P21 peptide 10mg research vial
The P21 peptide is a small lab-made compound of 4 amino acids taken from CNTF; one 10mg vial costs 5,300,000 VND ($210 USD). The P021 studies below link to PubMed, and the price shown for this vial was checked on 11 October 2026. The label in the product photo says P21, and research papers call the compound P021: ask on WhatsApp to confirm this vial holds P021 before you read the studies below as being about it.
What is P21?
CNTF, short for ciliary neurotrophic factor, is a natural protein that supports nerve cells in the body. That is the body's own protein at work, not a result for this vial.
In research papers the compound is called P021, or Peptide 021. The label in the product photo says P21.
P021 in rat and mouse studies
Read this first: the studies below are on P021, the research name for Peptide 021, and the product photo's label says P21. Ask on WhatsApp to confirm this vial holds P021 before you read these studies as being about it.
- Animal study, 2014. Old rats got P021, and the team measured learning, memory, new nerve cell growth and BDNF, a protein that supports nerve cells.
- Animal study, 2017. A mouse model of Down syndrome was given P021 and followed for early development and, later, memory.
- Animal study, 2024. A team in Bologna tested P021 in a rare brain disorder, CDKL5 deficiency, on nerve cells in a dish and in mice, and reported that it did little for the mice.
A small set of rat, mouse and cell studies, and our search found no human trial. Two of the three come from one group in New York; the newest is from a separate team in Bologna, Italy.
How to read this
Three things to weigh. The studies use the name P021, and the product photo's label says P21, so confirm the compound in the chat first. Two of the three studies come from one lab in New York, both in rodent models of memory problems. The newest comes from a separate team in Italy, and it tested the compound both in a dish and in mice. It came from a separate team, and it used a different model.

Questions about P21
What has research on P21 looked at?
Studies on P021: learning and memory in old rats and in a Down syndrome mouse model, plus a 2024 study of a rare brain disorder. Our search found no human trial.
Is P21 the same as P021?
Research papers call the compound P021. The label in the product photo says P21, so confirm on WhatsApp that this vial holds P021 before you link the studies to it.
Is this P21 the p21 protein?
No. p21 is also the name of a protein the body uses to control cell division. The P21 in this vial, written P021 in papers, is a small lab-made compound taken from CNTF, and PubMed lists 8 records for P021 with CNTF (our search of 18 October 2026).
