Overview
Mixing a scoop into a shaker cup or a glass with a spoon is how the Diesel whey is meant to be used, since the powder is agglomerated to dissolve without clumps. It is a whey isolate from grass-fed New Zealand dairy.
Strong protein with zero carbohydrate and fat suits anyone tracking macros, and stevia replaces sugar. Servings per tub and scoop size are not in the listing, so the number of shakes per tub cannot be worked out from it.
Who it's for
Post-workout shakes made at the gym or at home are the setting, with a shaker bottle or a glass and spoon. Those with a true dairy allergy, or who need a plant-based powder, should look elsewhere.
Pros and cons

Performance notes
Isolate is filtered to remove most fat and lactose, which is why the macro figures are so low. The powder is agglomerated, meaning grains are clustered so water wets them evenly and they dissolve fast. Cold processing is said to protect the protein fractions, though the listing gives no test data.
