    Vendor profile

Tiers name what a vendor publishes, not a verdict on any product's purity or quality. Lab-verifiable COAs: certificates that open on the testing lab's own site (the seal's ring shows what share of them do). Third-party COAs: certificates attributed to a third-party lab, which may be hosted only on the vendor's site. Tiers follow the Vendor Score (90+ and 80–89), which is 87% COA evidence; the numeral in each seal is that score. Affiliate relationships never affect tiers, selection or order. How the Vendor Score works

Cheapest per vial size

$/mg usually drops as vials get bigger, so the cheapest $/mg overall is often a big vial. Compare inside the size you would actually order. The size with the most listings is 10 mg.

Thymosin Alpha-1 (Tα1) is a 28-amino-acid synthetic peptide originally characterized from the thymic protein prothymosin alpha. It appears in laboratory research as a reference peptide studied in immunology-related contexts. It is chemically and structurally distinct from TB-500 (a thymosin beta-4 fragment) despite the shared "thymosin" naming. This index tracks research-use-only (RUO) vendor pricing for Thymosin Alpha-1 to help researchers compare cost across suppliers.

Evidence brief

Thymosin alpha-1 is a synthetic immune-modulating peptide (studied and marketed in some countries as the drug thymalfasin) evaluated in randomized trials and meta-analyses, almost entirely in specific patient populations rather than healthy people.

▸ Why compare $/mg for Thymosin Alpha-1?

Per-milligram prices for Thymosin Alpha-1 vary across vendors because of differences in synthesis scale, stated HPLC purity, fill quantity per vial, and how each supplier documents identity and lot testing. Comparing normalized $/mg lets a researcher weigh a lower headline price against purity grade and vial size so the true cost of usable material is clear.

▸ Reading the COA

For Thymosin Alpha-1, confirm identity by mass spectrometry against the expected monoisotopic/average mass for the 28-residue sequence (roughly 3108 Da for the acetylated form), since it is easily confused on a label with TB-500/thymosin beta-4 fragments. Look for HPLC purity stated at 98%+ with the chromatogram attached, and treat missing or generic COAs as unverified. Common quality flags include deletion/truncation sequences and residual TFA counter-ion, so check that the report references this specific peptide's lot number rather than a boilerplate template.

▸ FAQ

How is lyophilized Thymosin Alpha-1 typically stored as a research material?
As a general storage note for research material, lyophilized peptides like Thymosin Alpha-1 are commonly kept sealed, desiccated, and frozen (often -20°C or colder) for long-term storage, protected from light, moisture, and repeated temperature cycling. Dry powder is generally more stable than reconstituted material. This is storage information only and not use guidance.
What is a COA and what should I check on one for Thymosin Alpha-1?
A Certificate of Analysis (COA) is a lot-specific document reporting a material's identity and purity. For Thymosin Alpha-1, check that mass spectrometry confirms the expected mass for the 28-residue sequence (not a TB-500 fragment), that HPLC purity is stated with an attached chromatogram, and that the lot number on the COA matches the vial you received.
Why does the per-mg price of Thymosin Alpha-1 differ so much between vendors?
Differences come from synthesis batch size, stated purity grade, the amount of peptide per vial, and the depth of analytical documentation. A vial priced low overall may carry a higher $/mg once fill quantity is normalized, while higher-purity, fully-documented lots often cost more per mg, which is why normalized comparison is useful.

All products listed are sold by third-party vendors for laboratory and research use only (RUO). Where an FDA label, a peer-reviewed study or a clinical-trial registry entry has published a dose, pepmg reports it with the source named and the tier labeled (a registry figure is marked trial registry, not peer-reviewed), because that is safer than guessing. It is a report, not medical advice and not a recommendation to use anything. pepmg sells nothing and ships nothing. Listings are price-tracking data, not endorsements.
