Plain-spoken notes on the compounds we supply — what the literature shows, how to read a COA, and the protocols that protect your data. Cited, never hyped.
Bioregulators
Cardiogen is the AEDR tetrapeptide from the Khavinson family. Real chemistry, but its cardiac evidence is thin, single-lab, and unreplicated. An honest look.
Cerluten is a natural cerebral-cortex peptide extract in the Cytomax line. A PubMed search returns zero studies under its name. Here is the honest…
Bioregulators
Livagen is the tetrapeptide Lys-Glu-Asp-Ala (KEDA), a Khavinson liver bioregulator studied for chromatin decondensation in old-donor lymphocytes. A cited, RUO look at the real…
Methods & QC
Why short Khavinson bioregulators (KE, EDR, AEDG/epitalon, KED) resist oxidation and deamidation as dry powders — a sequence-based QC argument, honestly stated.
Bioregulators
A literature map of the Khavinson ultra-short peptides — Epitalon, Pinealon, Vesugen, Vilon, Thymogen, Pancragen, Livagen — by the tissue each has been studied…
Comparisons
Cortagen, Cerluten and Cortexin are three different kinds of material: a synthetic tetrapeptide, an undefined cortex extract, and a registered drug. What the literature…
Bioregulators
Vilon is the synthetic Lys-Glu (KE) dipeptide, the smallest of the Khavinson bioregulators. Its chemistry, mouse and cell-culture literature, and honest limits.
Bioregulators
Thymogen is the synthetic dipeptide L-Glu-L-Trp (oglufanide, CAS 38101-59-6). A structural, mechanistic and honest-evidence look at this Khavinson-school immunoregulator.
Thymalin is a calf-thymus polypeptide bioregulator developed by Khavinson and Morozov. Its chemistry, mechanism, evidence base, and the CAS mix-up, explained.
Methods & QC
Lyophilized peptide powder is kinetically arrested and tolerates brief ambient excursions; the reconstituted solution needs 2-8 C. The degradation chemistry, referenced.
Regulation
Tesofensine has no EMA marketing authorisation and is not an EU-scheduled controlled substance — but it remains an unapproved investigational compound. The 2026 regulatory…
Occasional, considered notes on the compounds and the literature. No noise.
