NATURALLY HIGH-PROTEIN
Whey is a naturally high source of protein that contains all essential amino acids and is rich branch chain amino acids such as leucine. Whey is easily digested which allows the protein content to be absrobed rapidly by the body. This quick absorption helps reduce muscle breakdown and initiates the muscle repair processes immediately following exercise when consumed within 1-2 hours after exercise.
Whey protein is also naturally high in compounds that support immune function, helping athletes to perform every time.
COMPLETE AMINO ACID PROFILE
Contains all 9 essential amino acids
Learn more
COMPLETE AMINO ACID PROFILE
Whey protein is considered a complete protein because it contains all nine essential amino acids. It holds especially high amounts of the essential Branched Chain Amino Acids (BCAAs). Leucine is an especially important amino acid as it provides the signal to stimulate muscle protein synthesis

Tried cheaper protein shakes but they lack flavour and quality. SiS whey protein is worth the premium price

Tastes great, best of the available protein powder solutions from SiS. (In my opinion)
I look forward to drinking this stuff unlike the rego recovery.
Can’t wait to see the new whey based complete recovery.
I get powder on my wrist and arm every time I scoop due to bag opening size and short scoop length. I’ve started using my aero press scoop with the longer handle.
