I found a site Abbey veterinary supply after days of research that has Betamethasone sodium phosphate and betamethasone acetate injectable suspension for sale named BETAVET, it says for horses only but from what I read and looked into the maker American regents website I cant see any difference in human and horses version. It is FDA approved and exactly what I am looking for. You guys are much more well versed than I am so I thought I would reach out to get any feedback if possible.
