About This Comparison
This page tracks listed prices for Thymosin Alpha-1 across 15 research-compound vendors, spanning 2 vial sizes. Prices are shown in USD and normalized to a per-mg cost so sizes can be compared directly. In-stock status is tracked per size, and the lowest in-stock price per mg is flagged as best value. For mechanism, dosing ranges, half-life and citation data, see the Thymosin Alpha-1 research profile.
Methodology
- Prices are aggregated from listed research-compound vendor catalogs and refreshed on a regular cadence.
- Per-mg cost is computed from each vendor's listed vial size, so a lower total price is not always the lower per-mg price.
- Certificate of Analysis (COA) availability is flagged per vendor where a third-party lab report is provided.
- Listings are compiled for research purposes only. Amino Axiom does not sell compounds and does not verify vendor claims beyond published COA data.
