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.


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.

How does this differ from REGO?

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


When should I take this?

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 22g of protein per 30g serving.


Does whey protein contain creatine?

No, 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 protein shaker.

Good flavour, great for smoothies, and perfect for lean protein. Absolute bargain when it was on sale too!


I have tried several other brands and flavours but this is the one I find least sweet-tasting, smoothest, gentlest on the stomach and easiest to mix lump-free which is why I buy it all the time.

Ms Compton

Great product


Easy to mix and tastes ok. Above all an easy and convenient way of getting 25g of protein after working out.


Tastes great, easy to mix and good price.


Great product, tasty - I mix it with light coconut milk and a half banana and it tastes great


Great Product.

Simon Mallet

Doesn't mix as well as the Rego line, also lacks almost any flavour. Worth it for the money and yes, your not buying it becasue it tastes nice.. But it could still taste better than it does.

simon Jenkins

Product works but it tastes awful

Andrew Williams

A lovely tasting, easily mixed and nutritious protein supplement which is good on the stomach and really works well


Tastes good, easily digestible, very low calorific count and excellent value.


Mixes well with water or milk to give a consistent and tasty shake


Excellent product


tastes great. the powder is fiine and mixes quickly


Very thick, difficult to mix with milk as alternative to water. Nice taste


Ottimo gusto e provato sia come snack che come post allenamento breve. Molto bene.


Best flavor I mix it with oatmeal breakfast

Gellert Vinnai

I recommend the vanilla falvour to anyone as it can be perfectly mixed into any fruit smoothies. At least this is how I like to consume it.


A good way to get fuel in, before or after exercise
