No independent test of Umbrella Labs' Thymosin Alpha-1 yet
- Thymosin Alpha-1 generally tests around 99.6% purity across 5 independent certificates — but from other makers, so treat it as a benchmark, not proof of this seller's stock.
- Price sits within the normal range for Thymosin Alpha-1 — no cheap-fake red flag.
How to verify this yourself
To verify before you buy: ask Umbrella Labs for the Janoshik COA for your batch number, then paste it into Verify — VialGrade confirms it's a real, unedited lab record.

Cheapest Thymosin Alpha-1, by price per mg
Vials come in different sizes, so the sticker price lies. This ranks every listing by what a milligram actually costs — with independent test purity where we have it.

Real $/active mg divides the price-per-mg by the measured purity — the honest cost of the actual peptide, so a 90%-pure vial isn’t compared as if it were 99%. Too cheap? flags a listing far below the market rate — often underdosing or a fake, not a deal. The crown marks the cheapest non-outlier; best value marks the lowest real cost per active mg.
Understand this compound
What is Thymosin Alpha-1?
Widely studieda.k.a. Zadaxin, Tα1A thymic peptide (Zadaxin) studied in immune-modulation and antiviral research.
Good to know: Despite a large international trial base, it lacks current FDA approval in the US, and the FDA has flagged immunogenicity and quality concerns for compounded versions.
How does Thymosin Alpha-1 work?
A 28-amino-acid thymic peptide that activates Toll-like receptor 9 (TLR9) signaling on dendritic cells, promoting T-helper-1 polarization and coordinated adaptive immune responses.
Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.
What is Thymosin Alpha-1 researched for?
Studied for chronic viral hepatitis (B and C), as an immune adjuvant in cancer, and for sepsis/immune modulation.
- Immune & thymicStudied in immune-modulation and thymic-function research.
How far has the research gone?
Widely studied — evaluated in 30+ trials (roughly 11,000 patients) internationally and approved in 35+ countries (e.g., China, Italy) as Zadaxin for hepatitis B, but not currently FDA-approved in the US.
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.
These certificates are for Thymosin Alpha-1 across every maker VialGrade tracks — not necessarily Umbrella Labs’s own stock. This listing’s specific evidence is the matrix above.
Independent testing
Independent lab tests on record for Thymosin Alpha-1
Real, publicly verifiable third-party tests. Purity is read from the certificate itself. A test reflects one lab’s result for one submitted batch — not a guarantee that every vial matches.
How does this data get here?
Every record below is a real certificate of analysis, gathered two ways: from the public verification feeds that independent labs (like Janoshik) publish, and from the certificates vendors post on their own product pages. We open each certificate document and read the measured purity, content, batch, and date directly off it — a scraper can’t read a number printed inside an image, so this is done by machine vision, then recorded here with a link back to the original.
Nothing here is typed in by a vendor or invented by us. Where a certificate is missing, we say so rather than filling the gap.
We re-check the lab feed, too. A “still listed” tag means the certificate is currently public in Janoshik’s database — we re-verify against the live feed and stamp the date. If a cert is later pulled, the tag flips. It’s a freshness check on the same source, not a second independent opinion.
What a certificate does & doesn’t prove
Three different questions. Purity (“how clean?”), identity (“is it the right molecule?”, a mass-spec test), and content (“did I get the labeled mg?”) are separate. A vial can be 99% pure and still be the wrong peptide, or the right peptide underdosed. We flag the measured dose against the label above; underdosing is the most common real fraud.
Who submitted the sample matters. Most of these are vendor-submitted — the seller chose which vial to send, so one good certificate doesn’t prove every batch is the same. The gold standard is a blind test, where a buyer sends a vial they bought as a normal customer. Same label doesn’t prove same product; same batch number doesn’t prove same batch.

No test for this vendor — but Thymosin Alpha-1 is independently characterized
This vendor doesn't advertise independent testing, and we hold no COA tied to Umbrella Labs specifically. We do hold 5 independent certificates for Thymosin Alpha-1 (median 99.6% purity) from other makers — real market context for what this compound tests at, though not proof of this vendor's product.
- This vendor. No third-party COA on record for Umbrella Labs.
- Thymosin Alpha-1 (market-wide). 5 independent COAs, median 99.6%.
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.
