I use to sell Theralac and the manufacture when they ship to the wholesale distributors the shipping boxes have a sticker on them or they used to that states to refrigerate apon arrival when you receive ths products.. I always kept them in a refrigerator in my garage we do not use it for food only cold drinks.
I actually have been selling Threelac since 2003 and have decided to no longer be tied to the computer on a daily basis so I am selling out all my GHT products at a discount I posted in the market place forum just FYI for the person who mentioned they use Threelac..
