Small quote I need clarification on:
"Alternatively, you can pick the bonus the unit receives ,but if you do this you can not choose a bonus that has already been taken by another unit until all six combat drugs have been taken once each."
This basically means, I can take 6 units, 1 for each different drug, but after that I can give any drugs I want to any more units I want, so I can proceed to stack drugs how I want.
I wish Talos got combat drugs or some Coven Stimulants. I got 6 of them. Trying to revitalize my truekin army.
