Product Information

Whey Protein contains a blend of high quality whey protein isolate and concentrate, providing a source of rapidly digesting protein.

A high amino acid profile which supports lean muscle growth and maintenance, with at least 5g of BCAAs per serving, including 2.4-2.5g of leucine which increases the rate of muscle protein synthesis. Each serving contains 22-23g of protein, depending on the flavour you choose.

Key Features

  • • Contributes to the maintenance and growth of lean muscle mass
  • • Fueling gold medal winners since 1992
  • • 22-23 grams of protein
  • • Contents: 33 servings with scoop included.

Product Uses
Recommended Usage

Our Whey Protein can be used with or between meals to support lean muscle mass or immediately after strength and conditioning sessions, with the goal of ingesting 20-25g of protein every 3-4 hours.

Directions for Use

Add 30g of Whey Protein Powder using the scoop provided (each scoop holds 10g, so 30g is 3 scoops) to 250ml of water in a shaker. Shake well ensuring the lid is firmly closed.

Benefits

SiS Whey Protein is a great tasting, convenient way to increase daily protein intake. It is recommended that 1.4-1.6 grams of protein per kg of body weight is consumed each day in order to promote lean muscle mass. For a 75kg male who trains regularly that would equate to 120g of protein per day.

FAQ's

How does this differ from REGO?

SiS Whey Protein is lower in carbohydrate than REGO, promoting muscle rebuild and reduction in muscle soreness post exercise.

 

When should I take this?

SiS Whey Protein can be used with or between meals to support lean muscle mass or immediately after strength and conditioning sessions, with the goal of ingesting 20-25g of protein every 3-4 hours.

 

Do I mix with water or milk?

Although milk is high in protein, it's also high in carbohydrate and is made up of 80% casein, which is slow digesting. Mix with water to increase absorption rates, which is ideal for use post exercise.

 

How much protein is there per serving?

There is 23g of protein per 30g serving.

 

Does whey protein contain creatine?

No, SiS whey protein does not contain added creatine.

 

How many scoops with the included scoop per serving?

Add 3 scoops (30g) to 250ml of water in an SiS protein shaker.
