How does Epitalon work?
Tetrapeptide derived from the larger pineal hormone epithalamin. Proposed mechanism is telomerase activation and circadian / pineal modulation. Russian preclinical and limited human data. In plain terms, Epitalon is studied as an anti-aging and sleep-cycle peptide. A tetrapeptide derived from epithalamin, looked at for telomerase activation and circadian / pineal support, with limited human data. Mechanistic detail like this comes largely from preclinical and early research, the human picture is limited.
What people use it for
- Users running longevity-focused stacks
- People with disrupted circadian rhythm or sleep architecture
- Older adults experimenting with anti-aging protocols
