HST and Mag 10

I saw a previous thread on this topic, but I can’t seem to find it. My search engine is all screwed up. I’m getting ready to start an HST cycle, as well as Mag 10, and I wanted to know at which point in the HST cycle I would get the best results from the Mag 10. I’m only going to be able to use one 2 week cycle of Mag 1o. Thanks.
