Even as an ambassador, I do have to say it doesn’t provide the same benefit as my full whey protein shake with 2% milk as my liquid base. However, I have found it to be a great addition to my protein shake when I can’t have my shake immediately after my workout (not at home right away, can’t eat, super dehydrated, etc). It helps me kick start the rehydration process for me, especially after big and hot days and extends out the post-recovery fuel window for me so I can get back home in time to make my protein shake.
There might be a huge element of placebo in there, so take this with a grain of salt. I also agree that the taste is not great. It took me months to get used to it, but even then I have to just go for it and chug it as quickly as possible.
