[Investigation of antihypoxic properties of short peptides].
Kozina. L S LS
Key Findings
- Short regulatory peptides (vilon, epitalon, vesugen, pinealon) reduced damage from hypobaric hypoxia in animal models.
- Pinealon (Glu-Asp-Arg) had the strongest antihypoxic effect, likely by enhancing internal antioxidant enzymes and reducing NMDA‑mediated excitotoxicity.
- Epitalon also showed antihypoxic activity, but its effect was less pronounced than pinealon.
Practical Outcomes
- For biohackers, the data suggest epitalon might modestly improve tolerance to low‑oxygen conditions, but the study provides no human dosing or protocol details. Until more research confirms these effects in people, epitalon should be considered experimental for hypoxia resistance rather than a proven supplement.
Summary
The study found that a few short peptides, including epitalon, can help protect cells from low‑oxygen stress in animal experiments. Pinealon worked best, while epitalon showed a modest protective effect. The benefit seems to come from boosting the body's own antioxidant enzymes rather than just blocking harmful oxygen‑free radicals.
Abstract
The data presented suggest that short regulatory peptides (vilon, epitalon, vesugen and pinealon) have manifested the antihypoxic properties in the model of hypobaric hypoxia. Pinealon (Glu-Asp-Arg) has the most pronounced effect among them. The capability of pinealon to increase the neuronal resistance to hypoxic stress in experiments with prenatal hypoxia has a complex nature. It is based not so much on the inhibition of ROS increase in cells in response to stress as on stimulation of internal antioxidative enzyme system and possibly limiting the excitotoxic effect of N-methyl-D-aspartate.
