Another option nobody mentioned — some people split their dose when going up. Instead of one 12.5mg shot, they do a 7.5 + 5 split (one shot, two injection sites, same day). My endo actually suggested this and it dramatically reduced my GI sides when titrating up.
Obviously this only works with vials/compound, not the auto-injector pens. But worth asking about if you do decide to go higher eventually.
Not medical advice, just sharing what worked for me
