So maybe there is something here after all. I am on Viibryd 5mg, which was yellow on my genetic test and it seems to work well so far. I've been informed by my doc that these test are helpful in that they tell you which meds you metabolize best but they do not tell you exactly how the med will work. Well I knew that, but I was about to give up on it but figured it's a good baseline to follow so we went with the Viibryd.

Pdoc also mentioned brain scans that can be done to determine if you're likely to do well on a particular AD I guess they take scans of your brain then compare them to other depressives who have had success with particular medicine. Then they prescribe the medicine based on the person who has similar brain activity as you. Even in this case it's a toss up as to whether or not the med will work for you. But at least you can have some sort of science behind your choice.
