The Science

Behind IM-21

Maximum strength, health and vitality doesn't come from what you eat, but what your muscles absorb [1]. So every aspect of IM-21 is engineered to maximize the absorption of the things that make you thrive.

Protease, Fructose, and Fulvic Acids improve the absorption of essential amino acids, vitamins and nutrients from the food you eat. Creatine, HMB, Vitamin D3, and Glycine help your muscles to use this fuel more effectively to supercharge your strength and fitness.

This combination is unlike anything else you've ever seen. And it's delivered twice a day, instead of only once, to make sure none of it goes to waste.


How It Works

The Unique Muscle Building, Fat-Torching Formula You Can't Find ANYWHERE Else.


Creatine Burn

Possibly the most widely studied muscle building compound on earth. In the right proportion and formulation to explode your results for bigger muscles (and less fat) FASTER.


HMB+D3 Burn

Scientifically proven to increase strength and muscle mass — even without exercise — formulated to supercharge your results.


Build Valerian Root

Improved recovery = better results. Our bodies wear down every day, but you can rebuild yours stronger in your sleep IF your sleep is optimized for repair.


Build Gaba

Promotes faster sleep onset without sedation. Sleep longer and deeper in less time while giving your body the fuel it needs to BUILD.

So much better than anything else I've tried.

I've tried tons of different supplements and products ove the years. Protein, creatine, expensive vitamins, everything. This is just better. It's hard to describe just how much better I feel. It's like being back in my prime.

I've been trying to lose weight for years. When I finally shed some of the fat, my muscle disappeared too. I couldn't stand feeling weak all the time. Now, I feel strong and dominant. My strength, energy and drive are coming back and I LOVE it. Thanks Mike!.

Better Sleep and More Energy

IM-21 makes me feel incredible. I haven't felt like this in over a decade at least. (I'm 47). Burn gives me a quick boost in the morning and makes me feel like I can crush anything the day throws at me. Build is like an "off switch" for my brain. I've never slept this good!

Frequently Asked Questions

IM-21 is formulated in a GMP certified facility under completely sterile conditions. GMP Certification means that the FDA recognizes the lab for following the highest possible standard for accuracy, safety and purity. Every ingredient in IM-21 Burn and Build is individually tested for impurities before it is even accepted into the Lab

They have achieved the highest possible level of manufacturing excellence recognized in the United States.

We believe that IM-21 is the most advanced forulation ever created, using the perfect balance of the highest quality natural ingredients.

Creatine, HMB, Vitamin D3, B-Complex Vitamins, Gaba, Valerian, Cordyceps Sinensis and Papain essential and non-essential amino acids and more to support total wellness at the cellular level.

Wth think it creates a difference you can feel. And we invite you to try it for yourself.

Your daily serving of Burn contains 75 milligrams of caffeine. That's less than you'd find in a typical cup of American coffee, or about the same as two 12 ounce cans of Cola. Many energy drink and pre-workout products contain 3-5 times this amount.

We don’t recommend that anyone sensitive to caffeine consume Burn less than 12 hours before your intended bedtime, as sleep quality is equally important for the success of the IM-21 protocol.

Unfortunately, there is currently no caffeine-free formulation of IM-21 Burn, and Build is not currently for sale independently.

If you are exceptionally sensitive to caffeine and cannot tolerate consumption of 75 milligrams per day, we would recommend avoiding IM-21.

Build, IM-21's night time sleep formula contains 3mg of melatonin in order to maximize it’s sleep promoting properties. Melatonin is responsible for promoting feelings of relaxation in your body and signaling when it’s time to go to sleep.

Build, however, is not only a melatonin product. Many melatonin sleep products contain 20MG or more melatonin per dose. Our philosophy is to use minimum effective doses of every ingredient. So Build’s synergistic blend contains only 3MG of melatonin.

Combined with Build’s other sleep promoting ingredients, like GABA, Valerian, Cordyceps, and L-tryptophan, the melatonin in Build can still result in a deep, restful, restorative sleep without requiring oversized doses of any of the ingredients

3MG may be a small enough dose even for those with a sensitivity. However, only you can decide your own personal tolerance. If you are avoiding melatonin completely, unfortunately Build is not the product for you.

The ingredients in IM-21 are backed by decades of clinical research, including placebo controlled double-blind studies. They were selected and formulated to maximize their synergistic effects with each other and create the ultimate muscle building formula.

While individual results will vary and there are no "typical" results, we have had excellent feedback from the people who have tried IM-21.

And Ultimately, Mike’s own story ultimately speaks for itself.

While we believe that IM-21 is the Ultimate Anabolic Formula, we understand that nothing is right for everyone.

In the event you decide that IM-21 isn't right for you, for ANY reason at all, we invite you to contact us at your earliest convenience to claim a full refund.

Mix one packet of the IM-21 Burn in 12 ounces of water for a sweeter taste or 16 ounces if you like it more diluted. You will drink this in the morning to start your burn for the day.

Mix one packet of the IM-21 Build in 12 ounces of milk or milk substitute for a sweeter taste or 16 ounces if you like it more diluted. You will drink this about 30 minutes before bed to start your Build and get a restful night sleep.

Between Burn and Build, there are 21 active ingredients in the IM-21 product. The only other ingredients are the flavors and magnesium stearate, a preservative and anti-caking agent.

Coincidentally, Mike was 21 years old when he unified all 3 heavyweight titles in 1987. (He was 20 when he won his first heavyweight title, becoming the youngest heavyweight boxing champion in history, before or since.)

Literally anything you like. They will dissolve in basically any water based liquid. Creatine specifically is best absorbed when consumed with some sugar. (This is why we add 3 grams of all-natural fructose [fruit sugar] to every dose of Burn and Build.)

So, if you do wish to mix either product with something like fruit juice or even tea, go right ahead. Just be sure to keep in mind that extra calories, even from fruit juice do add up over time.

Lastly, Burn already contains roughly 75MG of caffeine (a little less than a standard cup of coffee) so you may not want to mix it with any additional caffeine depending on your personal tolerance.

Likewise, Build is intended to help you get a great night's rest, so caffeine would NOT be a good inclusion.

HMB, D3, and Creatine were specifically studied for their ability induce muscle protein synthesis even in people who were not exercising.

They will work to help boost your strength and muscle mass no matter your current daily routine.But, and this should go without saying, they obviously work even better when paired with a sensible exercise plan. You don't need to be training for a triathalon or a heavyweight fight, but you should be engaging in some light, daily exercise for your health ANYWAY.

As for weight loss, there is no substance known to man that can cause your body to lose weight even in a massive caloric surplus.

This product is intended to help your body digest food more efficiently and fuel your muscles with the amino acids they need. This will naturally help promote weight loss even without a significant change to your diet or exercise routine.

But if you wash down your daily glass of burn with a donut, you may find it hard to keep the weight off.

Burn is flavored with all natural citrus flavoring. Think “TangTM” or orange juice, but a lot more subtle.

Build is flavored with chocolate fudge flavor. But because it has no artificial colors or dyes, it’s not dark brown like you might expect.

If you drink it hot, several people have described the flavor as “white chocolate mocha”.
