Who Is This For?
Perfect Sports Diesel is for athletes who want a simple whey isolate — New Zealand grass-fed dairy, stevia-sweetened, 0g carbs and fat — and who care where their protein comes from, not just what's on the nutrition panel.
Who Is This NOT For?
- ✗ Budget-focused buyers — NZ grass-fed isolate carries a premium; a whey concentrate or blend will give you more servings for less
- ✗ Hard-bulk athletes who need calorie-dense shakes — at 100–110 cal per scoop, this is built for lean muscle, not a surplus
- ✗ Vegans or vegetarians — dairy-derived whey protein isolate
- ✗ Anyone with a milk allergy — Diesel is made from milk
- ✗ Under 18 — not intended for use by minors
What's In It?
Diesel is built on a single protein source: 100% New Zealand whey protein isolate from grass-fed, pasture-raised dairy. Perfect Sports says the cattle graze on pasture year-round and states no artificial growth hormones (rBST, rBGH). The isolate filtration removes most of the lactose, carbohydrates and fat, giving 26–27g of protein with 0g carbs and 0g sugar per scoop. Ingredients (Banana): New Zealand whey protein isolate, natural flavour, cellulose gum, stevia extract. Chocolate flavours add cocoa processed with alkali — check the label on your tub.
⚠️ Contains milk. May contain sesame and soy (Canadian label). Always read the full label before use. These statements have not been evaluated by Health Canada or the FDA for disease treatment or prevention.
