Fourteen vendor-named BioViridian reports match the laboratory’s published originals. Six additional four-page reports from Krause Analytical, commissioned through Finnrick, are available with neutral View COA labels because independent issuer confirmation is unavailable. All 20 report sets cover identity, purity and content. The Krause methods appendix describes endotoxin and metals methods but gives no sample results for them. No retained report supplies sterility or residual-solvent results.

Report limitations
The GLOW and KLOW reports give a full-length TB4 molecular weight while the supplier describes an acetylated seven-residue TB-500 fragment. Those offers and their certificate attachments are held for identity review. One archived 30 mg report prints a lot number the vendor assigns to its 15 mg fill. Two Krause semaglutide samples were submitted with a GHK lot label; their 30 mg semaglutide attribution is the vendor’s correction and remains separate from the laboratory result. Other disclosed CAS-number differences are retained with the affected reports.
