Testagen

Testagen is a synthetic tetrapeptide, H-Lys-Glu-Asp-Gly-OH (single-letter KEDG), of L-lysine, L-glutamic acid, L-aspartic acid and glycine — a single-residue variant of Epithalon (Lys in place of the N-terminal Ala) from the St. Petersburg (Khavinson) line of short peptide bioregulators. It is listed here strictly as an analytical reference entity — it is not sold, stocked, or certified by Lineará, and has no price or certificate of analysis. The data on this page is characterization only: molecular formula C17H29N5O9 and the values computed from it. No biological activity, mechanism, or use is described or implied.

Testagen has the sequence Lys-Glu-Asp-Gly. A linear tetrapeptide, H-Lys-Glu-Asp-Gly-OH (single-letter KEDG), of L-lysine, L-glutamic acid, L-aspartic acid and glycine with free termini; it differs from Epithalon (AEDG) only at the first residue (Lys in place of the N-terminal Ala). The formula C17H29N5O9 follows from the four residues less three waters and reconciles with the sequence-derived structure (no unassigned stereocentres). Registry coverage is thin: no PubChem CID, UNII, or InChIKey is asserted here — the entity ships as ChemicalSubstance on its verified sequence and formula rather than a machine-verified key (see the identifiers report). The CAS number is provisional and single-source. A computed 3D conformer is held pending the chemist sign-off.

Testagen has the molecular formula C17H29N5O9, giving an average molecular weight of 447.44 g/mol and a computed monoisotopic mass of 447.1965 Da.

The CAS Registry Number for Testagen is 1026993-38-3.

Yes. Testagen is a peptide — a chain of amino-acid residues joined by peptide bonds, 4 residues in length. Its identity is defined by that sequence and its molecular mass.

As a research material, Testagen is typically handled as a lyophilized (freeze-dried) powder. It is kept desiccated and cold — commonly 2–8 °C for short periods and −20 °C for longer storage — and reconstituted in sterile or bacteriostatic water. This is storage and handling information only, not a use protocol.

No. Testagen is listed here only as an analytical reference entity. It is not part of the Lineará formulary, has no price or certificate of analysis, and is not offered for sale.

No. Testagen is presented strictly as characterization reference data. It is not a drug, is not approved for any human or veterinary use, and must not be administered to humans or animals.
