Interestingly me and my friend were talking yesterday as both of our recent 20 mg vials seem weaker than the 10 mg we had before, definitely noticed more hunger once the 10mg vial ran out and switched to 20, even after uping to 4mg from 2.I am on 4mg right now and barely feel anything appetite wise, still can eat like a pig but less food noise overall, a little less craving, will move to 5mg , first time on GLP and was hoping for more . using GG 20mg vial , tittrated up from 1mg per week to 4 mg in 3 weeks. No sides
