Ultimate Fat Loss Stack

Finally! A weight loss solution designed to help balance your hormones, 

reduce stress, and burn fat faster & easier, 

without all the dangerous ingredients or nasty side effects.

Who’s it for?

If you're serious about transforming your body & finally feeling proud of the way you look - keep reading.
Look, we all know women lose weight more slowly than men. With guys, sometimes it's as simple as no longer drinking soda to lose 10lbs and to look completely different.
Why is it women have a much more difficult time than men losing weight?
Hormones! Women's hormones fluctuate constantly and are insanely more complex than men's.
Unfortunately this problem is only getting worse in our current society.
Our diets are loaded with unwanted hormones, we don't get enough sleep, and we live in a world of stress...
That's a recipe for disaster! No wonder we ALL have such a hard time losing weight these days.
Before we started Nutrithority we researched and tested hundreds of different fat loss formulas.
As you probably know, most of them didn't work...
The ones that did? They only worked for a short period of time before things came crashing down.
The problem? They all focused on the wrong things.
These 'fat burners' are like crack in a pill. Sure, they gave some energy... along with the jitters, anxiety, and nausea..
If you've ever tried these, you know the weight comes BACK ON even faster than you lost it... because it's not a real weight loss.
High stimulants will crank your energy up (burning calories) and blunt your appetite (causing you to eat less).... but it always comes back to bite you.
Afterward, energy plummets and hunger skyrockets causing the weight to pack back on and the cravings to be nearly uncontrollable.
That was NOT going to work for me or my clients. I knew there were better ways, so I decided it was up to me to make this happen.
After years of research, development, and testing - I finally had the solution.


Here's a bit of what you can expect with the Ultimate Fat Loss Stack:

  • A Perfectly Balanced System: Feel confident in what you're taking! Every ingredient was designed to support the others for the fastest results possible.
  • Clinically Dosed Ingredients: Spend your time focusing on important work, and let us focus on the details. We've done all the research and dosed everything at the most optimal levels.
  • Properly Support Your Body: Isothority is the purest, best tasting protein on the market. You'll be able to taste the difference with your first serving.
  • Increased Energy Levels: Get more accomplished with your day, without the crash! Our proprietary Flux system for energy ensures you'll feel great all day.
  • Enhanced Memory & Focus: Be more productive and get more things done with less time! Our Nootropic blend will help you focus and clear the fog.
  • Decreased Appetite: Stick to your diet with ease, eliminating hunger and cravings from your diet so you can keep yourself on track!
  • Hormonal Balance: Feel more at peace, relaxed, and lose weight in a way that is natural for your body.

The Ultimate Fat Loss Stack is a combination of multiple products:

  • Isothority - Ultra premium Whey Protein Isolate that goes through THREE phases of purification before it is ever used in Isothority. This allows it to digest incredibly easily and taste like you're cheating on your diet.
  • Amino Factor - Branched Chain Amino Acids that are so meticulously flavored, you'll think you're sitting on a tropical beach while you're sipping on them (even if you're at work).
  • Flux Elite Stack - The ONLY complete fat loss system that targets stress, and balances hormones to help weight loss naturally happen without the jitters, crash, or nausea associated with those 'other' fat loss products on the market.


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). 

Flux Elite Stack

What is the Flux Elite Stack?


Thermogenic Flux

  • All Day Clean Energy
  • Enhanced Focus and Productivity
  • Appetite Control and Mood Enhancement


  • Enhance Metabolic Capacity
  • Stimulate Thyroid Hormone Production
  • Support Fat Loss


  • Adapt to Stress
  • Regulate Cortisol
  • Suppress Excess Estrogen

Flux Elite Stack is a full 30 day supply of: Thermogenic Flux, Thermite, and Equilibrium. Each one of these products brings an incredibly unique aspect to weight loss.

Thermogenic Flux: 

Just say NO to the 'fat burners' that will leave you foggy brained, jittery, and unable to focus. Thermogenic Flux is a feel-good thermogenic designed to provide a clean all-day energy with no crash, increased focus and productivity while controlling your appetite and speeding up your metabolism.


While there's a lot of products that can control your appetite (calorie restriction) or increase your energy (calorie expenditure), there are very few products that can increase your metabolic capacity without an increase in energy. Thermite was designed to help enhance metabolic capacity, stimulate thyroid production, and support fat loss. You WON'T feel Thermite working other than being a little warmer throughout the day. This means you can increase your weight loss without increasing the shakiness of your hands.


Balance stress, and regulate your hormones. Our bodies handle a lot everyday, and all of the stress adds up. Whether it's less sleep, more coffee, stress at home, at work, or just the way we're made. Equilibrium helps your body adapt to stress with key ingredients like KSM-66 Ashwagandha. Regulating stress and the hormone cortisol aids in better recovery as well as fat loss. Cortisol is a hormone we want to be in the normal range, not elevated. Equilibrium also helps to regulate estradiol, a specific form of estrogen that shouldn't be out of balance in both men and women.

Thank you Terry!

Didn't work but no jitters

Unfortunately didn't do anything for me but also didn't give me jitters so that was good. I workout 5 days a week and do carb cycling with macros so was hoping this would help but no luck.

Sorry to hear you didn't see the results you were expecting Becky.

Christina B.
Love it!

I'm not sure if it's just the Equilibrium or all 3 combined, but my anxiety has all but vanished since about 2 days after I started taking this stack. My memory is also improving. I have also noticed my hormones have evened out and my urges for Sweets have become silent and that's super nice!
Definitely a huge fan of this!

Thank you Christina!

Mike K.
Tons of jitters

Equi and Thermite together give me great sleep at night, but Thermo Flux AF gives me accelerated heart rate and the jitters. Too much caffeine

Thanks for your feedback Mike! You may find that our original Thermogenic Flux is more your style. The ThermoFlux AF is the advanced formula, and definitely packs a stronger punch than the original Thermogenic Flux. More caffeine, more thermogenics - which can definitely mean more jitters and increased heart rate.
