I got great awnsers from an email exchange with Brett from texas select vapor. Was very helpful, basically all the 'classic flavours' on the website have not changed formula, just the pg vg ratio. So in theory should be the same test results, he also explained how some flavours have been discontinued and have changed formula.
It turns out the UK sellers still have the older discontinued flavours in stock and these have not been tested, they do not have the newly formulated flavors yet and are still selling the old type, even after asking they told me they WERE tested and diketone free, glad I didn't take there word for it. Took alot of hassle but got the awnser I was looking for in the end.
Hope this helps someone. (This may also apply for shops in the USA that still have left over older stock. All the new stock has DA/AP with a green tick on the bottle).
