An 'anti-aging' tetrapeptide researched almost entirely by one group.
What it is
A synthetic four-amino-acid peptide (Ala-Glu-Asp-Gly) modelled on epithalamin, an extract of the pineal gland.
How it's thought to work
It is claimed to activate telomerase, the enzyme that maintains the protective ends of chromosomes.
What the evidence shows
Most research comes from a single research group in Russia: cell and animal studies plus small human studies. There are no large, independent randomised trials.
Regulatory status
Not approved for any use.
Safety notes
