Testagen 20mg (Bioregulator) Overview

Testagen 20mg from Peptide Science is the synthetic Khavinson short-peptide bioregulator derived from testicular tissue fractions, supplied as a lyophilised vial for in-vitro and preclinical testicular-cell and reproductive-research applications.

Khavinson Short-Peptide Class Background

Testagen 20mg (Bioregulator) belongs to the Khavinson short-peptide family, a class of synthetic two-to-four-residue peptides originally derived from bioregulator-fraction extracts of mammalian tissues by V. Kh. Khavinson and colleagues from the 1980s onward. The class is characterised by short sequence length (typically 2 to 4 amino acids), organ-specific source-tissue derivation, and synthetic reconstitution of the original tissue-fraction activity. The full class includes Epithalon (pineal), Cortexin (cerebral cortex), Pinealon (pineal), Vesugen (vascular), and the dozen organ-specific bioregulators in this catalogue.

Testicular Bioregulator Research Context

Testagen is studied in preclinical research for testicular-cell signalling pathways and reproductive-system research models. The compound is the testicular-targeted member of the Khavinson family and pairs with Prostamax for male-urogenital-system comparative research protocols.

Reconstitution and Handling

The lyophilised short peptide reconstitutes with bacteriostatic water at the working concentration set by the principal investigator. Aliquoting reconstituted stock for single-use frozen storage is the standard handling practice cited in Khavinson-tradition research protocols.
