Thymulin 1 vial
A nonapeptide thymic hormone that requires bound zinc for its biological activity.

No independent test of Simple Peptide's Thymulin yet
- We hold no independent tests for Thymulin from any maker yet — unknown stays visible.
- We couldn't place this listing's price — its size isn't readable or the market's too thin — so there's no cheap-fake check here.
How to verify this yourself
To verify before you buy: ask Simple Peptide for the Janoshik COA for your batch number, then paste it into Verify — VialGrade confirms it's a real, unedited lab record.

What is Thymulin?
Preclinical / animal onlya.k.a. FTS (Facteur Thymique Sérique)A zinc-dependent thymic hormone studied in immune research.
Good to know: Its zinc dependence means measured or administered activity is highly sensitive to zinc status, and no controlled human supplementation trials establish a clinical benefit.
How does Thymulin work?
A zinc-dependent nonapeptide (FTS bound to zinc) produced by thymic epithelial cells that promotes T-cell differentiation and balances Th1/Th2 immune responses; it loses activity without bound zinc.
Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.
What is Thymulin researched for?
Studied for immunosenescence and age-related decline in T-cell function.
- Immune & thymicStudied in immune-modulation and thymic-function research.
How far has the research gone?
Preclinical / animal research — well-characterized mechanistically, but human data are largely observational (correlating declining thymulin levels with age), not interventional.
Where the science stands — an approved drug is not the same as the research-grade material a vendor sells, which is unregulated regardless.
What should I check before buying?
- Independent purity. Look for a third-party COA (Janoshik or MZ) showing a measured purity — not just a number the vendor typed.
- Batch match. The strongest evidence is a certificate for the exact batch you’ll receive, attributed to this vendor — check the cross-verification on the listing.
- Vendor reputation. See how the vendor is talked about in the community before trusting a new name.
Research context only — VialGrade never gives dosing, medical, or human-use guidance.
The lab evidence
What we could verify
Each row answers a different question. Passing the identity test doesn’t mean it’s sterile or correctly dosed — we show each answer separately.
Identity — independent test
UnknownNo independent third-party COA is advertised or on record for this listing.
Measured purity (HPLC)
UnknownNo independent purity figure is on record for this listing.
Batch traceability
UnknownNo specific batch on this listing has been matched to an independent record.
Sterility & endotoxin
Not testedA purity COA does not measure sterility or endotoxins — no such test is on record.
Dose / fill accuracy
UnknownVialGrade does not independently measure vial fill or delivered dose.
No third-party testing to cross-check
This listing doesn't advertise independent lab testing, and we don't hold an independent record for Simple Peptide's Thymulin. Absence of a certificate isn't proof of anything — but there's nothing here to verify.
- Independent testing. No third-party COA advertised or on record.
Cross-checks the vendor’s testing claim against independent lab records. Purity is read from the lab's certificate as issued — VialGrade doesn't re-run the assay or sample the vial. It reflects one lab's result for one submitted batch, not every vial. Never a statement that a product is safe, sterile, or correctly dosed.
Research-use-only — not FDA-approved
Sold “for research use only,” this compound is not FDA-approved for human use and has not been evaluated for safety, purity, or sterility in people. It is generally not a scheduled controlled substance, so buying it as a research chemical is typically not itself a drug crime — but marketing or using it as a drug is not lawful, and it is not a dietary supplement.
