About SiS Whey Protein
SiS 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.
Why should I have SiS Whey Protein?
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.

About SiS Overnight Protein
SiS Overnight Protein (Chocolate) is made from high quality milk protein in a 50:50 blend with whey protein isolate for a great taste, providing a source of slowly digesting protein with a high amino acid profile to support lean muscle growth and maintenance as you sleep.
Milk protein is over 80% casein, which is a slowly absorbed protein and around 20% whey, which is rapidly absorbed. Whey protein stimulates the rate of muscle protein synthesis with its high leucine content. Each serving contains 26-27g of protein per serving and low levels of carbohydrate and fat.
Why should I have SiS Overnight Protein?
Sleep is one of the most important aspects of recovery and is often unappreciated by many athletes. Regularly feeding 20-25g of protein every 3-4 hours is the best way to support the growth and maintenance of lean muscle mass. Feeding during the night is impractical, so taking SiS Overnight Protein before bed allows quality sleep and quality protein delivery to maximise your training adaptations.
