These peptides are freeze-dried, a process that helps support shelf life while preserving the purity and integrity of the peptides during storage.
Every product is supported by batch-specific documentation so researchers can review purity, identity, and quality information before use.
Our research peptide products are offered in a 99%+ research-grade purity format and are tested to confirm quality, identity, and consistency.

Research
Testagen (KEDG) is a tetrapeptide first classified among Khavinson peptides that may directly interact with nuclear DNA and histones :contentReference[oaicite:1]{index=1}.
- Thyroid & Pituitary Modulation: In hypophysectomized avian models, Testagen normalized TSH, T3/T4, thyroid structure, and increased pituitary-driven hormone release :contentReference[oaicite:2]{index=2}.
- Testosterone & Hormonal Balance: Research indicates stimulation of estrogen/testosterone regulation via pituitary modulation, especially under low-androgen conditions :contentReference[oaicite:3]{index=3}.
- Immune & Hemostatic Effects: Avian studies showed improved immune parameters and normalized coagulation profiles following Testagen administration :contentReference[oaicite:4]{index=4}.
- Epigenetic Activity: Peptide exhibits binding to histones and DNA, potentially influencing cellular differentiation and gene expression processes :contentReference[oaicite:5]{index=5}.
Preclinical evidence only – human applications not evaluated.
