2 independent third-party assays of Thymosin Alpha 1, covering 2 vendors.
Measured purity across those assays runs from 99.7% to 99.9%, median 99.9%. The spread is the point: it is variation between lots and between vendors, not a single number that describes the compound.
Assay dates span 2024-04-15 to 2026-02-12.
Manufacturer recorded on the certificates: Elevated Healing, Pacific Wave.
Thymosin Alpha-1 carries an evidence grade of C on this site (Phase I–II Clinical Trials). Thymosin alpha-1 (Ta1) is a clinically proven, 28-amino-acid peptide (MW ~3,108 g/mol, Ac-Ser-Asp-Ala-Ala-Val-Asp-Thr-Ser-Ser-Glu-Ile-Thr-Thr-Lys-Asp-Leu-Lys-Glu-Lys-Lys-Glu-Val-Val-Glu-Glu-Ala-Glu-Asn-OH) naturally produced by the thymus…
A certificate of analysis describes the lot that was submitted and nothing else. It is not a guarantee about a later batch, and purity is not identity — a sample can assay clean and still be the wrong compound, or the right compound at the wrong concentration. Vendors with no assay row below have not been tested here, which is not the same as having failed.
