Green tea extract...that's what it looks like to me. Lmao. Use a reagent kit to help along you search. No one
Will be able to tell you what it is by looks alone.
Yeah indeed, I'm sorry but there is no way we will be able to tell you what that is. Buy a testkit and find out for yourself, that's the only way except for lab testing to have any indication. Since guessing at it might do more harm than good and as such isn't allowed, I'm going to close this thread. Welcome to bluelight anyway, if you have other questions don't hesitate to ask :D
