USN Blue Lab 100% whey is a great all around protein. Whey is one of the most widely used proteins, therefore there tends to be the most options when shopping for a whey protein. There are tons of purely whey protein supplements on the market, and the easiest way to break them apart is by ingredient quality, mixability, and flavor profile. USN Blue lab is right at the top of the list in terms of ingredient quality. Where many whey proteins will be a concentrate/isolate blend, USN goes a step further, with the first ingredient being a hydrolyzed whey protein. This means it delivers a higher absorption protein blend than most others on the market. In terms of mixability, Blue Lab whey mixes as well as most other whey proteins, with no real issues like clumping or gritty texture to speak of. Finally, every flavor we've tried has been great. The Salted Caramel has been a best seller since we started selling USN, and the PB&J is unexpectedly one of our favorites. To read more about what sets USN Blue Lab apart check out the blog here.
