Epitalon (Ala-Glu-Asp-Gly) is a synthetic tetrapeptide studied for telomerase activation and pineal gland function — Khavinson's original research showed telomere elongation in human cell cultures. I've been following the longevity data on this compound since the early Khavinson publications. For sourcing, Bio Longevity Labs carries 20mg vials at $56.98 ($2.85/mg).

ModerateTherapeutic peptides offer mechanistically diverse approaches to targeting fundamental hallmarks of aging, a 2026 review demonstrated. While FDA-approved agents show clinical potential, investigational peptides require rigorous validation through well-designed trials to establish long-term safety and efficacy.
EmergingTherapeutic peptides, including BPC-157 and TB-500, were found to modulate molecular signaling networks influencing tissue regeneration and inflammation resolution in a 2026 review. The research highlighted their mechanistic potential for orthopaedic applications, noting a current lack of clinical trials.
EmergingEpitalon demonstrated dose-dependent telomere length extension in normal human cells through hTERT and telomerase upregulation in a 2025 in-vitro study. Researchers also found that the peptide increased telomere length in cancer cell lines primarily via Alternative Lengthening of Telomeres activation.
PreclinicalThe tetrapeptide Epitalon restored delayed wound healing in high glucose-injured human retinal cells by inhibiting epithelial-mesenchymal transition and fibrosis, a 2025 in vitro study demonstrated. Researchers found that the peptide also reduced intracellular reactive oxygen species and restored antioxidant gene expression.
PreclinicalA 2025 review found that the tetrapeptide Epitalon demonstrates geroprotective and neuroendocrine properties through antioxidant and neuroprotective mechanisms. Researchers highlighted its ability to influence melatonin synthesis, modulate interleukin-2 levels, and enhance telomerase activity in preclinical models.
PreclinicalA 2025 preclinical study demonstrated that Epitalon activates telomerase, significantly improving bovine oocyte maturation rates and post-thawed embryo development. The peptide enhanced the overall quality of in vitro mature oocytes and blastocysts by improving mitochondrial health and reducing reactive oxygen species.

Epitalon is the longevity peptide I follow primarily because of Khavinson's original work on telomerase activation — the in vitro data showing telomere elongation in human fetal fibroblast cultures was published over two decades ago and remains one of the most cited papers in peptide longevity research.
Amino Club batch EPI0001 verified at 99.710% purity via Biogenica Labs. At 390.3 Da it's a simple tetrapeptide (Ala-Glu-Asp-Gly). COA PDF linked below.
The honest assessment: epitalon has a strong in vitro evidence base and some animal data, but the clinical evidence in humans is thin — Khavinson's own human studies were small-sample observational work, not controlled trials. I track it because the telomerase mechanism is genuinely interesting, but the evidence level is below what I'd cite for compounds like semaglutide or tirzepatide.
