Okay so I ordered 2-fma and 5-mapb from Montfort and the 5-mapb does not look like how I imagined it. It is in chunks of brown crystal that look sort of like MDMA and smell like vinegar. I can't upload a picture right now and yes I know to test it, unfortunately my test kit was sent back because Bunk Police says they ship to PO boxes when they really don't. I'm not going to take any until I have a test kit.
Edit: I found this https://www.reddit.com/r/RCSources/comments/2uv6dg/5mapb_crystals_from_by/ and it made me feel a lot better since my crystals look almost exactly like that. Not sure where the vinegar smell comes from but it doesn't seem to be a smell associated with any other rc.
Almost 100% bullshit.
