Is purchasing SN from ec21 safe?

[snooperdooper]

Skeptical about purchasing it from countries outside of the US, but only way I can do it it seems. Also, these prices seem crazy from the research I've done on how much SN costs.

i found it based on the post, just used"Y" and it came up. however the quality is not listed i see some posts by other users asking questions and being answered by the seller but the quality isnt listed.

edit: i found a few more listings and it does appear to be SN but quality/purity isnt shown maybe it is but I cant read the language
