007AU1I like the grass fed whey protein from diesel
Alternative_Ad_1440Diesel 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.
chipdanger168It'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
elvesandnutellaDIESEL CHOCOLATE OBSESSION
FinancialFinish3048You 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!
FunnyCorgi50Do the iso protein mix well for you? I got a 6lb tub and it clumps. I had diesel iso before and it smooth
