Hello, please inform the lot number of Vitamin C used in the mix. The staff will inform the relevant department to check the quality for you.

If there is enough substance left, do another set. and mix it for your own use We recommend trying the combination ascorbic acid (standard) into phase A, then mix A with B (standard powder may be difficult to dissolve), or You can try sending the lot of ascorbic to the staff to check first.
