Ozempic vs monjaro

I’ve been on ozempic for pcos for almost a year. I’m now on .25 mg just to maintain my weight. My insurance will no longer cover it so I have to pay out of pocket. I was trying to find a 2mg pen because that will last me 8 months but I can’t seem to find one. Should I switch to monjaro because there is more of that available and what is the equivalency between .25 mg ozempic and monjaro?
