Legally established 2026 · Spain, European Union
Independent testing you can verify, not just trust
Convalence Labs is a newly established independent laboratory, opened in 2026. Built by senior analysts with over 15 years of combined experience in qualitative and quantitative molecular identification. We exist to audit the real composition, purity, and exact dosage of peptides, proteins, and advanced active ingredients, with every sample tested against certified reference standards, and every certificate independently verifiable online.
Who we are
We collaborate with researchers, athletes, and industry professionals to provide detailed insight into what a sample actually contains, not what its label claims. Being new gives us no legacy client relationships or supplier ties to protect: our only business is testing, so every result stands on its own.
Mission & values
Confidentiality
Confidential, anonymised test reports: your identity and submission details stay private.
Precision & accuracy
Orthogonal GC-MS, NMR, and HPLC methods, cross-checked against certified reference standards.
Integrity & independence
We test only, with no formulation, manufacturing, or sales, so results carry no conflict of interest.
EU-wide coverage
Serving clients across the European Union, with digital certificates verifiable from anywhere.
Coverage and scope
A logistics network built for the secure transport of chemical compounds lets us process analytical requests from clients located within the European Union. We specialize in the thorough characterization of complex chemical matrices, including pharmaceuticals, peptides, and sports-related additives, while supporting both private individuals and product-development companies. In line with legal counsel, we do not accept opioids or other internationally controlled narcotics for analysis. Every analysis ends with a hash-verified digital report, instantly verifiable by any third party through our public platform.
