Independently verified UK research peptides: what 'lab tested' actually means
What independent third-party verification actually requires, why a named laboratory matters more than 'lab tested' language, and how to verify a supplier's claims before purchase.
'Lab tested' is an unregulated phrase. Independent verification means an analytical laboratory with no commercial interest in the result tested a sample from the specific batch you are buying.
The supplier should name the laboratory. A named laboratory can be contacted and its reports cross-referenced; an anonymous one cannot.
Every flagship compound in this catalogue is released against a batch-specific report, and the lot number is searchable on the verification page before you order.
