There was a guy on the board a few months ago(Bigrif I think) who aspirated and he was in a vein. He tried injecting a little, just to see what it would do. Nothing happened except his adrenaline shot up a little cause he was scared.
Just always remember to aspirate and you'll be fine.
BTY. Has anyone seen Bigriff on this board lately. Last time I saw him he was doing a huge cycle. Just wondering how it turned out.
