Okay so i have a bottle of test prop with about 4 cc's left in it and when i pulled it out this morning there is a wierd crystalization going on inside it. At first i thought the class may just be cracked but as i look closer it looks as if something is like growing or something in the top of the vial towards the top like a wierd spider web of crystally ice sickles or something. I store the bottle at room temperature about 73 degrees so its def not ice. Does anyone have any idea of whats going on here?

Thanks for any help
