Epithalon
Also known as: Epitalon
A lab-made peptide based on a natural compound from the pineal gland (a small gland in your brain). It's studied for its ability to activate telomerase, the enzyme that keeps the protective caps on the ends of your chromosomes from shortening. Since those caps naturally shorten as cells age, this peptide is one of the most talked-about in anti-aging research. Originally developed in Russia.
Epithalon (also spelled Epitalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed by the Russian gerontologist Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology. It is based on the natural peptide epithalamin produced by the pineal gland, and is the most studied peptide in the telomere-maintenance category of anti-aging research.
Epithalon's primary mechanism is activation of telomerase, the enzyme responsible for maintaining telomere length at chromosome ends. Telomere shortening is one of the recognized hallmarks of aging — as telomeres erode with each cell division, cells eventually enter senescence and stop functioning. By activating telomerase, Epithalon theoretically extends cellular lifespan and delays the onset of senescence. Animal studies have shown lifespan extension in several species.
Epithalon also stimulates melatonin production by the pineal gland, which declines significantly with age. This secondary effect may explain the improved sleep quality commonly reported during treatment courses. Typical protocols use 5-10 mg subcutaneously daily for 10-20 day courses, repeated 2-3 times per year. The main theoretical concern is that telomerase activation could promote pre-cancerous cells, since cancer cells often exploit telomerase to achieve immortality.

Mechanism of Action
Epithalon (also spelled Epitalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) based on epithalamin, a peptide extract from the pineal gland first studied by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology. Its primary reported mechanism is the activation of telomerase — the ribonucleoprotein enzyme complex responsible for maintaining telomere length at chromosome ends.
Telomeres are repetitive nucleotide sequences (TTAGGG in humans) that cap and protect chromosome ends from degradation, fusion, and recognition as DNA damage. With each cell division, the DNA replication machinery cannot fully copy the very end of the lagging strand (the 'end replication problem'), resulting in progressive telomere shortening. When telomeres reach a critical length, cells enter replicative senescence (permanent growth arrest) or apoptosis — a fundamental mechanism of cellular aging. Telomerase, composed of the catalytic subunit hTERT (human telomerase reverse transcriptase) and the RNA template component hTR/TERC, can add TTAGGG repeats back to chromosome ends, counteracting this shortening.
Epithalon reportedly activates the expression of the hTERT gene, increasing telomerase activity in somatic cells. In cell culture studies, epithalon treatment was associated with increased telomere length and extended replicative lifespan in human fibroblasts and retinal pigment epithelial cells. The peptide also reportedly stimulates melatonin production by the pineal gland, potentially through gene-regulatory effects on pineal cells. Melatonin itself is a potent antioxidant and circadian regulator, and its decline with age correlates with numerous age-related changes. Additional reported effects include normalization of T-cell function, modulation of neuroendocrine signaling, and improved antioxidant enzyme expression. It should be noted that the majority of published research comes from Russian institutions, and large-scale, peer-reviewed Western clinical trials are lacking.

AEDG Peptide
A tetrapeptide (Ala-Glu-Asp-Gly) identical to Epithalon's core active sequence — effectively the same compound. Studied for telomerase activation and pineal gland regulation, promoting melatonin production and potentially slowing cellular aging through telomere maintenance. Part of the Khavinson bioregulator peptide family developed in St. Petersburg.
CJC-1295 (no DAC)
One of the most popular growth hormone peptides, often called Mod GRF 1-29. Instead of injecting growth hormone directly, this tells your pituitary gland to release more of its own GH naturally. This is considered healthier than injecting GH directly because your body keeps its normal feedback systems intact. Usually combined with Ipamorelin for much stronger effects — the two work together better than either alone.
CJC-1295 + Ipamorelin
The most commonly prescribed peptide combination in anti-aging and regenerative medicine. Pairs the GHRH analogue CJC-1295 (Mod GRF 1-29) with the selective ghrelin-mimetic Ipamorelin for synergistic, pulsatile growth hormone release. Exploits two complementary signaling pathways — cAMP (GHRH) and calcium/PLC (ghrelin receptor) — to amplify GH pulses while maintaining minimal side effects.
CJC-1295 with DAC
The long-acting version of CJC-1295. After injection it attaches to a protein in your blood (albumin), which keeps it active for nearly a week instead of just 30 minutes. This means you only need to inject once a week. The trade-off is that it keeps growth hormone elevated constantly rather than in natural pulses, which some practitioners consider less ideal for your body. More convenient but potentially less natural than the no-DAC version.
