Peptides for Anti-Aging Research

2 research peptides are currently studied for anti-aging research. This guide ranks them by evidence strength and covers their mechanisms, safety profiles, and current clinical status.

Pinealon (Glu-Asp-Arg, EDR) is a synthetic tripeptide with a molecular weight of approximately 418 g/mol, developed by Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology. This compound is classified as a bioregulatory peptide, primarily targeting the brain and pineal gland functions. Research is predominantly limited to preclinical studies and small-scale open-label clinical observations conducted in Russia, lacking rigorous controlled trials published in peer-reviewed international journals. Notably, studies suggest that Pinealon may exhibit neuroprotective properties in cell culture models and potentially enhance melatonin production, which could have implications for sleep regulation and circadian rhythms. However, the absence of larger, controlled studies raises questions about the reproducibility and generalizability of these findings, warranting caution in interpreting its potential benefits.

Cortagen (Ala-Glu-Asp-Leu, AEDL) is a synthetic tetrapeptide with a molecular weight of around 446 g/mol, also developed by Vladimir Khavinson as a bioregulatory peptide aimed at modulating functions within the cerebral cortex. Similar to Pinealon, the evidence supporting Cortagen is primarily derived from Russian preclinical studies and small, uncontrolled clinical observations, with no independent replications or controlled trials documented in the broader scientific literature. Preliminary findings indicate that Cortagen may confer neuroprotective effects in ischemia models and has been suggested to normalize gene expression in cortical tissue. While these claims are intriguing, the limited scope and methodological rigor of existing studies highlight the need for further investigation to validate these effects and understand their implications for anti-aging therapies.
