How are Thymulin prices verified on Disclosed Labs?
Every listed vendor holds a Grade C or better trust score, computed independently from lab Certificates of Analysis — not from payments or sponsorships. Prices are scraped and fact-checked daily. Vendors cannot pay to improve their ranking.
Check formulation: Lyophilized powder requires reconstitution before use. Pre-mixed solutions are more convenient but may have a shorter shelf life and higher prices.
Compare per-mg cost: Different strengths and quantities make direct price comparison difficult. Calculate the per-milligram cost to find the true best value.
Verify COAs: Look for vendors that publish per-batch Certificates of Analysis from named, accredited labs. Use the Full safety panel filter to require endotoxin, sterility, and heavy-metals testing on the current batch — not just HPLC purity.
Bach and Dardenne originally characterized FTS/thymulin and its absolute zinc dependency (Bach & Dardenne, Med Oncol Tumor Pharmacother 1989, PMID 2657247). Prasad et al. (J Clin Invest 1988, PMID 3262625) showed that serum thymulin activity falls in human zinc deficiency and recovers with zinc supplementation. Mocchegiani et al. (Int J Immunopharmacol 1995, PMID 8582782) demonstrated partial reversal of thymic involution with zinc in aged mice. Dardenne & Pleau reviewed zinc-thymulin interactions (Met Based Drugs 1994, PMID 18476235). Safieh-Garabedian et al. (Br J Pharmacol 2002, PMID 12110619) reported analgesic/anti-inflammatory activity of a thymulin-related peptide in rats. There are NO large, modern RCTs of exogenous thymulin in humans; clinical use is experimental.
