Everything A Protein Should Be!



Undenatured protein = more protein!
To ensure a higher yield, the protein found in DIESEL is processed at 4° Celsius. Our advanced purification process helps ensure that the protein and active biofractions in the formula stay intact. These biofractions have their own unique biological properties to help support muscle repair and growth, digestive health, immunity, liver function and overall health.

Why is New Zealand Whey Isolate superior?
New Zealand is an island located in the southwestern Pacific Ocean. The moderate temperatures, fertile soil, excellent rainfall and yearly average of 2,000 hours of sunshine, provides ideal growing conditions for grass. This allows for cattle to flourish. In fact, New Zealand’s primary export is dairy.
Cattle graze throughout the year on grass, as nature intended, cycling through pastures across the land. On average, they spend 90% of their time roaming outside in pastures during the year.


Naturally sweetened with pure, natural Stevia extract
DIESEL is sweetened exclusively with Stevia, a natural sugar substitute. Best of all, you don’t need to give up taste for the ultimate in protein performance! DIESEL outperforms other proteins that still use artificial sweeteners like Sucralose or Ace-K (acesulfame potassium).
Using a protein that is sweetened exclusively with Stevia extract gives you that extra peace of mind. Those following a protein-rich keto diet often look for proteins that contain only stevia out of concern that artificial sweeteners may raise blood sugar levels.


DIESEL® Whey Protein Isolate InstantiZED for easy mixability
The whey protein isolate found in DIESEL also goes through an advanced agglomeration process to instantize the powder. The result? DIESEL mixes instantly in a shaker cup or a glass with a spoon. No clumps. No fuss. Just a smooth, creamy, deliciously refreshing protein shake.
Everything good, nothing bad
DIESEL stands further apart from other protein formulas due to its all-natural formula.
100% Authentic New Zealand Whey Isolate
What’s more, due to the advanced purification process employed by PERFECT Sports, almost all lactose is removed from our DIESEL New Zealand Whey Protein Isolate. Thus, making our DIESEL formula extremely easy to tolerate for those sensitive to lactose.

DIESEL NEW ZEALAND WHEY PROTEIN ISOLATE






















I am dismayed that when another distributor took over this product – they increased the price … but glad I can still get it.
Absolutely delicious – love the chocolate flavour. Mixes well in smoothies and in my shaker cup. Top quality product! thank you!
This is the best, high-quality isolate on the market right now! I’ve tried several flavors now but Milk Chocolate is my personal favorite and is very tasty. I think that DIESEL is worth every penny!
I’ve always had a difficult time finding a protein that doesn’t make me feel bloated or leave me needing to run to the washroom shortly after… until now! Since the formula is lactose-free, I can digest it without any issues. Plus, it tastes amazing. Prior to this, I used the Beachbody Vegan Recover for my post-workout protein. However, I’d much rather use a whey formula than a vegan one. I’m so glad I found this brand – it’s my new go-to!
We ordered exactly the same flavour and the same size container, which read 27 g of protein per 30 g serving. One container had a 24 g scoop and another container had a 33 g scoop. Same product, two different size scoops. I track all my grams of protein a day and this discrepancy is unacceptable. Both scoops were to provide 30g of whey protein powder. Neither did. How is that quality???
Thank you for reaching out to us with your question and being an avid support of PERFECT Sports.
To ensure accuracy, PERFECT Sports routinely performs density tests on each batch of DIESEL. When a batch is less dense, a larger scoop is used to provide the correct weight per serving. Conversely, if the batch is denser, a smaller scoop is included. This ensures that every serving provides the precise amount of protein listed on the label, regardless of the scoop’s physical size.
Rest assured the appropriately sized scoop is included for that lot # of protein.
