Is Your Protein a Milkshake or Supplement?

We grew tired of whey proteins that are full of flavourings, soy and additives made from lower quality dairy. Our ultra pure whey isolate is derived from Truly Grass Fed accredited cows using cold cross-flow microfiltration providing a more nutritious WPI which retains nearly 100% of its native undenatured structure.

Put yourself ahead of your competition. Reach your muscle & strength goals faster than the competition without the impact on your diet.

Exceptionally Clean Protein - It's Time for an Upgrade...

27g of undenatured grassfed whey protein isolate per 30g serving. Free from fillers, additives, soy & gluten.
 
Complete amino acid profile with unparalled digestability. Ultra low fat, carbs & lactose.

Mixing

GWI has incredible instantiation properties meaning that it readily mixes with water, milk and other liquids avoiding those annoying lumps that are all too common.

Flavour

Intentionally unflavoured to keep it as pure as possible to align with your nutritional goals. On its own, the flavour is completely clean and leaves zero aftertaste!

Bioavailability

GWI has a Protein Digestibility Corrected Amino Acid Score of 1.0/1.0 and is derived from grassfed dairy which has a greater quantity and variety of essential nutrients for muscle growth and recovery - get more from every scoop.

Digestion

Seize the most from your day without interruption. GWI is incredibly easy on the stomach, low-calorie and leaves no feelings of bloat unlike additive-packed whey protein shakes.

Leucine

Leucine is a key essential amino acid and BCAA in stimulating muscle protein synthesis (MPS). Leucine increases protein synthesis and activates the mTOR signalling pathway - acting like a molecular switch that turns on the manufacturing of muscle in the body. GWI is naturally high in leucine, containing 10g per 100g of powder or 3g per serving!

BCAA

GWI is a “complete” protein source, meaning it provides all the essential amino acids that cannot be synthesised by the body. BCAAs are of particular importance in supporting muscle recovery and muscle synthesis. GWI contains 22g of BCAAs per 100g of powder, providing a huge 5g more than 80% pure protein powders (the average).
