N-Acetyl Epitalon Amidate: Reference Overview and Reconstitution Notes

N-Acetyl Epitalon Amidate

What it is

N-Acetyl Epitalon Amidate is a chemically modified analog of Epitalon (also spelled Epithalon), a synthetic tetrapeptide with the amino acid sequence Ala-Glu-Asp-Gly (AEDG). This version carries two terminal modifications, an acetyl group added at the N-terminus and an amide group at the C-terminus, changes that are generally introduced to peptides to reduce recognition by exopeptidase enzymes and to influence stability in experimental systems.

Research context and categorization

N-Acetyl Epitalon Amidate is grouped under the Khavinson bioregulator category and, more specifically, among the anti-aging and longevity peptides. The parent Epitalon sequence was developed by Vladimir Khavinson's group at the St. Petersburg Institute of Bioregulation and Gerontology as a synthetic analog of epithalamin, a peptide fraction originally associated with the pineal gland.

In neutral research terms, the Epitalon family is most often discussed in relation to telomere biology and pineal-axis signaling. It has been investigated in laboratory and animal-model settings in the context of telomerase (hTERT) expression, the replicative capacity of cultured cells, circadian and melatonin rhythms tied to pineal function, and general markers of cellular aging. The bioregulator hypothesis behind the series is that very short peptides may act as tissue-associated regulators of gene expression, and Epitalon is the compound most commonly cited in that longevity-focused discussion. The N-acetyl and amidate modifications are studied mainly for their effect on peptide stability and enzymatic resistance rather than representing a separately validated mechanism.

These uses are investigational. The compound is examined chiefly in preclinical, laboratory, and animal contexts, much of it in Russian-language gerontology literature, and the effects described there are not confirmed, established, or approved outcomes in humans.

Status

Regulatory status: Research-only, not FDA-approved. Neither Epitalon nor this modified analog is approved by the FDA or other major regulators for any indication, and there are no completed pivotal human trials establishing safety or efficacy.
Sport status: Not specifically listed on the WADA Prohibited List by name. Epitalon and its analogs are commonly discussed as falling under the S0 (Non-Approved Substances) catch-all, which covers pharmacological substances with no current regulatory approval for human therapeutic use. An athlete should treat an unapproved research peptide as potentially caught by that broad provision rather than assume it is permitted.

Reconstitution notes (general)

Lyophilized peptides are prepared by adding bacteriostatic water to the freeze-dried powder. The working concentration equals the milligrams of peptide in the vial divided by the millilitres of bacteriostatic water added. For example, the same amount of powder in a smaller volume yields a higher concentration, while a larger volume yields a lower one. A reconstitution calculator is available at our reconstitution and blend calculators to work out the volume for a target concentration.

Dilution and handling notes (compound-specific)

N-Acetyl Epitalon Amidate is supplied as a lyophilized powder for reconstitution, commonly in vials of around 5 mg to 20 mg. Bacteriostatic water is the usual diluent, since its benzyl alcohol preservative allows multiple withdrawals over a refrigerated working window. If you happen to be working with a non-lyophilized presentation, it is not reconstituted and these mixing steps do not apply.

As a very short, hydrophilic tetrapeptide, this compound is among the more water-soluble items in the research-peptide category, and it typically dissolves quickly and cleanly into a clear, colorless, particle-free solution. Gelling is not expected, and the absence of any gel is the normal result. The volume of water chosen is generally about how conveniently the solution can be measured rather than about any solubility ceiling, so a range such as roughly 2 mL to 3 mL per vial is common. There is no published reconstitution or stability study specific to the acetylated, amidated analog, so these ranges reflect general Epitalon and short-peptide practice rather than validated data for this exact modification.

Add the water slowly down the inside wall of the vial rather than jetting it directly onto the powder cake, then swirl or roll gently instead of shaking hard, which can foam the solution. Give it a minute to fully dissolve. If any material is slow to clear, brief warming to room or body temperature is generally tolerated by short peptides. A finished solution that stays cloudy, shows visible particles, or takes on a yellow or brown tint should be discarded rather than used, since discoloration points to degradation.

Handling and storage

Store the reconstituted solution refrigerated at 2 to 8 degrees Celsius, kept out of direct light. Wipe the rubber stopper with an alcohol swab before each access, and label the vial with the mix date so the age of the solution is always visible. A refrigerated window of roughly four weeks is a common general reference for reconstituted peptides. Discard the vial if the contents turn cloudy or discolored, or if visible floaters or particles appear. Keep any unopened lyophilized powder cold and dry as directed, protected from light, and avoid repeated freeze-thaw cycles.
