Epitalon is a 4-amino-acid Russian-research peptide popular in longevity stacks. It is one of the easiest peptides to synthesise and one of the most under-filled in the Australian market.
Tetrapeptide (telomerase research)
Also known as: Epithalon / AEDG
Why test Epitalon?
Epitalon's short sequence means HPLC purity is rarely the problem - under-fill is. Quantitative HPLC catches vials labelled 10 mg that contain 2-4 mg of actual peptide.
Common issues we find
Massive under-fill (often 20-40% of label)
Substitution with cheaper tetrapeptides
Mannitol-only vials
Frequently asked questions
How is Epitalon tested?
LC-MS identity, HPLC purity, and quantitative HPLC for mg per vial. A$549 per vial at LabDoc.
Is Epitalon hard to synthesise?
No - it is a 4-amino-acid peptide which is among the cheapest to manufacture. This is why vendors compete on per-vial price by under-filling rather than by using cheaper raw material.
