Product Details
1. Overview
Epitalon (Epithalon) is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly. It was originally derived from research on epithalamin, a pineal gland extract, and has been studied in laboratory settings for its effects on cellular and enzymatic parameters. Knowlux supplies Epitalon as a research-grade peptide; it is not approved by the FDA or EMA for any therapeutic use, and FDA has evaluated Epitalon-related bulk drug substances and found that the criteria weigh against inclusion on the 503A compounding list.
2. Research Context (Not a Therapeutic Claim)
Published preclinical literature describes Epitalon as a peptide that has been investigated in in vitro and in vivo research models. These descriptions are derived from published research and are provided for scientific reference only. Knowlux makes no claims regarding the efficacy, safety, or suitability of this product for any human or veterinary application. Commercial promotion of Epitalon for anti-aging, telomere extension, or sleep improvement is not supported by Knowlux and is inconsistent with research-use-only supply.
