Suprelorin (deslorelin) implants may soon be available in the USA. Peptech announced today that they are in the process of seeking approval from the USDA: http://www.peptech.com/peptech/content/Frame_Def.asp?ID=5 (first PDF "Peptech expands market potential for dog contraception") Hopefully they will get approval, as the implant lasts longer than Lupron, and is quite a lot cheaper (although I guess they could up the price) I have a copy of the results from one study ("Wagner, R.A., C.A. Piche, W. Jochle and J.W. Oliver. The treatment of adrenal cortical disease in ferrets with deslorelin acetate implants") if anyone would like to read it. (: shona [Posted in FML issue 4791]
