Fact Checked

Creatine is the world’s most researched muscle-building supplement.

On top of that, all of the studies agree to some extent that it actually works.

With that said, there are thousands of bad underdosed creatine products out there.

Ultimate CRN-5 by Crazy Nutrition has been one of the most popular creatine supplements on the market for some time now.

Who is it for?

It’s for men and women that want to gain or maintain strength and recover faster from workouts.

It’s as simple as that.

CRN-5 is so versatile that it doesn’t matter if you’re bulking or cutting if you’re a bodybuilder or an endurance athlete.

It will help you get better results from your efforts.

This means that if you’re in the gym lifting weights, you will build more muscle from the same effort.

Gain more strength and even be able to lose fat faster.

Who is it NOT for?

Listen, yes it’s in my opinion the best creatine supplement on the market right now.

However, it’s “just” a natural supplement.

This is NOT a steroid or anything that boosts your muscle-building hormones.

It’s not a “magic pill”. So if you’re expecting to look like daddy cbum after a couple of weeks on this stuff then GTFO, it’s not for you.

You need to be patient to see massive results.

Take it consistently for a month or two and notice your muscle gains skyrocket.

How does it work?

Ultimate CRN-5 by Crazy Nutrition fuels up your muscle cells after a heavy workout.

It also gives your plenty of electrolytes for boosted focus and muscle hydration.

It also supports powerful protein synthesis for maximum results.

This means that it helps you build muscle and strength at a more rapid rate.

My thoughts

Okay, so, usually in my time as a bodybuilder I’ve just gone and bought a large bag of the cheapest pure Creatine Monohydrate.

And to be fair, you can still do that and get great results.

However, the combination of 5 premium creatine types (including Monohydrate) in CRN-5 is simply on the next level.

I’ve never felt a creatine supplement kick in as fast as this.

My gains are through the roof.

Plus, I’m sick and tired of taking unflavored creatine and I LOVE this orange and mango flavor that CRN-5 has.
