Lipo-C (Carnitine + B-Complex Lipotropic) Certificate of Analysis
Source batch LZ-LIPC-260826 · certificate LZ-COA-LIPC-260830 · analysed August 27, 2026
This Certificate of Analysis covers batch LZ-LIPC-260826 of Lipo-C (Carnitine + B-Complex Lipotropic), manufactured on August 26, 2026 and analysed on August 27, 2026. This is a co-formulation of 5 components: L-Carnitine, Cyanocobalamin, L-Methionine, Inositol, Choline Cl. Each is assayed against its own reference standard, and the headline figure of 99.24% is the LOWEST single-component purity, not a figure for the mixture. The batch was released on August 29, 2026 and independently confirmed by Janoshik Analytical, working to ISO/IEC 17025:2017. Every figure below is specific to this batch.
Batch and certificate applicability
This Certificate of Analysis applies specifically to source batch LZ-LIPC-260826 of Lipo-C (Carnitine + B-Complex Lipotropic). All Lipo-C (Carnitine + B-Complex Lipotropic) vial strengths offered under this batch (10 ml) were filled from the same source batch identified above. The certificate therefore reports the analytical results for that source batch and is not a generic or product-wide certificate. Each finished vial carries a lot identifier traceable to source batch LZ-LIPC-260826 through our filling and packaging records. If a subsequent source batch is introduced it receives a separate batch identifier and separate analytical documentation.
