Testagen 20mg COA and lot verification

Each Testagen 20mg lot ships with a third-party Certificate of Analysis that lists the lot identifier, the reversed-phase HPLC purity result and the mass-spectrometry identity confirmation for that batch. Match the lot number printed on the vial to the lot on the COA before the material is used in any in-vitro protocol; if the two do not match, contact us for the correct document.

What is Testagen 20mg?

Testagen is a 4-amino-acid synthetic peptide (Lys-Glu-Asp-Gly) derived from the Khavinson short-peptide line of organ-specific bioregulators. It is the prostate/urogenital-tissue counterpart to other Khavinson tetrapeptides such as Epitalon (pineal) and Bronchogen (lung).

Why researchers buy Testagen from Amino Fuel Labs

  • Testagen is catalogued in 20mg, listed from $65.00 per vial, so the exact strength and current price are visible before checkout.
  • Review the linked Testagen certificate of analysis for the reported analytical results and lot identifier.
  • Specifications are published on the page rather than on request: Testagen is supplied as lyophilized powder and stored at 2–8°C (Refrigerator).

Testagen 20mg FAQ

What is Testagen studied for?

Testagen appears in laboratory research covering male hormonal research, testicular function studies, andrology. Every reference describes in-vitro or preclinical study models, not outcomes in people.

Does Testagen include a Certificate of Analysis?

Yes. Each Testagen lot ships with a batch-specific third-party Certificate of Analysis reporting 99.3% purity by reversed-phase HPLC with mass-spectrometry identity confirmation. The COA linked on this page matches the lot number printed on the vial.

What form does Testagen arrive in and how is it stored?

Testagen is supplied as lyophilized powder in a sealed vial with its lot documentation. Store at 2–8°C (Refrigerator), protect the vial from light and avoid repeated freeze–thaw cycles.

Does HPLC purity tell me the net peptide content?

No. HPLC area-percent purity and net peptide content are different measurements. Review the report for each value rather than treating them as interchangeable. Read about peptide purity versus net content.

What tissue does Testagen target?

In published Khavinson-group research, Testagen is the prostate/urogenital-tissue bioregulator of the short-peptide family — analogous to how Epitalon targets the pineal gland and Bronchogen targets bronchial epithelium.

Is Testagen androgenic?

No. Testagen is a 4-amino-acid peptide that modulates gene expression in prostate and urogenital tissue, rather than acting as an exogenous androgen. It is studied for tissue-specific regulatory effects, not steroid replacement.

Is your Testagen third-party tested?

Yes — every batch ships with HPLC verification at 99.3% purity, mass-spec identity confirmation and a batch-specific Certificate of Analysis.

How does Testagen differ from the other bioregulator peptides listed?

Testagen is a separate short peptide with its own sequence, vial size and lot documentation. Each bioregulator listing is tested and released independently, so review the Certificate of Analysis for the specific material you intend to study.
