Testagen

Testagen is a Testicular Peptide Bioregulator supplied for laboratory research. Gonadal bioregulator studied in vitro for testicular cell function pathway modeling and testosterone biosynthesis signaling mechanism research.

Testagen (Lys-Glu-Asp) is a peptide bioregulator based on testicular and gonadal tissue, studied for testicular cell function and testosterone-biosynthesis signaling.

Testagen is produced synthetically, not extracted from tissue. Its sequence (Lys-Glu-Asp) is based on a regulatory peptide associated with testicular tissue, and it is studied for gonadal cell signaling.

Testagen is supplied as a lyophilized (freeze-dried) powder — a dehydrated form that keeps the peptide stable during shipping and storage. In the laboratory it is reconstituted (returned to liquid form) using a solvent such as bacteriostatic water, added slowly against the side of the vial, which is then swirled gently — never shaken — until the powder fully dissolves. All handling is for in vitro research use only.

Store the lyophilized Testagen powder at -20°C, protected from light and moisture, where it remains stable long-term. Once reconstituted, keep it refrigerated (2-8°C) and use it within the timeframe appropriate for your research protocol.

Every batch of Testagen is produced to a purity of 99% or higher. Purity and molecular identity are verified using standard analytical methods — high-performance liquid chromatography (HPLC) to measure purity, and mass spectrometry (MS) to confirm the peptide's molecular weight.
