Beyond the literature: here's what third-party Certificate-of-Analysis records (Janoshik, BCC, Auxlabs) say about real TB-500 and Thymosin Alpha-1 batches we've tested. Aggregate, public data — cross-reference against the studies below.
We tested 2228 TB-500 batches across 786 manufacturers, 99.0% avg purity.
We tested 5 Thymosin Alpha-1 batches across 2 manufacturers, 99.8% avg purity.
We hold deeper lab coverage on TB-500 (2228 batches tested). Thymosin Alpha-1 edges ahead on average measured purity (99.0% vs 99.8%) — a narrow gap; weigh it against failed-batch and underdose counts above.
Studies in our corpus that mention both TB-500 and Thymosin Alpha-1 — the gold-standard direct comparison evidence.
This robust and expanding patenting activity unequivocally underscores the escalating commercial and clinical interest in thymosin peptides as a promising class of therapeutics. The identification of rapidly emerging therapeutic areas, particularly in oncol…
