Epitalon

Epitalon is a chain of four amino acids ^[6]. Amino acids are the building blocks of proteins. It is made in a lab. Its design was based on an extract from the pineal gland of cattle ^[6]. The pineal gland is a small gland in the brain. It makes melatonin, a hormone that helps control sleep ^[6]. FDA treats Epitalon and that extract, called epithalamin, as different substances ^[6].

Epitalon is part of no FDA-approved drug and has no official quality standard ^[6]. It is sold as a free base and as an acetate salt, and FDA treats them as two different substances ^[6]. Websites and clinics promote it for slower aging, longer life, better sleep and many other uses ^[6]. It once had an orphan drug designation for an inherited eye disease. That designation was withdrawn in 2016, and it was never an approval ^[6].

Epitalon is in limbo: FDA lists it among the Category 2 substances whose nominations were withdrawn, and it has not added it to Category 1 ^{[1] [2]}. That is not approval, and it does not make compounding lawful. FDA's meeting notice lists insomnia as the one use it reviewed, but websites sell Epitalon mostly for slower aging and longer life ^{[4] [6]}. Checked 23 October 2026.

Category 2 is FDA's list of substances that may present significant safety risks. Category 1 is the list of substances pharmacies may use while FDA reviews them ^[3]. The groups that nominated Epitalon withdrew their nominations, so it came off Category 2 ^{[1] [6]}. FDA then reviewed it on its own. FDA's scientists found no study of its safety in people and advised against adding it to the list ^{[6] [8]}. FDA did not review the other uses named in the nominations, such as anti-aging ^[6].

On 24 July 2026, FDA's Pharmacy Compounding Advisory Committee met on Epitalon ^{[4] [5] [7]}. One legal report says the committee voted 7 to 4, with 1 member abstaining, to recommend adding it to the list ^[11]. News and other legal reports also name Epitalon among the peptides the committee backed ^{[12] [13] [21]}. FDA's meeting page does not show the vote ^[5]. A committee vote is only advice ^[11]. FDA decides by writing a rule, after public comment ^{[11] [22]}.

Until then, a pharmacy that makes Epitalon is outside federal law ^{[3] [11]}. In 2020, a Kentucky compounding pharmacy pleaded guilty to distributing unapproved new drugs, Epitalon among them ^[10]. Selling Epitalon for people to use is also illegal, even when the label says it is for research only ^{[9] [13]}.

The evidence grade is animal-only: the studies that show an effect on health used mice or cells, and no study has tested whether Epitalon helps people sleep or age better ^[6]. Most Epitalon studies, including the few in people, come from one research group in Russia ^{[6] [15]}.

People: in a small study, 20 women aged 40 to 50 who worked night shifts took Epitalon under the tongue for 20 days ^{[6] [14]}. A melatonin marker in their urine rose, while it did not change with a placebo ^{[6] [14]}. The study did not measure sleep and did not report safety. Its full report is in Russian ^{[6] [14]}. FDA says a change in melatonin means little without a change in health ^[6].

Melatonin falls with age, and websites say Epitalon restores it ^{[6] [15]}. A level that falls with age is not evidence that taking Epitalon helps. Low melatonin has not been clearly linked to insomnia in older adults ^[6].

Animals: female mice got Epitalon shots under the skin for a few days each month. It did not change their average life span. The longest-lived mice lived a little longer, and one blood cancer was less common ^[16]. In mice bred to get breast tumors, treated mice had fewer and smaller tumors ^[17]. In old female monkeys, it raised evening melatonin, but nobody measured their sleep ^[6]. In rat pineal glands kept alive in a lab device, it did not raise melatonin ^[18].

Cells: in human fetal cells in a lab dish, Epitalon switched on telomerase and lengthened telomeres ^[19]. Telomeres are caps on the ends of chromosomes that shorten as cells age. A 2025 lab study by a London group found the same in human cell lines, including breast cancer cells ^[20]. FDA says this same effect raises a cancer concern ^[6].

There is no legal way to get Epitalon in the US today ^[6]. No approved drug contains it. No product with it is approved in Europe, Canada, Australia or the UK ^[6]. A pharmacy may use a substance with no official quality standard only if it is in an approved drug or on the federal list. Epitalon is neither ^{[3] [6]}. That could change if FDA adds it by writing a rule after the committee vote ^{[11] [13]}.

FDA found no clinical study of Epitalon's safety in people ^[6]. One study in the US registry includes Epitalon in a skin serum, but only invited people can join, so it is not an open trial ^[23]. Any open trial that gives Epitalon would appear in the trials block below, with the date the official registry was last checked. FDA notes that approved drugs for insomnia already exist ^[6].

People who use Epitalon get it in three main ways ^[6]. The first is websites that sell it as vials, capsules or a mouth spray ^[6]. Several of these sites say the product is for research use only ^[6]. FDA says that label does not make it legal to sell a drug meant for people ^{[9] [12]}. The second is pharmacies. Some clinics say they get Epitalon from a compounding pharmacy, though FDA could not find one that makes it ^[6]. In 2020, one compounding pharmacy pleaded guilty to selling it and other unapproved drugs ^[10]. The third is clinics. Wellness clinics and concierge doctors promote it for anti-aging ^{[6] [8]}.

In all three, nobody checks what is in the product the way FDA checks an approved drug. FDA found no test results for clumps or germ toxins in Epitalon powder offered for shots ^[6]. FDA found no reports of harm from Epitalon in its files. FDA says that does not show it is free of harm, because reporting is voluntary and pharmacies seldom report ^{[6] [8]}.
