Longer dosing frequency?

Insurance covers my Zepbound at $25/month on single dose pens, so I’m not changing to vials or multidose. Starting weight 221, currently about 189 and interested in increasing my food for muscle gains. What dose frequency have folks used? I know every ten days is pretty common. Anybody dosing every two weeks?
Easy option would be to go back down to 2.5mg but I’d like to keep my prescription fills on time each month. I’ll probably change insurance next year and uncertain if it’ll get covered again.
