Not EU based myself, but friends of mine who’ve used EU domestic stuff always mention one name: Venom.
People talk about it like it’s brewed in a monastery at 3am. Oil so clear it looks like distilled mountain air. Smooth enough you start checking the vial wondering if it’s even real. Jokes are that it’s filtered through unicorn hair, mixed with the tears of untouched virgins, and blessed before crimping.
Obviously that’s all bro-science poetry, but reputation-wise it’s one of the few EU brands people consistently describe as clean, smooth, and boring in the best possible way. No drama, no mystery PIP, just does what it’s supposed to do.
As always, that’s just forum lore, not gospel. In the EU scene though, Venom is usually the one people mention without immediately adding a warning label.
