I got mine in middle of November, and I believe them to be good. I ran 4-6iu per day and maintained scale weight while getting leaner. I ran 4 kits though, and after 1 kit of novos I have more results. I am dieting. A lot harder and running 10iu per day so that could be the different. Just didn't think I'd see results like this after 1 kit. Anyway, my kigs DO have the two layers. First one is thin and real white the bottom is more off white and is the bulk of the powder.
These are the stamped batch, with overlapping labels and great vacuum. They bubble like crazy when reconned, and take a few minutes to dissolve. They are not as cloudy though as novos, which may be due to more filler or impurities in the novos?
