Product Information
Epithalon is a short-chain synthetic peptide composed of four amino acids, designed to interact with biological pathways associated with aging and cellular regulation. One of its most studied roles is its potential to support the activation of telomerase, an enzyme responsible for maintaining the length of telomeres. Telomeres act as protective caps at the ends of chromosomes, and their gradual shortening is widely associated with cellular aging.
In addition to its effects on telomere biology, Epithalon is linked to the regulation of the pineal gland, a key structure involved in circadian rhythm control. By supporting natural melatonin production, it may help promote more balanced sleep-wake cycles and improve sleep quality over time.
Epithalon is also associated with antioxidant activity, helping the body manage oxidative stress, which can contribute to cellular damage. Through these combined mechanisms—cellular protection, circadian support, and telomere maintenance—Epithalon is commonly used in longevity and wellness protocols aimed at sustaining overall biological function.

Anti-Aging & Cellular Longevity
Epithalon is commonly associated with supporting long-term cellular health through its interaction with telomerase activity. By helping maintain telomere length, it may contribute to slowing down visible and internal signs of aging, while supporting sustained cellular performance over time.
Sleep Quality & Circadian Rhythm Balance
One of the standout benefits of Epithalon is its potential to support natural melatonin production. This can help regulate circadian rhythms, making it easier to fall asleep, stay asleep, and experience deeper, more restorative sleep cycles, especially beneficial for individuals with disrupted sleep patterns.
Immune Defense & Skin Health
Epithalon may play a role in supporting immune system balance by promoting more efficient cellular communication and response. A well-functioning immune system is essential for protecting the body against everyday stressors and maintaining overall health.

Common Questions
Frequently Asked Questions
What is Epithalon and why is it supplied in a 50mg vial? +
Epithalon (Ala-Glu-Asp-Gly) is a synthetic tetrapeptide bioregulator studied for its role in telomerase activation and circadian rhythm regulation in longevity research. The 50mg vial size reflects the larger quantities typically used in extended anti-aging research protocols.
How much BAC water should I add to a 50mg Epithalon vial? +
A common reconstitution for a 50mg vial is 5–10 mL of bacteriostatic water. Adding 5 mL gives 10 mg/mL (10,000 mcg/mL). At this concentration, a 100 mcg dose = 1 unit on a U-100 syringe. Use the calculator on this page for precise units at your target dose.
How many doses does a 50mg Epithalon vial provide? +
With 5 mL BAC water (10 mg/mL), a 50mg vial provides approximately 500 doses at 100 mcg, or 250 doses at 200 mcg per dose. The large vial size is well suited for research protocols that run over several weeks or months.
Is Epithalon the same as Epitalon? +
Yes, Epithalon and Epitalon are the same compound (Ala-Glu-Asp-Gly, tetrapeptide-11). The name variation is a transliteration difference from the original Russian research. Both refer to the identical 4-amino-acid sequence with CAS number 307297-39-8.
Can Epithalon be combined with other anti-aging peptides in research? +
Yes, Epithalon is frequently studied alongside other bioregulator peptides such as Thymalin (immune support) and Pinealon (neurological support) in longevity research models. These combinations are a key area of ongoing research in the anti-aging peptide field.
