Tasted it and immediately ordered another!

I actually don’t even love the real cream eggs but I thought this would make a cute “Mom’s Easter Basket treat.” This Diesel flavour is soooo delicious! I had to get another while they were on sale. I highly recommend Brown Sugar Boba, too! 🤤 Happy Easter everyone!

Good but…..

It’s a very, very good whey isolate but I wish it was a bit more flavorful. I don’t get much “maple” flavor to be honest. I will try other flavors. Pumpkin spice is my fav so far

Pretty good

Not a bad product. The delivery was fast. Only downside is the chalky aftertaste.

In Walmart 40$ regular

You guys do realize that the same protein in Walmart is like 40$ on regular price?
Im giving 5star for protein btw,not the store

Thanks for the review. That is not the same product. The one you are referencing is whey concentrate. The one we sell is whey isolate. The only thing the same between them is the name.

Great protein but a little too sweet for my liking, I ordered the peanut butter chocolate and found it to be more sweet then I thought it would be

Best I've tried so far!

Biggest thing for myself was the fact that it mixes really well and I don't have to deal with clumps of undissolved powder in my shakes. The price was better then I thought and shipping was faster then I thought. Definitely buying again!!

Not really a Canadian product

Used to be my to go protein but after they jacked up the price i wrote to Perfect Sport and asked why...their answer....as the price from the Whey they buy from the US as increased they had to increase their price. Can you reallly call yourself a Canadian product when its 100% made with US material lol. Cant recommend cause of their false advertising and lets be honest crazy price (180$ with taxes in Qc for a 5 pound)
