MIC / B12 injections: evidence, legality and safety

Quick answer

FDA status, read October 15, 2026MIC-B12 (methionine, inositol, choline + B12): Mixed: some parts Category 1, some Category 3, some not listed. Choline chloride and methylcobalamin are Category 1; choline bitartrate and inositol hexanicotinate are Category 3; methionine, inositol and cyanocobalamin do not appear on the category lists (they may qualify by another route, such as a USP monograph, which we did not check). No MIC-B12 product is FDA-approved for weight loss.

MIC injections combine methionine, inositol and choline, often with vitamin B12, and are marketed by wellness clinics as 'lipotropic' or fat-burning shots. There is no robust evidence that MIC/B12 injections cause weight loss, and they are compounded products, not FDA-approved weight-loss drugs.

Regulatory statusCompounded 'lipotropic' injections; weight-loss efficacy is not established.

What does the evidence actually show?

What human clinical evidence exists?

No robust controlled evidence supports the fat-loss marketing.

What do the animal and laboratory studies show?

The components have defined metabolic roles; this does not establish a weight-loss effect from injection. We keep animal and laboratory findings clearly separated from human evidence, because preclinical results routinely fail to translate to people.

What are the known and potential risks?

Injection-site reactions and the general concerns of compounded injectables.

No consumer dosing for research compoundsThis page does not provide dosing instructions for unapproved compounds, and we do not link to research-chemical sellers. If you are considering peptide therapy, do it through a licensed clinician who can weigh your individual risks.

Is it legal, and where does it come from?

The lawful pathway for any prescription peptide is a licensed clinician and a licensed pharmacy. Products labeled "for research use only" are not lawfully sold for human consumption. See how to verify a peptide provider and research peptides versus prescription therapy.

Is it banned in sport?

Verify B12 dosing route rules; generally not prohibited.

Frequently asked questions

Is MIC / B12 injections FDA-approved?

Compounded 'lipotropic' injections; weight-loss efficacy is not established.

Is there human evidence for MIC / B12 injections?

No robust controlled evidence supports the fat-loss marketing.

Is MIC / B12 injections legal to buy?

Many peptides in this category are sold as 'research chemicals,' which is not a lawful pathway for human use. Legitimacy depends on approval status and whether a licensed clinician and pharmacy are involved. We do not link to research-chemical sellers.

Is MIC / B12 injections banned in sport?

Verify B12 dosing route rules; generally not prohibited.

How the dates on this page work. Manufacturer self-pay prices were re-read on 15 October 2026: NovoCare’s Wegovy page and Lilly’s Zepbound savings page. Foundayo prices are carried from LillyDirect pages archived 25 September 2026, because lilly.com blocked automated reads. Figures captured from telehealth provider websites carry the date we read that provider’s page, which may be earlier; where it is, the row or a dated notice says so. We do not restamp a figure we have not re-read.
