving is small enough to where your fasting period will not be negatively affected.

CRE-ELITE IS TOO SWEET/STRONG TASTING FOR ME. WHAT SHOULD I DO?

Everyone has different taste preferences, and we did everything possible to optimize the flavor profile while maintaining Cre-Elite’s 100% naturally sweetened/flavored status.

That said, if you do happen to find the formula a bit too sweet, you can simply add more water to dilute it.

ARE THERE ANY SIDE EFFECTS?

The ingredients in Cre-Elite have been shown to be both safe and effective when used within the recommended dosage, so there should not be any side effects in otherwise healthy individuals.

In the highly unlikely event that you experience an adverse reaction, discontinue use.

IS CRE-ELITE GLUTEN-FREE? VEGETARIAN FRIENDLY? VEGAN?

Yes, yes and yes!
