per administration
Only animal or lab studies exist — no human study has set an amount.
Quick start
P021 at a glance — the figures, plus how it's commonly run. Reference only, not medical advice.

- How often
- Every day
- Where
- Commonly subcutaneous Sites and rotation
- Time to steady level
- ~30 hours — about five half-lives
- Storage
- Dry vial kept cold and dark; a mixed vial in the fridge at 2–8 °C. Details

Published research contexts for P021 describe 1–5 mg per administration. Descriptive only, not a recommendation.
No human pharmacokinetics; the figure is an order-of-magnitude placeholder from rodent work where it is reported to be orally active.
Evidence is preclinical: a ciliary neurotrophic factor (CNTF)–derived, adamantylated peptidomimetic studied in rodent neurogenesis and tau models and reported to be orally active. No human dose-ranging data exists and no amount or schedule is established, so the figures here are nominal and no schedule table is shown.
Modelled level — every day
1× is the peak after a single dose.
- Steady-state peak
- 1.07× single dose
- Time to steady state
- 30hours
- Administrations
- 7/ week

- P021 CNTF-peptidomimetic literature (Iqbal/Kazim)A CNTF-derived compound reported to raise neurogenesis and lower tau pathology in mouse models; no human dosing literature.
