Leanfit whey protein isnt great for typical gym go-ers (EAA mix). They also don't mix all that well. Have to talk about the whey isolate, in which case this is better priced.

The leanfit is a whey blend. Meaning it mixes a whey concentrate and a whey isolate together. When you start getting into a straight whey isolate prices increase almost double. Isolate is more refined and packs more protein per scoop. For instance that leanfit is 72.7% protein per scoop when you jump up into an isolate product you can get into the 90% protein per scoop. Whether or not that’s important to you is your decision

Leanfit (2nd version) is the cheapest but one scoop doesn't have enough leucine to trigger muscle protein synthesis completely. You need 2.5g leucine in a meal with protein to completely trigger MPS but leanfit only has 1.88g so you'd probably need a scoop and a half. Just something that I think is important if your trying to maximize progress like I'm atleast.

Get the other one that costco carries. White packaging. Leanfit Whey Protein. Almost same micros. Much cheaper and I find better tasting.
