bump on both posts before mine. hair loss is based on predisposition. here's my four problems with winny....it's water based, which means bacteria will grow very easily.....it's a short acting steroid, which means frequent injections.......it will tighten up those hammies, inviting a pull.....and it has little grains in it, which means that you may need to use a good size needle for these frequent injections. make sure you drink alot of water and use a strong alchohol to clean to top of the rubber stopper
