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.

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.

Benefits

  • 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

Side Effects & Risks

  • Monitor thyroid function labs during use
  • Possible temporary hyperthyroid symptoms if overcorrecting function
  • Injection site reactions

Storage & Reconstitution Guide

Storage Temperature

-20°C (lyophilized)

24 months (lyophilized), 28 days (reconstituted)

Reconstitution Solvent

Bacteriostatic water (BAC water)

Swirl gently — do not shake or vortex

Handling Notes

Protect lyophilized peptide from moisture and light. Once reconstituted, keep refrigerated. Discard if solution becomes cloudy or discolored. Use insulin syringe for precise dosing.

Step-by-Step Reconstitution

1

Gather supplies

BAC water, insulin syringe, alcohol swabs, vial

2

Disinfect tops

Swab rubber stoppers of both vials with alcohol

3

Draw BAC water

Pull desired mL of BAC water into syringe

4

Inject slowly

Inject BAC water down the side of the peptide vial, swirl gently to dissolve

Livagen

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.

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.
