When using the red starter pen, the medicine can be distributed in two primary ways based on the official product information :

| Week of therapy | Dose | Which pen | Doses from that pen | |----------------|------|-----------|----------------------| | 1 | 0.25 mg | Red starter pen | Dose 1 | | 2 | 0.25 mg | Red starter pen | Dose 2 (pen empty) | | 3 | 0.25 mg | Second red starter pen | Dose 1 | | 4 | 0.25 mg | Second red starter pen | Dose 2 (pen empty) | | 5+ | 0.5 mg | Blue 0.5 mg pen | 4 doses of 0.5 mg |

Arthur turned the box over in his hands. It felt light. "So," he asked, his voice dropping to a conspiratorial whisper, "how many doses are actually in this thing? I’ve heard people say they can get more than the label says."

Arthur took the pen home. He placed it on the kitchen table and stared at it while he ate a bland dinner of grilled chicken. The pen looked like a futuristic writing utensile, sleek and blue.
