Crazy Nutrition Supplements

Crazy Nutrition offers three flagship supplements, including a protein powder, a pre-workout, and a creatine supplement:

  • 100% Tri-Protein (a protein powder)
  • Ultimate CRN-5 (a creatine supplement)
  • Intensive Pre-Train (a pre-workout formula)

We’ll discuss each supplement and how it works below.

100% Tri-Protein


100% Tri-Protein is a protein powder designed to increase gains, promote muscle growth, boost energy, and satisfy hunger. Each serving contains 21g of protein from 6 different sources. The six types of protein work in 3 different stages, building muscle at varying times and in different ways.

Most protein powders contain just one type of protein. You might take a whey isolate protein powder, for example, for rapid muscle growth after a workout. However, by taking multiple sources of protein – like casein and whey protein – at the same time, you can boost results, increase protein absorption, and give your body different amino acids required for bodybuilding.

Crazy Nutrition’s 100% Tri-Protein contains whey protein isolate, whey protein concentrate, micellar casein, milk protein concentrate, calcium caseinate, and whey protein hydrolysate. Your body absorbs these six protein types in different ways. It takes your body longer to break down and absorb casein protein than whey protein, for example.

By taking six types of protein in one supplement, you can ease bloating, maximize absorption, and give your body all of the protein it needs to support muscle growth.

100% Tri-Protein is available in a chocolate flavor. Each serving (1 scoop / 30g per scoop) contains 97 calories, 0.8g of fat, 1g of carb, and 21g of fiber. Instead of overloading the formula with sugar (there’s just 0.9g of sugar per scoop), 100% Tri-Protein contains cocoa powder and sucralose for flavor and sweetness.

  • 100% Tri-Protein Price: $44.99

Ultimate CRN-5


Ultimate CRN-5 is a creatine supplement with five sources of creatine. By taking the supplement daily, you can give your body robust muscle growth, increased blood flow, and enhanced pumps.

Ultimate CRN-5 also adds electrolytes for better energy and hydration. You need to drink more water when taking creatine, and the electrolytes in CRN-5 ensure you stay hydrated even when consuming large amounts of water.

By taking Ultimate CRN-5 daily, you can purportedly boost energy, support lean muscle mass, and maintain hydration – all while giving your muscles more strength to push out those last reps.

While most creatine supplements contain just one type of creatine, Ultimate CRN-5 contains creatine monohydrate, creatine hydrochloride, creatine ethyl ester, creatine pyruvate, and tri-creatine malate. By giving your body different types of creatine from various sources, you can maximize absorption and boost the usefulness of creatine, helping you maximize muscle growth.

  • Ultimate CRN-5 Price: $29.99

Intensive Pre-Train


Intensive Pre-Train from Crazy Nutrition is a pre-workout supplement available in blue raspberry flavor. The supplement contains 19 proven pre-workout ingredients to help boost energy, focus, and motivation.

According to Crazy Nutrition, Intensive Pre-Train can provide powerful benefits without jitters, stomach cramps, or digestive issues. While other pre-workout supplements lead to unpleasant side effects, Crazy Nutrition emphasizes the natural energy boost of Intensive Pre-Train.

By taking Intensive Pre-Train before a workout, you can purportedly:

  • Enjoy incredible energy without crashing
  • Avoid brain fog and boost focus
  • Feel muscles surge with power by increasing pump
  • Regain confidence at the gym and improve drive and motivation

Each serving (1 scoop / 25g per scoop) of Intensive Pre-Train contains 7g of citrulline malate, 2.5g of beta-alanine, 1.8g of betaine anhydrous, and substantial dosages of other amino acids, vitamins, and minerals. There’s also a significant dose (200mg) of caffeine anhydrous. Plus, Intensive Pre-Train contains Bioperine (black pepper extract) for absorption, ashwagandha (as an adaptogen to help with physical and mental stress), and En-Xtra (an energy-boosting blend designed to minimize jitters).

Overall, Crazy Nutrition has designed Intensive Pre-Train to provide all of the benefits of pre-workout supplements with no downsides.

  • Intensive Pre-Train Price: $39.99


Crazy Nutrition Features

You have plenty of choices for pre-workout supplements, creatine formulas, and protein powders. What makes Crazy Nutrition unique? Why buy supplements from Crazy Nutrition?

Here are some of the advantages offered by Crazy Nutrition and its lineup of supplements:

Strong Dosages

Crazy Nutrition has substantial doses of the most active ingredients. Because the company lists its dosages upfront, it’s easy to compare the strength of Crazy Nutrition supplements to the strength of other formulas. Crazy Nutrition’s Pre-Train, for example, contains 7g of citrulline malate and 200mg of caffeine.

Transparent Ingredients

Many supplement companies hide ingredients and dosages behind proprietary formulas, making it impossible to see what’s inside each serving. Crazy Nutrition takes a different approach, disclosing the dose and name of each ingredient in every supplement. The company also publishes its ingredient labels upfront, making it easy to compare the supplements to competing formulas.

Multiple Sources of Protein, Creatine, and Other Active Ingredients

Most protein and creatine supplements have just one source of protein and creatine. Crazy Nutrition’s flagship supplements, however, contain multiple sources of each. Instead of getting just one type of creatine, for example, you get five types. Instead of getting just one kind of protein, you get six types of protein that work across three stages.

Better Bioavailability and Absorption

Crazy Nutrition has worked hard to boost the absorption of its formulas. The company uses multiple types of protein and creatine to maximize your body’s ability to absorb the ingredients, for example. They also use ingredients like black pepper extract that have been shown to boost absorption. Some supplement companies take the time to add these complementary ingredients to their formulas, while others do not.

60-Day Money-back Guarantee

You can try any Crazy Nutrition supplement for 60 days. If you don’t like it, you can request a complete refund on your purchase. If you don’t feel a difference in your performance, then you can get your money back.
