Lipo-C
Lipo-C (lipotropic injection: methionine, inositol, choline plus L-carnitine)
What is Lipo-C?
Lipo-C: Compounded 'lipotropic' injection of methionine, inositol and choline (MIC), often plus B12 and sometimes L-carnitine/B-vitamins ('Lipo-C' typically adds carnitine). The sources cited here most often discuss it for: Fat burning, unproven; Liver fat handling, nutrient data only; Energy from B12, unproven. Evidence label: Unstudied.

While many clinics boast about their possible benefits for weight loss, note that very little research has examined the effects of lipotropic injections on weight loss.

What is Lipo-C researched for?
The three outcomes most discussed for Lipo-C in the sources below, as those sources report them. humanpeptides.fyi makes no claims of its own: a listed benefit can be unproven or can have failed in trials, and the label on each line says which.
Liver fat handling, nutrient data only
- Liver fat handling (choline component): choline is an essential nutrient; human choline deficiency causes reversible fatty liver, corrected by repletionhuman controlled data for the nutrient, not the injection1
Energy from B12, unproven
- Energy (B12 component): B12 corrects fatigue/anemia only in documented deficiency; little evidence of energy boost in non-deficient peoplemeta-analysis cited in pharmacy review1
What do researchers and users say about Lipo-C?
I take Lipo-C with my tirz and it’s been a game changer for me.
Energy report from a user also taking tirzepatide who was unsure how much came from tirzepatide versus the pharmacy-branded lipotropic blend; others in the thread noticed nothing.
What side effects of Lipo-C are reported?
- Injection-site pain/bruising, flushing, metallic/sulfur taste, nausea, headache; rare abscess/anaphylaxis (B12 or benzyl alcohol); avoid with homocystinuria or severe liver disease; compounded sterile-injectable contamination risks1
- Severe skin inflammation and hard nodules where choline injections were given.case report (cited by Healthline)5
- Temporary fishy body odor, attributed to trimethylamine produced from choline and carnitine.community guide3
- Fatigue in the first days, loose stools, increased urination, dizziness and sleep disturbance.anecdotal (community guide)3
- With formulations containing B12, blood B12 levels rising to the top of the normal range, prompting one user's doctor to stop it.anecdotal6
What do peptide guides say about Lipo-C?
- Seek Peptides Seek Peptides explains MIC means methionine, inositol and choline; Lipo-C usually adds L-carnitine and B vitamins, though compounded formulas differ between pharmacies. 3
- Healthline Healthline says any weight lost during lipotropic shots is likely driven by diet and exercise rather than the injections, and many are given in med spas by providers who may not be doctors. 5
- Dr. Axe Dr. Axe notes evidence for L-carnitine, a core Lipo-C ingredient, is mixed: an 8-week trial in obese women found no change in body or fat mass, while a 37-trial analysis found modest reductions. 7
What does the research say, system by system?
Body & tissues1
- Liver (VLDL/triglyceride export via choline-derived phosphatidylcholine)1
Hormones & physiology1
- Inositol component participates in insulin signaling; oral myo-inositol improves insulin sensitivity/ovulation in PCOSoral RCT meta-analyses, not the injection1
Cells & mitochondria1
- Methionine feeds SAMe methylation and glutathione synthesis; L-carnitine (if included) shuttles fatty acids into mitochondria for beta-oxidation (biochemistry)1
Brain, mood & sleep1
- No direct data identified (B12 only relevant if deficient)1
Weight & metabolism1
Also notable1
- Patient-review aggregation of 1,200+ experiences describes mixed, mostly modest resultspractitioner blog/anecdotal9
