Everything good, nothing bad

DIESEL® stands further apart from other protein formulas due to its all-natural formula. Our DIESEL formulas contain no artificial flavours; no artificial sweeteners (e.g. Sucralose, Aspartame, or Acesulfame Potassium); and no artificial colours/dyes.

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.

If that weren’t enough, our DIESEL protein powder contains no gluten and is peanut & nut-free!

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.

Full spectrum Amino Acid profile

When you consume protein, your body breaks it down into its individual components: amino acids. These amino acids can be classified as essential or non-essential. The essential amino acids need to be consumed in the diet whereas the non-essential amino acids can be made in the body (from other amino acids).

BCAAs from Whey Protein prevents muscle loss and support growth.

Of the essential amino acids, three are called branched-chain amino acids (BCAAs), which include: L-Leucine, L-Isoleucine and L-Valine. These unique amino acids bypass the liver and are primarily oxidized for energy in muscle tissue. BCAAs are generally consumed on their own to provide muscles with an energy source, while also helping to prevent muscle loss and support growth.

DIESEL Whey Protein Isolate provides 26g to 27g of amino acids (26g for chocolate flavours), 13g of naturally occurring essential amino acids (EAAs) and 7 g of BCAAs to help provide a favourable array of growth-promoting, muscle-sparing and energy-providing amino acids.

    Oh my word!! Absolutely my favourite fall protein powder. I used it in coffee and it makes for a healthier pumpkin spice latte.

  9. Allison (verified owner)

    LOVE LOVE LOVE this protein powder! Have not be disappointed with any of the flavours. My newest fav is the Candy Cane Ice Cream!

  10. Carla Romeo (verified owner)

    The limited edition Candy Cane Icecream flavour is absolutely delicious!! I made a smoothie with it and it tasted like a milkshake.
    I cannot wait to make some holiday treats with this one 🙂

  11. Adam Bowie (verified owner)

    I absolutely love this protein powder. I have a sensitive stomach but I have absolutely no issues with perfect sport products. I love the flavours, especially the seasonal candy cane and pumpkin spice. It’s so good in warmed up cashew or almond milk. It’s like a sweet hot treat!

  12. Brian Schooley

    Only protein I buy fell in love. I love that it is so simple with no artificial sweeteners just stevia 🙂

  13. Anmolpreet

    Excellent protein

  14. Dorsa GhorbaniFar (verified owner)

    This is the only protein powder I don’t have any digestive problems with! Very high quality and perfect taste! My favorite flavor is cookies and cream! I ordered the triple chocolate flavor as well and loved it, however I just wished it was a bit more chocolatey! I sometimes add more cocoa powder to get that rich flavor I want.

  15. RachelB

    I have had so many protein powders over the last 8 years. Can’t believe I only have begun to try out this product now. I have tried the salted caramel and the wafer crisp and love them both. Great macros, digestion, taste and blend ability! Highly recommend!

  16. Courtney (verified owner)

    The milk chocolate flavour is absolutely delicious. Sometimes I make myself a glass as a treat after dinner!
    Blends easily and not too sweet or fake tasting.

  17. David

    Best protein powder ever since i starting using them over 10yrs ago very very clean hope 10lb size soon…

  18. Tricia

    Strawberry is the best taste like real strawberry

  19. Tricia

    Taste just like a Reese peanut butter cup

  20. Mickey (verified owner)

    Great taste and was happy with those extra samples you slipped in. Thank you so much I’ll be ordering again for sure.

  21. Kaitlynn (verified owner)

    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!

  22. Sandy (verified owner)

    I love this protein powder! It is delicious for starters, but also great for a morning shake before a long day of cycling. I’m just not getting hungry during my cycles anymore,and have lots of energy to complete them.

  23. Siddharth

    Amazing protein and the best part about is the ingredients are so transparently specified and no bad stuff like aspartame or xantham gum . Super fast digesting and keeps my stomach light and taste is yumm. I’m sticking to this for my protein needs

  24. Jolene (verified owner)

    I love Diesel protein, I have digestive issues and I can tolerate this protein. I like it in oatmeal, yogurt and as a shake. All the flavours I have tried have been great! I can’t wait to try the new Easter egg limited edition!

  25. Jake

    Best diesel flavour to date! Highly recommend!

  26. OpenCageKitty

    Taste like Cadbury chocolate eggs! It’s great for not missing out on the holiday. You can stay dedicated to your goals and still participate.

  27. Peter

    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!
