I ditto what Cathy said.. I do Synarel - re stock availability - it has just been out of stock for weeks in Aus and became available again last Mon. Give your chemist a week to get it in as its not needed much outside of ivf.
I use it because it's portable and unobtrusive you can administer it anywhere in front of everyone if need be, doesn't need to be kept cold, is a similar price ( I got $97 back through PHI). They all make you prone to headaches on and off.
