Every Thymosin Alpha-1 listing, cheapest per mg first

Sticker prices hide the size, so listings are ranked by what a milligram actually costs — with independently tested purity where it exists. All 29 are here: the last 6 are listings whose vendor never published a strength we can read, so they have no per-mg figure to sort on.

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. A vendor shown as Unavailable or Low stock is priced here but not currently buyable.

Understand this compound

What is Thymosin Alpha-1?

Widely studieda.k.a. Zadaxin, Tα1

A thymus-gland molecule that helps coordinate the immune system's response. Approved in 35+ countries as Zadaxin for hepatitis B — but not in the US.

Immune & thymic

⚠

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?

The science

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 is a separate question with its own answer — one green row never vouches for the rest.

Identity

Established

An independent lab record backs this vendor's testing for this compound.

Measured purity

Established

Independently measured 99.35%. Read from the certificate, not re-measured by VialGrade. Purity is not a grade.

Batch traceability

Unknown

No batch on this listing matches an independent record.

Sterility

Not tested

A purity certificate doesn't measure this — no such test on record.

Dose accuracy

Unknown

Not something VialGrade measures — no test on record.

These certificates are for Thymosin Alpha-1 across every maker VialGrade tracks — not necessarily Chameleon Peptides’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.

US legal status

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.
