P021 Reference

Plain English

What it is

P021 is a small lab-made peptide based on a natural brain-support protein called CNTF (ciliary neurotrophic factor). It is an investigational compound studied as a possible Alzheimer's treatment, not an approved medicine.

What people use it for

In nootropic (brain-boosting) circles, people mention it for memory, growing new brain cells, and lowering tau and amyloid, the proteins tied to Alzheimer's. Those ideas come from animal studies, not from results in people.

What the science shows

In mice bred to develop an Alzheimer's-like disease, P021 changed tau, amyloid, new-brain-cell growth, and memory. There is no human data showing it works or is safe in people.

The catch

P021 is a research chemical with no FDA-approved drug label, and the published work is almost all disease-model mouse research. The brain-boosting and anti-Alzheimer claims are unproven guesses pulled from animal work, not clinical evidence.

Reference summary

Mouse studies in 3xTg Alzheimer models report changes in tau, amyloid, neurogenesis, synaptic plasticity, and cognition. Human clinical efficacy data are absent.

Regulatory and posture

Categories

Cognitive, Longevity

Aliases

Peptide 021, CNTF-derived peptide mimetic, Ac-DGGLAG-NH2

Evidence posture

preclinical - Animal-model neurodegeneration signal only. Community nootropic and anti-Alzheimer claims are unproven and should not be treated as clinical evidence.

Regulatory status

No FDA-approved P021 drug label. P021 is an investigational CNTF-derived peptide mimetic studied primarily in Alzheimer-model animals, not an approved nootropic or dementia treatment.
