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.

Great product, easy to use and shake up, tastes really chocolatey without being sweet. Would like a 30g scoop rather than the 15g, but that’s just being picky!

Low sugar whey protein with bcaa, even better mixed with milk!

Alan Jackson

been using Whey Protein on my rest days for several years now and like all the flavours and the benefits of using this product

Everest29

On my 2nd tub now, pleased with it and the service from SIS.

Nick Esser

Pretty good protein with relatively low calorie count. Good for post exercise or to bolster your nutrition. SIS were limited in their ingredients online but if you know what you’re looking for.....

Nick Maingay

Great product. Tasty and easy to use.

Rory Burford

My go-to protein powder. I genuinely enjoy the taste - especially if added to milk and blended (i.e a delicious protein-packed milkshake). I can't justify getting it at its normal price, but I would strongly recommend stocking up whilst it's on offer.

Diego Civitella

Prodotto ottimo, di facile solubilità, buon sapore ma soprattutto facilmente digeribile.

andrea

Very good taste. It would be great to have it also in bag, to reduce scraps

Elise Kamanda

Love this product works a treat

Guest

Proteine di ottima qualità!!! Nessun problema digestivo è buonissima solubilità!
