Product Details
Testagen – Research Grade
Testagen from Cleared Peptides is a research-grade compound supplied for laboratory and analytical investigation. Every lot is third-party tested, and the batch Certificate of Analysis is published before sale. Specifications, CAS number and molecular formula are listed below.
Research use only. Testagen is supplied for laboratory research. It is not a drug, food, cosmetic, or dietary supplement. It is not FDA-approved. It is not for human or veterinary administration. This page does not give a dose or a method of administration. A study cited on this page describes that study’s own test article. It does not make this lot an approved medicine. To check a fact, open the PubMed or DOI link, confirm the authors and year, and match the paper’s compound name, CAS number, or sequence to the specification table. The full method is on the research desk page. Identity and purity for a lot are only what that lot’s certificate of analysis reports. An HPLC percentage is not a sterility result and not an endotoxin result unless the certificate prints those tests.

Testagen in Bioregulator Research
Testagen is a short synthetic peptide from the family of peptide bioregulators developed by V. Khavinson and colleagues, modelled on peptides isolated from testicular tissue.
Short bioregulator peptides such as Testagen are studied in cell-culture research on gene expression and chromatin interaction. It is often researched alongside other bioregulators such as Epitalon.
This summary describes published laboratory research only and makes no claim about effects in humans or animals.
Purity Testing & Certificate of Analysis
Each lot of Testagen is analyzed by an independent laboratory, with identity and purity (or composition, for multi-component preparations) reported on a lot-specific Certificate of Analysis. View current results on our COA page.
Storage & Laboratory Handling
Store at −20 °C, sealed, dry and protected from light. Allow vial to reach room temperature before opening. Minimize freeze–thaw cycles and handle according to your institution’s chemical-hygiene procedures.
Frequently Asked Questions
Is Testagen third-party tested?
Yes. Every lot of Testagen is tested by an independent laboratory for identity and purity, and the batch Certificate of Analysis is published on our COA page.
Can I see the Testagen Certificate of Analysis before ordering?
Yes. Lot-specific COAs are posted on our COA page so you can review analytical data before purchase.
What does Research Use Only (RUO) mean?
RUO products are supplied solely for laboratory and analytical research. They are not medicines, are not for human or veterinary use, and no dosing or administration information is provided.
How should Testagen be stored?
Store at −20 °C, sealed, dry and protected from light. Allow vial to reach room temperature before opening.
