Overview
Lipo-C is a multi-component preparation pairing the methionine + inositol + choline (MIC) trio with one or more B-vitamins (commonly B-12). The components are characterized cofactors and metabolites of lipid and methylation metabolism — methionine a sulfur-donor amino acid, inositol a phosphatidyl-inositol precursor, choline a phosphatidylcholine precursor, and the B-vitamins supporting the associated cofactor pools — and the preparation is referenced here as a characterized multi-component standard, not for any metabolic-support or weight-management outcome. Because Lipo-C is a defined-composition mixture rather than a single chemical entity, identity is established at the component level: each component is confirmed by the appropriate method (HPLC and mass-spec identity for the small-molecule components; the exact B-vitamin form confirmed and stated), and the documented formulation is reported against the specification. The components carry individual CAS numbers rather than a single registered identifier; confirm each component's API and the B-vitamin form by COA / label before use. It is supplied as a pre-prepared aqueous solution in 10 mL vials. This is reference-grade research material, distinct from compounding-scale API supply.
Applications & buyer fit
Other research peptides in this category — Melanotan I, Melanotan II, PT-141, ACE-031, Adipotide / FTPP, EPO, HMG — ship to research labs studying topics outside the GH / cognitive / immune / mitochondrial / repair / longevity / Khavinson clusters. Each peptide has its own analytical-packet emphasis (e.g. glycoprotein bioassay in IU for HMG; cyclised-form confirmation for oxytocin) noted in the per-product CoA scope.
Academic Laboratories
Universities, medical schools, and government research institutes qualifying a reference standard for a method-development or in vivo workflow.
Contract Research Organisations (CROs)
CROs running preclinical and translational studies on behalf of academic, biotech, or pharma sponsors who need traceable reference material across multi-site campaigns.
Every lot has its own batch-specific CoA — RP-HPLC purity, ESI-MS identity, bacterial endotoxin and fill amount, plus any analytical scope agreed at quote stage — tied to the exact lot you receive.
Review a representative batch CoA before you order, so you can confirm the packet matches what your method or sponsor audit needs.
Supplied strictly as a research reagent to research institutions — not a finished dosage form and not for human administration. Buyer qualification runs at the inquiry stage.
Regulatory note
Defined-composition multi-component preparation; components carry individual CAS numbers. Confirm each component's identity and the exact B-vitamin form by batch COA / label before use. Lyochem supplies Lipo-C strictly for Research Use Only; buyers are responsible for verifying ingredient eligibility in their destination market.

Frequently asked questions
Because Lipo-C is a compounded blend (methionine, inositol, choline, and B-vitamins) rather than one molecule, Lyochem releases it against per-component analytics: each component is confirmed by its own LC-MS or assay identity check, the B-vitamin form is stated, and the documented formulation ratio is reported on the COA. A single purity number is not meaningful for a multi-active preparation, so the batch record is component by component.
B12 exists in several forms (cyanocobalamin, methylcobalamin, hydroxocobalamin) that differ in mass and stability, so Lyochem confirms the specific form present by LC-MS against its expected mass and states it explicitly on the COA rather than leaving it implied. Research that depends on a particular cobalamin form should verify it on the lot documentation before use.
Send any vial from your order to an independent laboratory of your choice. If the report shows the product does not meet the specification on its COA — purity below the stated minimum, or an identity that does not match — share the report with our sales team and we refund that product in full.
