IKinda on-topic. I went to GNC. The only GNC multi-vits I could find I bought. There arent different kinds are there? Only one? It doesnt say saw palmetto on the back. I may be mising it though.
If you're looking for something to offset decreased sex drive from Propecia use, its the Mega Man Multivitamin. Black label white bottle, gold writing. They do contain saw palmetto.
It is advised you only use one a day for a handful of days at the most, just to kickstart the sex drive again. Usually works. Those things are potent as hell and I personally wouldn't suggest using them as a daily multivitamin.
Hair lost during any shed is grown back. Its not forever-lost hair. Its just a larger # of follicles entering the normal dormancy phase at one time than you'd normally see... to recycle back into growth phase again later.
