I like the grass fed whey protein from diesel
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
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
DIESEL CHOCOLATE OBSESSION
You should try diesel whey protein specifically diesel whey protein isolate the vanilla flavor is amazing it’s Madagascar vanilla and is the best vanilla protein powder I’ve ever had, the protein quality is excellence especially for the price and I like to get it off of muscle and strength supplements for the best price. Best of luck!
