I’m trying to buy real TB-500 (the active 17-23 fragment,), but I’m seeing a lot of vendors selling products labeled as "TB-500" that actually seem to be full TB-4, if I'm not mistaken tb500 should be tb500(889da) in the CoA and not tb500(tb4).
have i understand it correctly?
Any trusted sources that reliably sell the real tb500 and not tb4?
