What it is
Lipo-C is a lipotropic injection. Lipotropic means fat-moving: it is a mixture of vitamins, nutrients, and amino acids intended to shift how the body handles fat rather than to act like a drug.
Four things are in the vial:
Methionine is an amino acid — one of the building blocks of protein. It supports liver function and fat metabolism, and it feeds the production of glutathione, the body's main built-in antioxidant.
Choline chloride is a nutrient related to the B vitamins. It lets the liver package fat up, move it, and export it, so fat can be transported out of the liver and used elsewhere as energy.
L-carnitine carries fatty acids into the mitochondria — the small structures inside cells that turn fuel into energy — where they are burned to make ATP, the molecule cells actually spend. It has a direct role in fat use.
Dexpanthenol, which is vitamin B5, burns fat at the mitochondrial level and is essential to the metabolism of fatty acids, carbohydrates, and amino acids.
The vial comes ready-mixed. You do not add water and you do not reconstitute anything — you draw a dose out and inject it into a muscle, an intramuscular injection.
Results generally show up fairly quickly, within 2 to 4 weeks.
A pre-mixed lipotropic formulation for intramuscular administration, described as vitamins, nutrients, and branched-chain amino acids that decrease fat deposits, accelerate metabolism, and promote hepatic health, with results generally apparent within 2–4 weeks.
Declared constituents and their stated roles:
Methionine — hepatic function and fat metabolism support; substrate contribution to glutathione synthesis.
Choline chloride — enables hepatic packaging, mobilisation, and export of fat; supports systemic fat utilisation by transporting fat out of the liver for use as energy.
L-carnitine — mitochondrial transport of fatty acids for conversion to ATP; direct role in fat utilisation.
Dexpanthenol (B5) — fat oxidation at the mitochondrial level; essential to fatty acid, carbohydrate, and amino acid metabolism.
Note: the formula is described as containing branched-chain amino acids. Methionine is not a branched-chain amino acid — it is a sulfur-containing one. Nothing in the declared list is a BCAA.
This is the MIC-type lipotropic of the line, and the only one of the four lipotropics on this site with its formulation, side-effect profile, and contraindication declared in full.
What it does
It works on fat in two places at once. Choline moves fat out of the liver so it does not sit there; carnitine carries the fatty acids into the parts of the cell that burn them. Methionine and B5 support the machinery that does the burning.
Alongside that, it is credited with a broad set of effects: preserving muscle tissue, raising metabolism, supporting hormone function, improving liver health, raising energy, lowering cholesterol, helping the immune system, supporting skin, nails, and hair, and supporting detoxification.
Mental effects are also claimed — improved mental clarity, less fatigue, better memory and mood.
One instruction matters here: stay hydrated. Kidney damage is possible if you do not.
Two distinct arms on lipid handling: choline-driven hepatic export of fat (the anti-steatotic arm) and carnitine-driven mitochondrial import of long-chain fatty acids for β-oxidation (the utilisation arm), with methionine and pantothenate supporting the transmethylation and coenzyme-A supply that both depend on.
Claimed effects, in full: muscle tissue preservation and prevention of muscle wasting; reduced body fat; fat metabolism support; raised metabolic rate; support of proper hormone function; improved liver health and promotion of healthy hepatic function; increased energy; lowered cholesterol; improved mental clarity, prevention of fatigue, enhanced memory and mood; immune support; support for skin, nails, and hair; and aid to detoxification with improved digestion, clearer skin, and immune function.
Hydration is an instruction rather than a benefit, and is the counterpart to the side-effect entry for renal damage in the absence of adequate hydration. Treat it as a condition of use, not advice.

Reconstitution and dosing
Storage first, because it matters most: do not store this product in the refrigerator or the freezer. It will gel or crystallise if it gets cold. Keep it between 63 and 77°F, in a dark, dry place.
The vial comes ready-mixed. There is nothing to reconstitute and no bacteriostatic water to add.
Inject into a muscle. Dose in the morning, so it does not disturb your sleep. You do not have to be fasted.
A cycle is at least 8 weeks, followed by a break of at least half the length of the cycle you completed.
The standard dose is 50 to 100 units once a day, 2 to 3 days a week. The advanced dose is 50 to 150 units once a day, 3 to 5 days a week.
Drink water. Kidney damage is a possible side effect if you do not.
About the numbers in the table. The doses are written as "50-100 units (500-1,000mcg)", which means 10 units is 100 micrograms — 1 milligram in every millilitre of solution. The vial size and its milligram content are not specified. The table below uses a placeholder vial of 10 mg in 10 mL purely so the draw column reproduces the unit numbers in the dosing schedule exactly. That milligram figure is a placeholder for the arithmetic, not a fact about the product. Work from the unit numbers.
Storage: never refrigerate or freeze, before or after use — the formulation gels or crystallises. Store at 63–77°F in a dark, dry environment. The LIPO C+ entry attributes this to L-carnitine's crystallisation tendency at high concentration and gives a warm-water-bath recovery procedure that applies to this product too.
Pre-mixed solution; no reconstitution step.
Intramuscular administration. Morning dosing to avoid sleep disturbance. Fasting not required.
Cycle: minimum 8 weeks, washout at least half the completed cycle length.
Standard protocol: 50–100 units 1×/day, 2–3 days per week. Advanced protocol: 50–150 units 1×/day, 3–5 days per week.
Hydration is a condition of use, not an optimisation — renal damage in its absence is listed among the adverse effects.
Concentration basis and disclosure. The dosing pairs 50–100 units with 500–1,000 mcg, implying 10 mcg per insulin unit, i.e. 1 mg/mL. No vial volume or vial mass is specified. The protocols below carry a derived placeholder of 10 mg in 10 mL, chosen solely to reproduce the stated unit figures exactly at the implied concentration. The concentration is fixed by the dosing figures; the vial mass and volume are not.
Plausibility note: 1 mg/mL of total solute is one to three orders of magnitude below what a clinical MIC-type lipotropic runs at, and the microgram figures are most likely a convention rather than a measurement. The unit figures are the ones to work from; they are internally consistent across all four lipotropics on this site.
Standard protocol
Supplied as a ready-mixed solution — nothing to reconstitute. No vial size or mass is specified; the 10 mg in 10 mL shown here is a placeholder that reproduces the figure of 10 mcg per insulin unit, so the draw column matches the dosing schedule exactly. Never refrigerate or freeze; store at 63–77°F, dark and dry.
1 mg/mL · 10 mcg per unit
Cycle: Minimum 8 weeks, then a washout of at least half the cycle length · Frequency: 1×/day, 2–3 days per week; intramuscular; morning; fasting not required
| When | Dose | Draw | How often |
|---|---|---|---|
| 50 units — low end of the 50–100 unit range | 500 mcg | 50 units | 1×/day, 2–3 days per week |
| 100 units — top of the range | 1 mg | 100 units | 1×/day, 2–3 days per week |
Advanced protocol
Ready-mixed solution; no reconstitution. The 10 mg in 10 mL is a placeholder reproducing the stated 10 mcg per insulin unit — no vial size or mass is specified. Never refrigerate or freeze.
1 mg/mL · 10 mcg per unit
Cycle: Minimum 8 weeks, then a washout of at least half the cycle length · Frequency: 1×/day, 3–5 days per week; intramuscular; morning; fasting not required
| When | Dose | Draw | How often |
|---|---|---|---|
| 50 units — low end of the 50–150 unit range | 500 mcg | 50 units | 1×/day, 3–5 days per week |
| 150 units — top of the range | 1.5 mg | 150 units(over 100 units: split across 2 syringes) | 1×/day, 3–5 days per week |
10 mg in 10 mL is 1 mg/mL, or 10 mcg per unit. Draw 50 units (0.5 mL) for 500 mcg.
Who should avoid it
- Anyone allergic to any of the components of the product. That is the only documented contraindication.
- Signs of an allergic reaction: rash, hives, or itchiness.
- Signs of an allergic reaction: shortness of breath.
- Signs of an allergic reaction: chest tightness.
- Signs of an allergic reaction: swelling of the throat, lips, mouth, or tongue.
- No drug interactions have been documented for Lipo-C.
- Note: no data on pregnancy and breastfeeding are available for Lipo-C. The LIPO C+ page, which shares three of these four ingredients, excludes both outright.
- Note: no guidance on liver disease is available either. LIPO C+ warns about the load lipotropics place on the liver in people with liver disease, and the same reasoning would apply to this formula.
- Hypersensitivity to any constituent — the only contraindication stated.
- Hypersensitivity presentation: rash, urticaria, pruritus.
- Hypersensitivity presentation: dyspnoea.
- Hypersensitivity presentation: chest tightness.
- Hypersensitivity presentation: angioedema of the throat, lips, mouth, or tongue.
- No drug interactions have been documented.
- Note: pregnancy and lactation are unaddressed for Lipo-C, while the LIPO C+ page — sharing methionine, choline, and L-carnitine — contraindicates both.
- Note: hepatic impairment is unaddressed for Lipo-C. LIPO C+ flags methylation and hepatic load as a caution in liver disease, and the shared constituents carry that load identically.
- Note: the standalone L-Carnitine page on this site contraindicates cardiovascular disease, arrhythmia, uncontrolled hypertension, stimulant sensitivity, anxiety or panic disorder, epilepsy, and pregnancy or lactation, and lists interactions with thyroid replacement and with glucose-lowering drugs. L-carnitine is a declared constituent here at an undisclosed dose, so how much of that transfers is not determinable — but the absence of such warnings for Lipo-C is not evidence that none of it does.
Side effects
- Reaction where you inject — redness, swelling, itching, infection, scarring.
- Nausea.
- Urinary problems.
- Fatigue.
- Constipation.
- Numbness in the feet or hands.
- Excessive sweating or excessive salivation.
- Kidney damage, if you do not stay properly hydrated. This is why staying hydrated is an instruction, not a suggestion.
- Fatigue immediately after the injection, which usually resolves quickly.
- Injection site reaction: erythema, swelling, pruritus, infection, scarring.
- Nausea.
- Urinary disturbance.
- Fatigue.
- Constipation.
- Paraesthesia of the feet or hands.
- Excessive sweating or salivation.
- Renal damage in the absence of adequate hydration — stated without qualification, and it is what the hydration instruction is there for.
- Immediate post-injection fatigue, typically self-limiting.
- Note: peripheral numbness on a methionine- and B-vitamin-containing preparation is worth watching rather than tolerating, since it is also the presentation of pyridoxine excess and of B12 deficiency. No monitoring guidance has been established.

Stacking
- GLP-1 agonists
Lipo-C is paired with the GLP medications for amplified fat loss and appetite suppression. GLP-1 agonists are the class that includes semaglutide and tirzepatide.
Suggested for amplified fat loss and appetite suppression. Note that GLP-1 receptor agonists are themselves associated with B12 depletion, which is why the B12 page suggests the reverse pairing.
Suggested for full-spectrum body recomposition — losing fat and building lean tissue at the same time rather than one or the other.
Suggested for full-spectrum recomposition: pairing a hepatic/mitochondrial fat-handling adjunct with a GHRH analogue that drives visceral lipolysis.
The other recomposition suggestion, alongside Tesamorelin.
Suggested for full-spectrum recomposition, grouped with Tesamorelin — growth hormone axis stimulation alongside the lipotropic arm.
Paired here for extra energy and mood stabilisation. The B12 entry makes the same pairing from its own side.
Reciprocal suggestion — the B12 entry lists MIC+C (Lipo-C) for fat metabolism, hepatic detoxification, and energy. Note that B5 is already in this formula but B12 is not.
One of the four ingredients already in this vial, also sold on its own. Worth reading, because the standalone L-carnitine entry has a list of contraindications and interactions that are not repeated here.
A declared constituent here at an undisclosed dose. The standalone entry carries the contraindication and interaction set — cardiovascular disease, arrhythmia, uncontrolled hypertension, epilepsy, thyroid replacement, glucose-lowering agents — that is not documented for Lipo-C. Read it before stacking additional carnitine on top of an already carnitine-containing formula.
