What is Testagen?
Testagen is a very short peptide, a chain of four amino acids. It comes from a Russian research program in St Petersburg that has built a series of these short chains since the 1970s. Chemists worked out its recipe from the mix of peptides found in the pituitary gland, a small gland at the base of the brain. It has been studied in three places: inside human cells grown in a dish, in birds whose pituitary gland had been removed, and, oddly, on copper.

Labeled quantity is net peptide content, not gross salt weight.
Testagen Research & Reference
What Testagen does in published studies, and how to work with it in the laboratory, are covered in full on two dedicated pages rather than summarised here, so neither the evidence nor the handling detail is cut short.
Certificates of Analysis
Every batch is tested by an independent laboratory before release. The certificate covering this batch of Testagen, and its safety data sheet, are below as PDFs, so the figures on this page can be checked against the source.
Frequently Asked Questions
Is Testagen independently tested for purity?+−
Yes. Every batch of Testagen is tested by an independent third-party laboratory using HPLC and MS-UPLC, confirming purity and mass identity before the batch is released. Pure Peptides does not test its own material.
Can I see the Certificate of Analysis before buying?+−
Yes. The Certificate of Analysis for the batch currently in stock can be viewed and downloaded directly on this page, before you place an order. Each certificate states the batch number, the measured purity, and the date of analysis, and can be verified independently with the issuing laboratory using the report number it carries.
What does "Research Use Only" mean?+−
It means Testagen is supplied for in-vitro laboratory research and for no other purpose, and must not be administered to humans or animals. Testagen is legal to purchase in the United States for in vitro and non-clinical laboratory research. It carries no FDA approval or therapeutic indication for human use. Testagen is not a scheduled substance under the Controlled Substances Act. Sold strictly for qualified research use, not human or veterinary administration.
How is Testagen shipped and stored?+−
Testagen ships from US stock with cold-chain packaging and full tracking; orders placed before noon EST on business days are typically dispatched the same business day. On arrival, store the lyophilized powder at -20°C or below, dry and protected from light.
