Epithalon

Note on where the literature comes from

Almost the entire published record on this peptide traces to one research group, led by Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology, and a large share of it appeared in a single journal across two decades. Concentration in one laboratory is not evidence of error, but it does mean the ordinary check of independent replication was largely absent from the field.

That changed in 2025, when a group at Brunel University London published an independent examination across several human cell lines. Both the 2003 original and the 2025 independent work are listed below so the two can be compared directly rather than either taken on trust.

Results, this lot

Purity and content figures above are specific to lot EPIT50-02112026-J and are not a specification carried across other lots. Content measurement carries unusual weight at a 50 mg fill, where a shortfall that would be marginal in a 5 mg unit becomes a material difference in the quantity received. Each lot is tested individually and reports its own results.

03

Panels differ between products and between lots. What follows is the scope of testing performed on this lot. Nothing is claimed unless it appears on the certificate for the lot supplied.

Identity confirmation is less discriminating on a four-residue molecule than on a longer chain, since a tetrapeptide is too small to carry a multi-state charge series and elutes early on a reversed-phase column. Where certainty at this size is material, amino acid analysis or a second orthogonal method is the appropriate check. Where a parameter is material to intended laboratory work, purchasers should verify it independently or source material released against that specification.

04

Preparation conditions are the responsibility of the receiving laboratory. Verum provides no protocol, no preparation instruction, and no guidance on use.

05

References are listed for bibliographic purposes and are indexed by the experimental system used. Each description states what the study measured, not what it concluded, and the originating group is named so the concentration of the literature is visible rather than obscured. Every entry was conducted in cell culture. Studies conducted in human participants are excluded. Verum has no involvement in any of this work and makes no representation as to its applicability.

Findings in cultured cells do not establish an effect in any whole organism. Nothing in the above is offered as a representation about this material.
