Thymulin Zinc
Thymulin, also known as Facteur Thymique Serique (FTS) or serum thymic factor, is a nonapeptide hormone (Glu-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn) produced exclusively by thymic epithelial cells. It is unique among thymic hormones in that it requires zinc to be biologically active - the zinc-thymulin complex (ZnFTS) is the functional form that binds to high-affinity receptors on T-cells.
SubQ injection, any time of day. 10-20 day courses, 2-3 cycles per year with 4-6 months between courses (Khavinson protocol). Pin alone or with other bioregulators only.
Start here. Every protocol below is ordered lowest-first. Begin at the smallest effective dose, hold about a week to assess tolerance, and step up only if needed.
Binds to specific high-affinity receptors on immature T-cell precursors in a zinc-dependent manner, triggering intracellular signaling cascades that promote T-cell differentiation, expression of T-cell surface markers (CD2, CD3, CD4, CD8), and functional maturation.
Modulates cytokine production by mature T-cells, promoting IL-2 secretion and shifting the Th1/Th2 balance. Also enhances NK cell cytotoxicity and modulates B-cell antibody production indirectly through T-helper cell regulation.
Exerts anti-inflammatory effects in the central nervous system by reducing microglial activation and pro-inflammatory cytokine production. Has been shown to reduce neuroinflammation in animal models of pain and neurodegenerative disease.
Days 1-7: No established human timeline. Animal data suggests initial immune cell priming during the first week. Zinc status should be optimized concurrently.
Each reference below was re-fetched from its PubMed record, and the quoted sentence was confirmed to appear in that abstract and to support the claim it sits under. Follow any of them to read the source.
Exact-molecule evidence boundary: the live abstract reports the quoted finding for Thymulin; no broader inference is made.
Thymulin (formerly called FTS) is a well defined nonapeptide hormone produced by thymic epithelial cells.
Thymulin, a zinc-dependent hormone.
Evidence scope. Exact molecule wording appears in the quoted live sentence. Only the population/model, formulation, route, and outcome expressly stated there are supported.
Claims we could not support
No abstract we checked supports these for this molecule at this route. That is not the same as saying they are false — it marks where the evidence is missing.
Dose/route: Per protocol; Subcutaneous (SubQ); Daily. No selected live abstract sentence verified this complete regimen.
Mechanism as written in source JSON. No selected live abstract sentence verified the complete mechanism at the card formulation/route and relevant population/model.
Primary safety claim as written in source JSON. No selected live abstract sentence verified the complete safety claim for this exact formulation and route.
Two different questions: what is documented about running these together, and what is documented about drawing them into the same syringe. A good pharmacological partner can still have to be pinned separately.
Check any specific pair in the Stack & Interaction Checker, which answers both questions separately. Absence of a documented conflict is not evidence of safety.

SubQ
SubQ (estimated; zinc-dependent bioactivity)
T-cell differentiation signals outlast plasma presence; zinc status modulates duration
Rapid enzymatic degradation (endopeptidases); zinc dissociation inactivates peptide
Storage. Store refrigerated at 2-8C. Protect from light. Extremely sensitive to degradation. Reconstituted solutions should be used promptly.
Research compound only. Not approved for clinical use by FDA, EMA, or any major regulatory agency. No IND applications on record.
