>>40625088 (OP)There have previously been a few controversies with people claiming their EEn might have been EV because they were getting poor levels. I have had a similar experience with EEn, still have no idea if my body is just weird with that ester or if there was actually any truth to those rumors. Ultimately nothing has been proven and they were largely unfounded.
More worryingly, they have had some issues with their vials being piss yellow, either burnt or oxidized. This too has happened to me and I got a replacement sent out. Supposedly Astrovials is a rebrand of OE labs who were also infamous for yellow vials, and they shut down after pulling an exit scam and not fulfilling paid orders. Astrovials has had a similar situation last year where they were taking preorders for vials which hadn't been made yet, but they did ultimately ship those orders thankfully and have had no similar events since.
Currently I am still using Astrovials and i am having no issues with my current vial. They are one of the most popular homebrewers and chances are you will be perfectly fine. That being said i advise a bit of caution given their past record and would recommend you also consider alternatives. Voix Celeste is another popular homebrewer located in the EU, they have had no such controversies so far as I know.
