P21
Peptide discussed for neurogenesis/cognitive support.
We have not published an audit on P21. Everything below is reference material, not our own reading of the literature, treat it as a starting point for questions, not as a grade.
How it is thought to work
Potential neurotrophic signaling.
What sources report
These are figures published elsewhere, reproduced with their source. Peppersite does not recommend an amount for P21 or for anything else, and nothing below has been checked against the study it came from.
| Amount | Frequency | Route | Reported by |
|---|---|---|---|
| Practitioner ranges vary; commonly ~1 mg SC daily - provider-directed | once dailyPer provider direction · Per provider direction | subcutaneous | Commonly published practitioner dosing range - provider confirmation required. |
- once dailyPer provider direction · Per provider direction
- subcutaneous
- Commonly published practitioner dosing range - provider confirmation required.
- Compounded; varies · Reconstitute with bacteriostatic water
The reference sections above are imported from our compound knowledge base, which classes the evidence for P21 as theoretical. That classification is the knowledge base’s, not ours, our own grade appears only where an audit is linked above. Research use only; nothing here is medical advice or a protocol.
