Mr Fusion

What is Mr. Fusion?


Mr Fusion is the ultimate coalescence of pump and energy.

  • Unrivaled Pumps and Blood Flow
  • Sustained Clean Energy & Focus*
  • Power and Strength Intensifier*

Mr. Fusion provides an incredibly clean energy while maximizing pump and endurance. You'll be more focused, energized, and perform better through your workout. The amount of caffeine and stimulants is much more mild than other pre-workouts, so you shouldn't feel a 'jittery' or anxious.

  • Improved Blood Flow 
  • Increased Nitric Oxide Production
  • Improved Blood flow the muscle
  • Decreased Muscular fatigue
  • Increased endurance and muscular performance 
  • Steady No- Crash Performance 
Who is it for?

Anyone needing to improve energy and performance from their workout but doesn't want something that makes them feel jittery. This is an ideal product when looking to maximize muscular performance, increase strength, and endurance.

What will I notice?

If you've taken pre-workout before, you will notice a bit of the tingling feeling caused from beta alanine. This is normal and likely the first thing you'll notice. You will also notice increased energy and alertness before much else.

During your workout you'll notice an increased pump (blood flow) in the muscle you're training. Set after set you'll notice you can keep pushing further than you would normally and aren't fatiguing as quickly. You'll be able to workout harder and longer than normal with less overall fatigue.


What is Isothority?

Isothority is a cross-flow cold-microfiltered whey protein isolate. Sounds fancy, right? Let's break it down: Isolate is the purest form of Whey Protein available. You get less filler, carbs, lactose, etc. This means it also digests much more easily without stomach issues.

The method by which the protein is extracted is much more precise. Rather than using extreme heat, acid washes, and other harmful processes, we utilize a filtration system to isolate the protein.

This leaves an incredibly clean protein that is easy to flavor, has a great texture, and digests extremely well. There truly is not another protein that is this pure, and tastes this good.

Who is it for?

Everyone. If you are exercising, restricting your calories, or cleaning up your diet - you'll benefit from Isothority. Isothority is especially important after your workout as it will help you recover faster, be less sore, and boost your metabolism.

How do I use it?

The most important time is after your workout - 1 scoop mixed with 6oz of water (or milk) will do it for most everyone. It can also be utilized at any other time you would need a protein source; as part of a meal, as a milk shake, or just to increase total protein intake for the day.

What will I notice?

This is a tricky question. Here's another way to look at it: What would you notice from eating a chicken breast, or egg whites? In general, you will be less sore after your workouts. Your body will adapt and gain strength and endurance much more easily. You'll also boost your metabolism and stave off hunger more easily when taking a quality protein source in.

Amino Factor

What is Amino Factor?

Amino Factor is a simple product. It only contains three ingredients:

  • L-Leucine
  • L-Isoleucine
  • L-Valine

Those three amino acids make up the Branched-Chain Amino Acids or BCAA's. 

Basically, these are the most important amino acids you could take in to help protect and rebuild muscle tissue around workouts.

Amino Factor is a 2:1:1 Instantized BCAA product. That specific ratio is one that has been clinically proven to increase muscle protein synthesis, speed up recovery, reduce DOMS (delayed onset muscle soreness), and reduce muscle catabolism (waste).

Simply the best.

I've tried the rest - Mr. Fusion is the best. Best quality; best flavor; best customer service. No need to look anywhere else.

Thank you Justin!

Mr. Fusion

Flavor is great, and the supplement does a great job for pre workout without over stimulation and no crashes later. Small focus increase, seems to help with pumps, and just enough caffeine.

Thanks Austin!

Thank you Renee!!!

Heather P.

This is by far my favorite pre-workout. Great flavor (perfect blend of grape & lime), no after taste, and not too sweet. Gives a great boost for your workout without feeling jittery. Will definitely purchase again.

Thank you Heather!!

Great products

The Fusion Starter was the perfect introduction to the Nutrithority products. All flavors were delicious, especially the Protein Powder Caramel Coconut Cookie and Mr Fusion Pineapple Punch. Caramel Apple Amino Factor had a nice taste but much more apple flavor than caramel flavor. I received a handful of samples with my order, all of which were pleasant tasting. I will likely be switching from Mr Fusion to the 1.21GW preworkout. Fusion works well but I could use a little more bang and the sample provided helped me see the 1/2 serving size of the 1.21 is perfect for a little more energy and pump. Have definitely noticed less muscle fatigue and quicker recovery using these products. Will buy again!

Thank you Kristin!! Glad you liked it!

Works great and tastes great!

I have been using Mr Fusion for probably 6 to 8 months now and do like it. Works good for me (At 75 years old), and the raspberry rage tastes very good.

Thank you Jim! 75 is awesome, keep after it!!
