What is Bacteriostatic Water and what is Epitalon?
Bacteriostatic Water is classified as Sterile preserved laboratory diluent; Epitalon as Synthetic tetrapeptide. Both profiles below cover scientific identity only — what the molecule is and which laboratory models it appears in. Verve supplies both strictly as in-vitro reference materials, and neither profile describes human or veterinary use.
Bacteriostatic Water
Sterile preserved laboratory diluent
Bacteriostatic water is not a peptide but a laboratory reagent: sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. The benzyl alcohol inhibits the growth of common contaminating organisms, which allows a sealed vial to be accessed more than once over the course of a study without the reagent itself becoming a source of microbial contamination.
full Bacteriostatic Water profile →Epitalon
Synthetic tetrapeptide
Epitalon is a synthetic tetrapeptide with the sequence alanyl-glutamyl-aspartyl-glycine (Ala-Glu-Asp-Gly), developed as a short synthetic analog of a peptide fraction isolated from the pineal gland. It is a small, water-soluble peptide and one of the most frequently cited reference compounds in pineal-peptide and cellular-aging research literature.
