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
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.

Multi-peptide products (e.g. BPC-157 + TB-500). We don't rank these by $/mgPrice divided by the milligrams of active compound — the like-for-like way to compare cost across different vial sizes. — a per-milligram figure across different peptides isn't comparable — so they're listed separately by total price and kept out of the headline index above.
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.

Stimulating a successful host immune response may be a promising helpful therapy to achieve elimination of hepatitis B virus (HBV) infection in chronic hepatitis B (CHB). Thymosin α-1 (Tα-1), as an immunomodulatory agent, can enhance…
Aging is characterized by immune decline, mainly due to thymic involution-the age-related shrinkage of the thymus gland. This leads to reduced T-cell production, chronic inflammation, and increased susceptibility to age-related diseases.…

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.
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.
