Rule 1 R1 Protein

What is Rule 1 R1 Protein?

What matters most after a workout?

It’s all about speed.

You know you need protein after a workout.

Did you know that you need a FAST digesting protein after a workout?

In order to maximize your results, your muscles need an immediate source of amino acids. This is when your body is primed to absorb the greatest number of nutrients for recovery. If you’re eating a steak or chugging casein, you’re doing it wrong.

When you want the fastest digesting protein that also happens to be of the highest quality, you need Rule 1 R1 Protein.

R1 Protein from Rule 1 is a barebones formula that includes ONLY what your muscles need for maximum results. You’ll get protein… and that’s it. It is free from sugar, fat, gluten, gums, creamers, and nitrogen spiking. There are no secrets with this protein, just elite quality and your fitness success.

Give your muscles 25 grams of the most elite isolate and hydrolysate blend on the market with R1 Protein from Rule 1.

What are the benefits of usingRule 1 R1 Protein?

While low grade protein supplements are packed with artificial fillers, colouring, and fillers, R1 Protein from Rule 1 has only one thing to offer: high quality protein. In every serving of R1 Protein from Rule 1, you’ll get the following:

Whey Protein Isolate

This fast digesting protein is able to provide your muscles with an immediate shot of amino acids. As a result, these amino acids may be able to trigger a higher level of protein synthesis to promote muscle gain and recovery.

Whey ProteinHydrolysate

This form of protein is already broken down, ensuring immediate absorption. The amino acids that are delivered to your muscles may be able to promote post-workout recovery while enhancing lean muscle tissue. (1-6)

Who should be using Rule 1 R1 Protein?

Who says you can’t have elite quality and a high dose of protein at a reasonable price?

R1 Protein from Rule 1 is the ideal choice for anyone who wants to pump their muscle tissue full of amino acids right after a workout. When taken as directed, R1 Protein from Rule 1 may be able to help you achieve your muscle building and fat loss goals.

No turning back

By Mark reviewed on 26/11/2021

Noticed the improvement in training fairly quickly, step change in intensity and absorption process. Less protein than ON but feels as though bioavailability may be higher. No turning back.

Simply great

I have the cafe Mocha flavour and it's great. Protein itself does not cause any bloating and recovery is quicker as compared to the days without this protein.

Great tasting; easy on the stomach

By Kosta reviewed on 6/02/2021

Verified buyerA verified buyer is someone who has purchased this product from Amino Z

No point ‘buzzing’ if your overstimulated gut promotes your adrenals to pump cortisol production at all hours. In this sense this product is ideal. Performs well but easy on the stomach. Just don’t forget the dextrose to super charge that amino acid muscle injection ;)
