She remembered the first pen, the red one. That was for “starter” doses: 0.25mg, then 0.5mg. Counting clicks was simple then. You turned the dial, heard the soft ratchet-ratchet-ratchet , and stopped at the tiny line for 0.25. Eighteen clicks. Easy.

After four partial doses, the internal piston had moved exactly 68 clicks (4 x 17). That was exactly two full 2mg doses (2 x 34 clicks). The pen thought it was empty after two doses, not four, because the remaining 4mg were still in the reservoir but the piston had locked due to uneven gear pressure. ozempic 8mg/3ml pen clicks

It was gray, almost industrial-looking, and held a concentrated 8mg of semaglutide in just 3ml of liquid. That meant one thing: fewer clicks per milligram. She remembered the first pen, the red one
