Best way to test rhodiola is to take it in small doses and see if your brain chemistry likes it. Not doubt some brands are better than others. I didn't have great results when I tried it, but I only tried one brand. I have read on Earth Clinic that 5 days on and 2 days off for supplements each week is wise. I try to give my body a break from all supplements once in a while. Good luck.
