I just wanted to post this for everybody using or thinking of ordering Kuinone.
Due to the large number of reports on Kuinone staining, we are using a batch that has a much paler yellow color and it does NOT stain. I will see how this batch fares and if it is liked just as much as the staining batch we will stick to using the non-staining version. Vitamin K2 can vary in color from almost pure white to bright yellow/orange. People who have used the vitamin K2 pills from VRP, Relentless Improvement, etc have seen this - i.e. they all vary in color even though chemically it is the same vitamin K2 (or at least it has the same CAS number).
Also, we are now using an odor-free DMSO as a solvent for the vitamin K2 and this type of DMSO also seems dramatically lower the incidence of skin irritation as well.
