What P21 is

Research peptide, plain

A newer peptide studied for how it relates to the birth of new brain cells.

Early research, thin data, honest about it.

Your brain can actually grow some new cells in certain areas. P21 is studied for how it relates to that process.

What it is: a lab-made peptide. (A peptide is a tiny chain of the building blocks your body uses.) It's a relatively new research compound.

What it does: researchers study how it relates to neurogenesis, the process of forming new brain cells. It lives on the Brain + Mood shelf near Dihexa.

What it actually does

P21 is studied for how it relates to neurogenesis, the process where the brain forms new cells in certain regions.

It's a newer compound, so the research is early and limited. We'd rather say that plainly than dress it up. We're describing the mechanism studied, not promising a result.

The research so far

P21 is studied in neurogenesis research. It's newer, so the data is limited. You can browse the literature on PubMed. (No clean single PubChem entry, so structural rows are left off rather than guessed.)

Featured angle

The neurogenesis angle

P21 is studied for how it relates to forming new neurons in lab models. The research is early-stage and the file is thin, which is worth knowing before you dig in. None of it is a claim about what it does for a person.

The backstory

P21 is a more recent addition to neurogenesis research.

  1. Designed for study

    Built as a tool to study neurogenesis.

  2. Early file

    Research is limited and ongoing.

  3. Where it stands

    An early-stage research peptide. We're not telling you what it does for you, just the pathway studied.

Buying P21 in Canada

The short version

Read the COA before you buy, not after

Every batch ships with its Certificate of Analysis, right here on this page. A number on a label means nothing without the paper to back it.

Same-day, packed cold

Order P21 in Canada and it's out the door today. Cold chain, domestic shipping.

Freeze-dried vial

Lyophilized powder, sealed. No ice required for shipping.

Sold for research

Not for human consumption. Nothing on this page is a medical claim.

What is P21?
P21 (P021) is a synthetic peptide studied in neuroscience research for how it relates to neurogenesis, the formation of new brain cells. Sold as a lyophilized powder for research use only.
What is P21 studied for?
P21 is studied for its relationship to neurogenesis in early-stage cell and animal models. The research file is limited, and nothing here is a claim about what it does for a person.
How is the purity verified?
Every batch is tested by HPLC to at least 99% purity, and the Certificate of Analysis for that batch ships with the order and is shown on the product page.
How should it be stored?
Store the lyophilized powder cold and protected from light. Keep it sealed until use to maintain stability.
Does it come with a COA?
Yes. Every batch ships with its Certificate of Analysis, shown right on the product page, so you can confirm purity before you buy.
What does "research use only" mean?
It means this product is intended strictly for laboratory research. It is not for human or animal consumption, and nothing on this page is a medical or therapeutic claim.

Not for human consumption. Not approved by Health Canada. For in vitro research only.
