What's New in Peptide Ninja
1.9.0
September 14, 2026
New: Titrate a dose right on your existing schedule — pick which upcoming dose the new amount starts with, no new schedule needed. New: Took a dose a day or two late? The app offers to shift the rest of your schedule to match. Forgot to tick one? A quick card lets you say what really happened. Log an off-schedule dose in one tap. New: Blood level charts now mark each shot's date, label every peak and trough, and let you run your finger across the chart to read the level at any moment. New: Over 70 compounds in the library, including eloralintide, the newer GLP-1 agents, injectable and oral steroids, and their ancillaries — each with dosing and half-life data. Improved: A redesigned syringe that reads like the real thing, with the dose marked on the scale and size buttons. Fixed: IU dosing for HGH- and HCG-scale peptides now tracks vials correctly, and the peptide list loads reliably.
