Here is a past post by Sukie that should answer most or all of your questions about the Deslorelin implant. It includes a link to the website of the manufacturer in Australia, Peptech.

I am just putting things together once more to help people whose
veterinarians need this info, having been asked for it again today so
this is revised for general use and has some added information.
The implants are not DISTRIBUTED in the U.S. but deslorelin as a drug
IS approved by the FDA*. Peptech is working to try to get a future
U.S. distribution chain worked out but I am not privy to details.
Originally, there was a miscommunication btwn two branches of the
FDA. Neither branch knew that they had miscommunicated, so paperwork
sat and sat. One day in a reply from the FDA I got lucky enough that
the branch which thought that it was not okay for most to import
Suprelorlin copied to the veterinary branch. That was NOT my doing.
It was just plain, dumb luck, and I guess if someone is going to get
lucky that was a good place to get lucky. The person at the
veterinary branch then wrote to both that person and me saying pretty
much, "Hey, here's the approval record for deslorelin so I don't see
the problem." * Then importation got much easier for all. We've all
run into miscommunication problems all over the place in the past,
including some involving us -- and I did that again yesterday, too,
and I know that everyone has been in a similar spot at times, so each
of us can see that this sort of thing could also happen in a busy hive
of productive professionals. What's important is that they responded
so rapidly and constructively as soon as the miscommunication was
discovered. Kudos to them for that.

noting that the dog products have been used in ferrets.
and ask for ordering information for the U.S.
Peptech takes care of almost everything except for parts of the
veterinary hospital letter to
accompany the imported items. Sometimes countries change the
numbering systems for permissions and the like, so each time check the
letter template they send out since it may have changed.
Yes, they DO provide a template for those hospital letters which will
accompany the medications. That gives the designations of various
approvals and more. I don't know if they send along the list of
current studies though I have sent them the one I put together for my
vets.
Here is the vet study info I sent to my vets which was part of their
letter. I placed the U.S. studies first because the FDA has at times
weighed U.S. studies more highly than non-U.S. ones for some other
things (such as its current consideration of sublingual
immunotherapy)and I put the newest U.S. article first. More on these
can be found in the Pub Med listings of studies:

The implants are large so a bit of Iso to give it and a bit of
surgical glue on top can make sense. Not everyone does that, but if I
were getting something that size I'd want numbing and some do try to
scratch the area which is why our vets put them a bit below a scapula
near the spine.
If a ferret needs subcu it needs to be known that this may cause the
implant to not last as long but so far no one has mentioned any hazard
from that (saying that because we once had to check for the needs of
one of our ferrets).
Suprelorein does not work for all but does work for many. It appears
that if carcinoma is present it may pay to put in a new implant every
6 months.
I have been told of one case where the FDA in California opened and
inspected the package and was told that if that happens there is a $50
repackaging fee. So, just an FYI on that.
