What is the difference between this and SiS Whey Protein?

SiS Advanced Isolate+ has one of the highest known digestion rates and a higher BCAA content. The addition of 9g of BCAA's and 5g leucine help stimulate and support the growth of lean muscle mass. SiS Advanced Isolate+ is more purified, providing a higher protein content (31g) and lower levels of carbohydrate and fat.


When should I have this versus SiS Whey Protein and SiS REGO Rapid Recovery?

SiS Advanced Isolate+ can be consumed with or between meals to hit the recommended protein intake of 20-15g every 3-4 hours. Consume immediately post exercise, particularly after strength and conditioning sessions. This is ideal for individuals looking for minimal carbohydrate and fat intake, while maintaining and building lean muscle mass.


Why is it more expensive than SiS Whey Protein?

Whey protein isolate is digested and absorbed quicker than whey concentrate. SiS Advanced Isolate+ is a purified version of whey concentrate with additional leucine, which increases protein content with minimal carbohydrate and fat.

I wasnt super happy with the flavor, but definitely will try again a different one

Gareth Smyth

Tastes great and really easy to mix and drink - plus its 31g of protein per serving - definitely recommend.


Best isolate whey protein with high content protein that I have ever used for building lean muscles. I'm normally lactose intolerant and this is perfect for me. G

Miquel Tomas

Great product if looking for high protein powder.


You need to weigh the doses and not rely on the scoop measure as you will never get the advertised number of doses out of it and will be wasting powder as you can only absorb so much in one serving...


Tastes really bad cant drink without throwing it back up

Dennis Nelder

Great deal and a new flavour to try...
