P-21 Amidate Dosage Guide: Protocols, Calculator & Safety
Everything you need to know about P-21 Amidate dosing — protocols, safety, and where to buy.
Half-Life
No established human PK - unknown. P-21 (P021) is a preclinical compound; rodent studies used chronic oral or subcutaneous dosing and demonstrated oral bioavailability and blood-brain-barrier penetration, but no validated human half-life data exist.

Dosing Protocols
Beginner
- 100-200 mcg/day oral or intranasal, once daily, 14 days
Intermediate
- 200-400 mcg/day, 1-2x daily, 21-30 days on / 7-14 off
Advanced

Commonly Stacked With
Best paired with NA-Semax Amidate for a once-daily long-half-life nootropic stack. Also stacks with Selank, Cerebrolysin.
Additional Notes
P-21 (P021) is a preclinical, research-use-only compound. No human pharmacokinetic, dosing, or safety data exist; all published studies are in rodent models using chronic oral or subcutaneous administration. The microgram protocols shown here come from vendor and community sources, not clinical trials, and should be treated as theoretical. Note: base P021 is already C-terminally amidated (Ac-DGGL(A)G-NH2), so the "Amidate" label does not denote a distinct or more stable molecule.
