>If you are dealing with hair loss you won't see any grow back with >des, only with melatonin implant does that get it to grow. Deslorelin works in the same way that Lupron does. There are some ferrets for which Lupron or des won't work because the tumors have progressed to the point that the glands aren't receiving the hormone signals that these drugs use. Similarly, there are cases where surgery isn't a cure, because tumors can regrow, even after both adrenals have been removed. One of the clinical differences with deslorelin seems to be that the timing of the medication is different. Obviously it lasts longer, but the onset of effectiveness seems to be more delayed as well. As to fur regrowth with Lupron and/or Deslorelin, fur does regrow with both. Certainly, melatonin seems to help with both fur and muscle mass, but Lupron/des will help fur come back. For just one of my experiences, see the pictures at http://www.washingtonferret.org/support.htm Angelo is a ferret that I nursed back to health, and you can see the results for yourself. He was on Lupron and not melatonin. Kevin Farlee Washington Ferret Rescue & Shelter [Posted in FML 7712]
