Highest EQ concentration for home brew?

[Mr. X]

I've been looking into purchasing EQ in powder form and making my own home brew. What's the highest concentration that that won't fall out of solution? I'm sure it has a lot to do with your BA percentage. I was looking at the universal kits from r**kits.

Thanks in advance.

i wouldn't go with much more than 400mg.
