i dont know if this is relevent or not but i thought id give a few reviews of the flavors on there since you guys were talking about the premium vs BSL vs regular....
their strawberries and cream premium flavor is amazing... its my favorite by far. the premium orange creamsicle (or something like that) is also very good for protein shakes.
for my carb mix i use their premium orange juice indulgence and its awesome... i dont think i wouldnt get it for protein though, but its great for amino mixes, carb mixes, etc.
my current post workout shake is a mix of 60 grams carb mix with premium orange juice indulgence, and 30 grams ON 100% whey french vanilla cream.... that mix of flavors seriously makes it taste like an orange julius
as for other flavors, the lemonade didnt impress me and is hard to get down (in a WMS/dex/malo carb mix). premium french vanilla cream isnt anything special... just a vanilla to me.
i ordered a few bottles of just the flavoring systems... its around 5 bucks for 50 grams of flavoring and its a GREAT way to mix up old boring protein shake flavors
gotta love trueprotein
