At present, there is no clinically established or evidence-based way to use pineal gland

Peptides
— A family of substances whose molecules are built from two or more amino acids. Peptides encompass around half of all known hormones and the majority of enzymes.

for anti-aging in humans. Existing research remains largely experimental and confined to preclinical models and small, geographically limited human studies. Interest in these compounds stems from the broader category of bioregulator peptides. They are short chains of amino acids investigated for their potential roles in cellular signaling and tissue regulation.
Within this context, peptide preparations derived from pineal tissue have been explored as hypothetical modulators of age-related physiological changes, largely based on mechanistic reasoning and early clinical observations. Understanding what is known and where the scientific gaps remain provides a necessary foundation for evaluating both the promise and the limitations of pineal gland peptides for anti-aging purposes.
What is the Pineal Gland?
The pineal gland (corpus pineale, epiphysis cerebri) is a small endocrine organ located deep within the brain. It plays a central role in
chronobiology
Chronobiology
— The study of biological rhythms and how they affect living organisms, including how our bodies respond to the time of day and seasonal changes.

through its secretion of melatonin, a hormone that synchronizes circadian and seasonal biological rhythms.
The gland has been anatomically described for more than 2,000 years, with historical interpretations ranging from mythological significance to modern neuroendocrinology. Its pinecone-like shape gives rise to its name.
Where is the Pineal Gland Located?
The pineal gland is located in the epi
thalamus

— Relay center for sensory and motor signals.

, near the center of the brain, between the two hemispheres in a groove formed by the thalamus. It grows until early childhood, remains relatively stable through adolescence, and often undergoes calcification in adulthood. Adult pineal gland mass typically ranges between 100 and 150 mg.
What Does the Pineal Gland Do?
The primary and well-established endocrine function of the pineal gland is the synthesis and secretion of melatonin, the so-called hormone of youth. The pineal gland also participates indirectly in
serotonin

('the hormone of happiness'), as serotonin serves as a biochemical precursor to melatonin.
These functions of the pineal gland theoretically suggest that it can play a certain role in life expectancy and

. But even though the age-related reductions in melatonin secretion are well documented, there is no conclusive evidence that pineal gland aging causally determines human lifespan or that restoring pineal function extends longevity.
How to Activate the Pineal Gland?
The functions of the pineal gland can be activated via healthy nutrition and/or supplement intake, among other ways. One example of supplements is pineal gland–derived peptides, which are included in the group of
peptide bioregulators
Peptide Bioregulators
— Short chains of amino acids extracted from animal organs and tissues or synthesized, belonging to the class of biologically active substances in pharmacology. They work by interacting with cellular receptors, enzymes, and other molecules to regulate various physiological processes. Bioregulators can help to optimize cellular metabolism, repair damaged tissues, enhance organ function, and support overall health and well-being.

Peptide Bioregulators and Biological Signaling
Peptide bioregulators, or dietary peptides, were extensively studied in the late Soviet and post-Soviet scientific context, particularly by Professor Vladimir Khavinson. His hypothesis proposed that short peptides derived from specific organs could influence gene expression and cellular function in corresponding tissues.
Several small clinical studies conducted in elderly populations reported changes in biomarkers and mortality rates following peptide administration. However, these studies were limited by small sample sizes, inconsistent use of placebo controls, and lack of independent replication. As a result, Khavinson peptides are not incorporated into international clinical guidelines and remain experimental.
Safety, Cost, and Clinical Oversight
Short-term studies of certain peptide preparations report acceptable tolerability. However, long-term safety data, pharmacovigilance systems, and standardized dosing protocols are lacking. Statements that such peptides have “no side effects” are not scientifically substantiated.
Given their experimental status, peptide-based interventions should not be used without medical supervision, particularly by individuals with endocrine disorders, cancer histories, or those taking hormone-modulating medications.
Summary
Pineal gland peptides remain an experimental area of biomedical research, supported primarily by preclinical studies and small human trials conducted within limited geographic contexts. While melatonin, which is the pineal gland’s primary hormone, has a well-established role in circadian regulation and emerging therapeutic applications, claims that pineal peptides slow aging, extend lifespan, or prevent disease are not supported by high-quality evidence.
Substantial, independent, large-scale clinical trials are required before pineal peptide interventions can be considered safe or effective for human health optimization or anti-aging purposes.
