Thyreogen
Also known as: Thyroid peptide bioregulator · Thyroid tetrapeptide · BioThyroid
A thyroid-targeting tetrapeptide bioregulator from the Khavinson series. Normalizes thyroid cell function, thyroid hormone synthesis, and thyroid morphology. Studied for hypothyroidism, autoimmune thyroiditis, and thyroid aging. One of the most widely used Khavinson organ bioregulators given the high prevalence of thyroid dysfunction.
What is Thyreogen? A thyroid-targeting tetrapeptide bioregulator from the Khavinson series. Normalizes thyroid cell function, thyroid hormone synthesis, and thyroid morphology. Studied for hypothyroidism, autoimmune thyroiditis, and thyroid aging. One of the most widely used Khavinson organ bioregulators given the high prevalence of thyroid dysfunction.
How does Thyreogen work? Thyreogen penetrates thyrocyte nuclei and regulates transcription of genes involved in thyroid hormone synthesis (thyroglobulin, TPO, NIS). It normalizes TSH receptor sensitivity, reduces thyroid autoantibodies, and restores thyroid morphology in autoimmune thyroiditis models. Unlike hormone replacement, it targets the root cause of reduced thyroid function.
Benefits of Thyreogen: Normalizes thyroid cell function and hormone synthesis; Reduces thyroid autoantibodies in Hashimoto's models; Restores thyroid morphology in aging; Improves TSH sensitivity without hormone replacement; Anti-aging effects in thyroid tissue; Studied for subclinical hypothyroidism; Supportive therapy during thyroid recovery
Thyreogen dosage: Standard Khavinson protocol: 1-2mg/day for 10 days, 2x per year. Monitor TSH, T3, T4 before and after cycle.

Mechanism of Action
Thyreogen penetrates thyrocyte nuclei and regulates transcription of genes involved in thyroid hormone synthesis (thyroglobulin, TPO, NIS). It normalizes TSH receptor sensitivity, reduces thyroid autoantibodies, and restores thyroid morphology in autoimmune thyroiditis models. Unlike hormone replacement, it targets the root cause of reduced thyroid function.

KEDA tetrapeptide
A synthetic tetrapeptide (Lys-Glu-Asp-Ala) from the Khavinson bioregulator series that de-heterochromatinizes age-condensed chromatin in lymphocytes, restoring youthful gene expression patterns. Hepatoprotective and immunomodulatory. One of the most mechanistically unique anti-aging peptides — it directly reactivates genes silenced by chromatin condensation with age.
Ventfort
Vascular wall peptide bioregulator
A peptide bioregulator targeting blood vessel walls from the Khavinson series. Normalizes vascular endothelial cell function, reduces oxidative damage to vessel walls, and improves microcirculation. Distinct from Vesugen (which is the synthetic tripeptide form) in being the natural extract-based vascular bioregulator complex.
Vilon
Lys-Glu
A synthetic dipeptide from the Khavinson bioregulator series. Primarily acts as a thymus and immune regulator with demonstrated anti-aging properties.
Endoluten
BioPineal
A natural pineal gland peptide bioregulator complex. Distinct from Epithalon (synthetic tetrapeptide) and Pinealon (synthetic tripeptide), Endoluten contains natural pineal peptide fractions that regulate melatonin production, circadian rhythms, and age-related neuroendocrine decline.
