Medically reviewed by Charles Kamen, MD, board-certified neurologist ·

P-21 (also written P021) is a peptide studied in the context of cognition and neurogenesis — the formation of new neurons. It has drawn research interest for potential cognitive and neuroprotective applications.
At LiveNow Longevity, P-21 is considered only after a medical evaluation by board-certified neurologist Dr. Charles Kamen, MD — a brain-and-nervous-system perspective most wellness clinics cannot offer.
Inclusion of any peptide in a protocol is determined by Dr. Charles Kamen, MD, after a complete medical evaluation. Individual results vary, and we do not guarantee specific outcomes.

Frequently Asked Questions
What is P-21 used for?
P-21 is a peptide studied in the context of cognition and neurogenesis. It may be considered as part of a cognitive protocol when medically appropriate and after evaluation. It is not an FDA-approved drug.
Why see a neurologist for P-21?
Cognitive peptides act on the nervous system — Dr. Kamen's area of board certification — so your protocol is designed by a physician trained specifically in brain function.
How is P-21 administered?
P-21 is prescribed and dosed by Dr. Kamen based on your evaluation. When part of a protocol, the schedule and form are individualized to your goals.
Is an evaluation required?
Yes. An $88 medical evaluation precedes any cognitive peptide protocol.
