AdNeat9717Canadian Protein chocolate hazelnut + add peanut butter and a banana
h3xx_rdI agree with you. They have multiple options at different price points depending on what you’re looking for. Personally, I really like the Whey Protein Isolate Natural Chocolate Milkshake (Stevia version). It’s the best tasting Chocolate protein shake I’ve had. Their strawberry and vanilla flavors aren’t bad either. Mixes really well and I’ve had no issues with digestion.
hide-my-email-Canadian Protein! I am currently loving their Cappucino Whey protein and it is such a treat.
IntoxxWhey isolate Cappuccino flavour was really good. I don’t really like the chocolate hazelnut I got on sale

LeatherGood6148The banana creampie (I know, I know) flavour from Canadian protein. I bought a 20kg of it of it I liked it so much. It came shipped on a small pallet, it was quite funny. ~~I believe both the size and the flavour has been discontinued.~~ They still have it. I won't need more for several years though.
I felt like a barn animal lmao. When I told the front desk concierge what it was they laughed their ass off at me. It's been 2 years. I still have half of it. Makes amazing ice cream though!
mostlygroovywww.canadianprotein.com Buy Canadian and less expensive
I buy in bulk - 6KG. It’s a great deal.
