I know one guy that uses it, but he's a doc. So he can take care of himself. My cortisol is through the roof always. Doc said to try Phosphatidylserine. Couldn't get any easily. So I tried Relacore, which has it as an ingredient. I actually felt better within the first day. Going to use it for a while and get labs drawn. Then try Phosphatidylserine only, not a blend.
