Diesel whey isolate, not the whey protein. By far the best flavors, specifically milk chocolate.
Perfect Diesel whey isolates have some of the best flavors and are pretty clean.
It’s slightly more expensive but I switched to Diesel from Perfect Sports. Leanfit and ON are 24 grams of protein per 32 or 33 gram serving, which is only 72-75%. Diesel is 27 per 30, which is 90%. It’s a whey isolate which I digest much better and I believe the lower amount of fillers also helps that. I wait for a sale at Healthy Planet as it usually drops to $90 for a 5lb tub. Best tasting protein and highest macros in the market in my opinion.
Unfortunately not. Walmart sells a “Diesel” but it’s their 24gram version which is a rebrand of their “Perfect” option sold in health food stores. Nothing wrong with that version but it’s similar to Leanfit and ON but even lower at 69% protein per serving
The only thing that pushes me away from the vita plus powder is the sucralose. I prefer sugar free sweetened with stevia only. Perfect Sports Diesel is grass feed NZ whey isolate is no sucralose and made in Canada.
I agree it's one of the best ones out there. Just wish it was a bit cheaper. Walmart also sometimes has the 2lb tubs on sale for 29.99 and I think it was the isolate one
It's okay. But if you're going to spend $90 you may as well wait for a perfect sports sale to get their isolate on sale for $120. It's much cleaner and tastes better
The Perfect Sports Diesel milk chocolate flavour tastes exactly like chocolate milk in my opinion. It mixes very good as well.
Do the iso protein mix well for you? I got a 6lb tub and it clumps. I had diesel iso before and it smooth
I use to be a diesel guy, but their prices have gotten silly, especially on isolate, the do have one that has FUEL written on it, I’ve had it in the vanilla ice cream flavour, it’s fine, it’s not quite as clean but mixes and digests fine. I think 4.4 pounds is usually 59.99$ which is a decent price when it comes to protein these days
I’ve bought that stuff too, don’t like the flavours at all. The vanilla ice cream one is fine, I just find those, they sell them at Lawton’s too, they taste like chemical.
Costco haha sorry. I originally bought Diesel brand on sale at Walmart. 2lbs for $30.
I used to buy Diesel but it's price has sky rocketed. I use Leanfit from Costco now. It mixes well. Doesn't taste as good. I bought a couple Good Proteins and it's decent. I don't like artificial sweeteners so I always look for natural sweetener.
Best protein powder is the Diesel brand, no artificial flavours etc.
