I will give you the basics of what Opti told me in regards to this question when I posed it about several other items going OOS and then being replenished on his site in a relatively short period of time, without a change in the latest Janoshik batch testing results. Everything he ships is tested. If it's available for purchase on his site, then he has a Janoshik test for it. What happens is that when the location(s) that he ships from go out of stock on an item, until they are replenished, they will show out of stock on the website. If that inventory is replenished with stock from an existing batch, then you won't see a change in the Janoshik results as it's still the same batch you're getting. You may wonder "why isn't every bit of a batch ready to go and available both as inventor on the website, and as inventory at whatever location packages are shipped from?". The shortest answer is simple; it's never a good idea to keep all your eggs in one basket, and that applies double for this type of business. I hope this information helps to put your mind at ease and assure you that you are receiving a tested product with no quality/potency issues.
