Lipo-B
Also called Lipotropic injection with B12; MIC + B12
A compounded injectable blend of methionine, inositol and choline (MIC) with vitamin B12, often added to weight-loss programs. It is not a peptide, and the blend has not been tested in randomized trials.
Overview
What it is
A mix of nutrients made by compounding pharmacies, not a single molecule. Formulas vary; most contain methionine, inositol and choline, plus cyanocobalamin or methylcobalamin, and some add L-carnitine (see Lipo-C) or other B vitamins.
How it works
The ingredients are called lipotropics. Choline and methionine help the liver package and export fat, inositol is involved in cell signaling and fat metabolism, and B12 supports energy metabolism. Whether injecting them adds anything for people who already get enough from diet is unproven.
What the research shows
No randomized trial of the injectable Lipo-B combination for weight loss was found. Evidence is limited to the biology of each ingredient and to B12's benefit in people who are deficient. Clinic dosing schedules reflect local practice rather than tested protocols.

Safety and regulatory status
Safety and side effects
Injection-site pain and redness are most common; stomach upset can occur. Tell your provider about liver or kidney disease. Rare allergic reactions, including to cobalt in B12.
Regulatory status
Not FDA approved. It is a compounded product with no single approved formula, and FDA has not evaluated its safety or effectiveness.
Common questions
What is the difference between Lipo-B and Lipo-C?
Both are lipotropic blends. Lipo-B is built around B12; Lipo-C adds L-carnitine. Exact formulas depend on the pharmacy.
Does Lipo-B cause weight loss?
There is no trial evidence that it does on its own. It is usually used alongside diet changes or GLP-1 medicines.
