Low-T injections changed my husband

Back in October 2018 my husband started low-t injections and almost instantly he changed from a loving, caring husband to a jerk, insensitivity, quiet man. No matter how many times I try to tell him to stop, he’s answer (and that’s if he speaks to me) is that he will not stop.. not sure how this can be legal, for physicians or whatever kind of people that work at those low-t centers to be injecting legal drugs into people without caring about the consequences.. i’ve heard a few stories about men doing the same injections and I always get the same answer. The mood swings and changed in personality.. not sure what to do with him anymore. Has anyone heard or had an experience like this?

Hi I don't have any personal experience with this..... maybe his dosage is too high. Has he said why he doesn't want to stop? Maybe if you explain you don't want him to stop completely but just to have the dosage regulated so that he gets the right level so everyone is happy?
