Methionine / Inositol / Choline + B-vitamin lipotropic blend
Overview
Lipo-C (also marketed as MIC injections, lipotropic injections, or 'fat-burner' shots in the med-spa industry) is a multi-component lipotropic blend combining the methionine + inositol + choline (MIC) trio with one or more B-vitamins (typically B-12, sometimes B-6, B-complex, or pyridoxine). The components are not pharmacological fat-burners in the chemical sense; rather, methionine is a sulfur-donor amino acid involved in lipid metabolism, inositol is a phosphatidyl-inositol precursor relevant to lipid signaling, choline is a phosphatidylcholine precursor involved in fat transport from the liver, and the B-vitamins support the methylation and energy-metabolism cofactor pools the other components depend on. The combination is marketed in med-spa contexts as a metabolic support and adjunct to weight-management programs. PeptideXpo supplies Lipo-C in both lyophilized (10 mg) and pre-mixed aqueous solution (10 ml) formats at ≥99.0% HPLC purity for each component. The exact formulation varies by buyer specification, both the MIC-trio ratios and the B-vitamin form (cyanocobalamin vs methylcobalamin vs hydroxocobalamin) can be customized per OEM specification. The release packet certifies each component identity and the documented formulation against the buyer specification.
Who buys this, and why
Custom-blend buyers are almost always OEM clients building a branded product around a specific ratio of two or more peptides. The development workflow is collaborative: ratio target, analytical method to verify it, stability protocol in the chosen carrier, and packaging selection are all defined in the OEM brief before the first commercial run. Sample-stage volumes are usually 5-10 g of finished blend; commercial MOQ depends on the components.
Primary buyer fit: medical aesthetic clinics and med spas and regional distributors and re-sellers.

Regulatory note
Sold as a multi-peptide active for research and for OEM-formulated finished products under the receiving brand's regulatory framework. Blend composition, finished-product safety, labeling claims, and notification responsibilities remain with the brand owner. Component-level analytical data is supplied for every batch.
Frequently asked questions
The MIC trio plus B-vitamins each support different aspects of fat metabolism without being pharmacological 'fat burners': **Methionine** is a sulfur-donor amino acid involved in lipid metabolism and the methylation cycle. **Inositol** is a precursor to phosphatidyl-inositol, relevant to lipid-signaling pathways. **Choline** is the precursor to phosphatidylcholine and a key component of lipoprotein-mediated fat transport from the liver, choline deficiency causes hepatic fat accumulation. **B-vitamins** (especially B-12 and B-6) are essential cofactors for the methionine and choline metabolism pathways. The combination supports normal fat-metabolism pathways at supraphysiological doses; it is not a direct lipolysis-stimulating agent like a beta-3 adrenergic agonist would be.
Yes, both the MIC-trio ratios and the B-vitamin form can be customized per OEM specification. Common variations include: using methylcobalamin instead of cyanocobalamin for the B-12 component (preferred in some methylation-cycle-impaired patient populations), adjusting the inositol:choline ratio (some protocols favor choline-heavier formulations), and adding L-Carnitine or other complementary actives to the base. The OEM workflow defines the target formulation, the analytical method to confirm each component, and the documentation scope before commercial production. PeptideXpo can supply either the standardized Lipo-C blend or fully custom formulations through the OEM service.
