Obtaining free hyaluronidase?

Crossposting from the dermatology forum: I'm wondering if anyone has advice on how to obtain free hyaluronidase for our cosmetic teaching sessions. We have tons of filler, neurotoxin, etc, through various resident cosmetic grants, but I can't find any resources for obtaining hyaluronidase. We currently borrow it from our cosmetic attending, but it would be ideal to get our own supply for multiple reasons. Thank you!
