Where, indeed, can one obtain antivenom of any sort? Well, if you are well connected, you might be able to get a dr to sign the IND forms for you, if you're going for a crotalid av from outside the US--ie, other than CroFab. If you need CroFab, then you migth be abel to get a Dr to order some for you. Or you might find other ways to get your IND number and buy directly from the manufacturer.
Are you even in the US? If you're not, then what I've just said is useless to you.
