Testagen is the tetrapeptide Lys-Glu-Asp-Gly, studied in research on endocrine tissue models, frequently alongside the related peptide Ala-Glu-Asp-Gly.
Experimental work examines thymus and thyroid morphology and hormonal activity in hypophysectomized animals.
Third-party tested for purity, ID, quantity.
Testagen is among the short peptides that appear in paired-comparison studies with Epitalon. Published work has examined the effects of Lys-Glu-Asp-Gly and Ala-Glu-Asp-Gly on thymus morphology, on thyroid structure and hormonal activity in hypophysectomized young and old animals, and on immunity and hemostasis endpoints.
The sequence also appears in reviews of peptide-regulated cell differentiation, where KEDG is associated with immune-cell differentiation models.
Testagen was characterized within the Russian peptide-bioregulator programme as one of a family of tetrapeptides differing by a single residue.
Much of the published work deliberately compares it against Epitalon, which isolates the contribution of the N-terminal lysine.
Research into the KEDG sequence focuses on endocrine and immune tissue endpoints in hypophysectomized animal models, usually in direct comparison with Ala-Glu-Asp-Gly. Frameworks evaluate thymus and thyroid morphology, hormonal activity, and differentiation signaling.
No. Eppix Labs products are supplied exclusively for laboratory research. We do not provide dosing, administration, or usage guidance.
Each unit contains the labeled quantity of Testagen. Independent third-party analysis verifies purity, identity, and net content per batch.
The unit contains only the research compound. Any laboratory materials required for reconstitution or experimental procedures must be sourced separately.
Duration depends entirely on research design, storage conditions, and laboratory protocol.
