Best Protein on the Planet Bar None. But order processing is ridiculously slow.
By Bill
Longtime user. My wife likes the Native Whey Concentrate unflavored, while I use the unflavored New Zealand Whey, which has a rich taste. I have used these and other whey and casein products and can say with assurance that these are as good as it gets. Years ago I used several big name whey products from brick and mortar retailers and would get low glycemic reactions it felt like when exercising. Protein Factory is consistent, ships promptly, even with the pandemic, we get our shipments in a couple of weeks. I buy directly from Protein Factory, rather than Amazon, of which we're prime members, because it might help the profit margin for PF.
