Hey, I tried to tell 'em about Select. Also IsoFlex is pure trash guys. It used to be king when Isolates were not as common, but it's spiked, mixes absolutely terribly, still caused gas(both of these shouldn't happen with a quality pure iso), and is unnecessarily expensive. I'm saying this bc I used it for YEARS, and I wish I knew better.
I can't digest lactose but Select doesn't bother me 9 or 9.5/10 times, even on days when I eat spicy foods(which is usually a lactose no no). I noticed a MAJOR difference moving from a pure ISO to Select, in terms of strength, recovery etc. It is more like a whole food whereas ISOs are heavily processed. I'm loyal to Select above all else now.
My personal experience switching to a blend was before I would drink an isolate, I would get a bit of energy 45-60 mins after drinking it, then crash, also it wouldn't fill me up, it would have no effect on hunger. Now if I am working or exercising while fasted, Select keeps me satiated and there is no crash, bc it doesn't produce a HUGE insulin spike. Basically I started to feel the same drinking an Isolate than if I were to drink a sugary soda, which is a problem.
For me at least, Select's science is legit. I started to look for a new protein when I realized all this was happening and came to the conclusion that my Isolates are too insulinogenic and that's why I was experiencing what I was, and when I read Select's science confirmed my observations, I was sold.
tl;dr, Select is the god's protein. These are my personal experiences though, but the science seems to validate them.
