A week without movement on the scale is annoying but usual. Only after several weeks of no progress, defined as under 1 percent body weight lost in two weeks or 2 percent in four, would I consider it a real stall and change something. Not sure what the concern with pens is, since the medication is the same whether delivered that way or from a vial with a syringe, assuming proper handling. Switching formats is always an option, or the cartridge can be used like a vial if preferred.
Just sharing details. I'm a 25-year-old male, 171 cm, now 86.6 kg after beginning at 103 kg. Eighth week on reta at 3 mg. Daily intake sits between 1200 and 1400 kcal, sometimes lower. Loss had been steady until the scale held between 86.2 and 86.6 kg. I can manage larger meals yet still eat little; being able to eat breakfast again shows the food noise has dropped, which matches how the medication is supposed to work. A refeed attempt did not move the scale. Using a pen and wondering if it has lost strength or is no longer effective. Also unsure how maintenance calories are calculated because online tools suggest 2000 kcal, which feels excessive. My routine includes 5-10 km runs three days a week, 1.5 hours of football twice a week, and daily weight training. Looking for input.
