I have difficulty understanding why you refuse to put an expiration date on the boxes of Chlorella. It seemed to me that it was compulsory. Don’t you think that this refusal does not really commit you to the purchase ?
I will answer your “remark” or “question” below without delay.
You are right, a date of consumption or optimal use is mandatory on all products sold.
You will find a best before date on the bottom of each jar.
Today our date is March 2017.
Hoping to have totally reassured you
