That's what I was wondering. I still have some old stuff in stock, so I think I'd better "collect" all the bottles from now on...

Yes, liquids are much easyer to mix, though their expiration is always my concern. I didn't have problems so far, but for some reason I'm persuaded that powders, generally speaking, last longer.

However it is, thanks for the fresh news about the 5.3 kit.
