Pinealon vs epitalon (epithalon): evidence compared

Which is better, Pinealon or epitalon?

Epitalon has the larger and more varied evidence base (human cell, lifelong mouse, and observational human reports) and a regulatory path in progress: FDA removed it from Category 2 in April 2026 and its advisory committee recommended it for the 503A bulks list in July 2026. Pinealon has only rat and cell work from its developers and has never been nominated for compounding. The edge is relative: both are graded animal-only, neither is proven to help people, and epitalon still has no lawful compounded supply until FDA publishes a final rule. [1] [5] [6] [7] [9] [10]

How do Pinealon and epitalon compare?

Pinealon and Epitalon compared by dimension
Dimension	Pinealon	EpitalonFavored
Structure [3] [5]	Tripeptide Glu-Asp-Arg (EDR), a Khavinson short peptide bioregulator.	Tetrapeptide Ala-Glu-Asp-Gly (AEDG), a synthetic version of the bovine pineal extract Epithalamin.
Proposed mechanism [2] [3] [5] [8]	Limits reactive oxygen species and necrotic death in neurons and other cells under oxidative stress; developers propose it also acts on gene expression linked to Alzheimer's disease.	Induces telomerase and lengthens telomeres in human cell cultures, through telomerase upregulation or the alternative lengthening pathway depending on the cell line.
Animal evidence [1] [6]	Rats with prenatal hyperhomocysteinemia: offspring of treated mothers had better spatial learning and fewer necrotic cerebellar neurons.	Lifelong study in female mice: some aging biomarkers slowed, the longest lived 10% lived longer, and spontaneous tumors fell, but mean life span did not change significantly.
Human evidence [4] [7]	No controlled human trial. A Russian language review from the developers describes use of peptide bioregulators in people of various ages without trial detail.	No randomized trial. Open, non-randomized follow up of elderly patients over 6 to 12 years, mostly with the pineal extract Epithalamin, reported lower mortality than untreated controls.
Independent replication [1] [2] [3] [8]	No independent replication identified; the studies cited here all come from the developing group.	An independent UK laboratory reported telomere lengthening in human cell lines in 2025; no independent animal or human outcome study.
FDA and compounding status [9] [10] [11] [12]	Never nominated for the 503A or 503B bulks lists and not an approved drug, so a 503A pharmacy has no lawful basis to compound it.	Removed from 503A Category 2 in April 2026 and recommended for the 503A bulks list by the advisory committee in July 2026; not lawful to compound from bulk until FDA publishes a final rule.
Dosing [4] [7]	No human dose established; supplement labeling in Russia is not based on a dose finding study.	No human dose established; no human pharmacokinetic or dose ranging study has been published.
Safety [1] [6]	No human safety data of any kind.	No systematic human safety data; telomerase activation raises a theoretical question about existing tumors, although the mouse study found fewer tumors.
WADA status [13]	Prohibited at all times under section S0 (non-approved substances).	Prohibited at all times under section S0 (non-approved substances).
Typical cost [10] [12]	No lawful price. Not available through licensed US channels; research chemical listings are not lawful for human use.	No lawful compounded price until FDA publishes a final rule; advertised clinic prices are not a comparable price.

Evidence grade and regulatory status

Pulled from each peptide’s own record, so it stays in step with the peptide pages.

Pinealon and Epitalon: grade, status, and cost
Attribute	Pinealon	Epitalon
Class	Synthetic tripeptide (Glu-Asp-Arg) from the Khavinson family of short peptide bioregulators	Synthetic tetrapeptide (Ala-Glu-Asp-Gly) modeled on the bovine pineal extract Epithalamin
What it is	Three amino acid peptide from Russia's Khavinson bioregulator family, sold there as a brain supplement; rat and cell data only, no controlled human trial.	4 amino acid peptide from a pineal gland extract: telomere and lifespan data in cells and mice, small non-randomized Russian human reports, not FDA approved.
Evidence	Evidence: Animal-only evidence	Evidence: Animal-only evidence
FDA status	Regulatory: Unscheduled	Regulatory: Under FDA review
Compounding	Pinealon has never been nominated to or reviewed for the FDA 503A or 503B bulks lists and does not appear on the FDA Category 2 page (current as of April 22, 2026). It is not a component of any approved drug, so a 503A pharmacy has no lawful basis to compound it. It is not an FDA approved drug and is sold in Russia only as a supplement, not a medicine.	Epitalon was placed on the FDA 503A Category 2 list (substances with significant safety risks) in 2023 and removed from it on April 15, 2026. On July 23 to 24, 2026 the Pharmacy Compounding Advisory Committee recommended adding epitalon to the 503A bulks list. As of the last verification date FDA has not published a final rule, so compounding pharmacies and state boards vary in whether they will fill it. It is not an FDA approved drug and is not eligible for 503B outsourcing.
WADA	WADA: WADA prohibited	WADA: WADA prohibited
Routes	Oral capsule (sold as a supplement in Russia), Subcutaneous or intranasal use described by sellers (no studies), Injection (rat studies)	Subcutaneous injection (as sold), Intramuscular injection (Russian Epithalamin reports), Intranasal and oral products exist without absorption data
Typical cost	Not available through licensed US channels. Products sold as research chemicals are not lawful for human use and are not verified for identity or purity.	No lawful compounded price: Epitalon is not on the 503A bulks list, and PCAC's July 2026 recommendation is advisory until FDA publishes a final rule. Advertised clinic prices are not a comparable price. Products sold as research chemicals are not lawful for human use and are not verified for identity or purity.

Has Pinealon been tested directly against epitalon?

No published trial has compared Pinealon and epitalon directly. The dimensions above come from separate studies and labels, and cross-trial comparisons are less reliable than a direct trial.

What do Pinealon and epitalon cost?

Typical cost of Pinealon and Epitalon
Dimension	Pinealon	Epitalon
Typical cost	Not available through licensed US channels. Products sold as research chemicals are not lawful for human use and are not verified for identity or purity.

Price detail	Price index in progress	Epitalon price by channel

Where a price index exists, the range is the cash price per month across branded, compounded, and telehealth channels, without insurance. The cost pages give each channel separately with its sources. Otherwise the typical cost from the peptide record is shown. Legal access depends on your state: see peptide legality by state.

Frequently asked questions

Are pinealon and epitalon the same thing?

No. Both are short synthetic peptides from the same St. Petersburg research group, but pinealon is three amino acids (Glu-Asp-Arg) aimed at the brain, and epitalon is four (Ala-Glu-Asp-Gly) modeled on a pineal gland extract and aimed at aging. [3] [5]

Which has better evidence?

Epitalon, though neither is strong. Epitalon has human cell studies, a lifelong mouse study, and non-randomized human reports. Pinealon has rat and cell studies only. Neither has a randomized human trial. [1] [2] [5] [6] [7]

Does epitalon lengthen telomeres in people?

That has not been shown. Telomerase activation and telomere lengthening were measured in cultured human cells, not in people, and no human trial has measured telomere length after epitalon. [5] [8]

Can either be prescribed legally in the US?

Not yet. Epitalon was recommended for the 503A bulks list in July 2026, but a pharmacy has no federal basis to compound it from bulk until FDA publishes a final rule. Pinealon has never been nominated and has no lawful path. [9] [10] [11]

Are they allowed in sport?

No. Both are unapproved substances prohibited at all times under WADA section S0. [13]
