How much Lipo-C to inject per week: most people run 0.5 to 2 mL, one to three times weekly, on the standard 15/50/50/5 mg/mL compounded strength. On a U-100 insulin syringe that is 50 to 200 units per shot. The most-reported starting protocol in this community is 1 mL, twice weekly. The full chart, the units conversion, per-day and female protocols, and a dose calculator are below.

Lipo-C has been discussed on ExcelMale since 2016. Hundreds of members have posted protocols, results, and side effects across that time. This guide pulls that experience together with published clinician ranges so you get one clear answer to how much, how often, and whether it does anything.
Lipo-C is supportive metabolic therapy, not a primary fat-loss drug. It earns its place as an adjunct: alongside a calorie deficit, TRT, or GLP-1 therapy. Here is what the evidence and the community say about getting the dose right.
There is no FDA-approved dose for Lipo-C. The protocols below come from Empower Pharmacy, Defy Medical, clinical spa protocols, and ExcelMale community reports.
Community consensus starting point: the most-reported protocol across years of ExcelMale threads is 1 mL, 2–3 times per week, SQ or IM. Members who notice a subjective benefit usually report it within 2 to 4 weeks. If nothing has changed by week 3, the common next step is 2 mL or a move to daily 1 mL before deciding it does not work for you.
The single most common dosing question is how mL maps to the units marked on an insulin syringe. On any U-100 syringe the scale is fixed: 1.0 mL is 100 units, regardless of whether the barrel is a 0.3, 0.5, or 1 mL syringe.
mg values use the standard 50 mg/mL carnitine and choline concentration. Confirm your own vial, since compounders vary.
Most protocols are two or three times a week, not daily. Some users prefer a daily 1 mL subcutaneous dose to hold carnitine and B-vitamin levels steadier and to smooth out the energy effect. Daily use is a preference, not a requirement, and it burns through a vial about three times faster. If you go daily, keep the single dose at 1 mL SQ, rotate sites, and use the morning so the B-vitamin stimulation does not affect sleep. There is no reported advantage to daily dosing over 2–3× weekly for fat loss specifically; the case for daily is energy consistency.
The formulation does not change by sex. What differs in practice is starting volume and titration speed, since women in these programs often start at a lower body weight and report more injection-site sensitivity at the top of the range.
Most women in the community threads land on 50 units twice weekly and adjust from there. Pregnancy and breastfeeding are stopping points: concentrated methyl-donor combinations are not well studied in pregnancy, and guidance is to avoid Lipo-C unless a clinician judges maternal benefit to outweigh theoretical risk under obstetric supervision.

Lipo-C is a compounded injectable that combines lipotropic agents (compounds that move fat out of the liver) with amino acids and cofactors that support fat metabolism and energy. It is prescription-only and compounded by pharmacies including Empower Pharmacy and Defy Medical. "Lipotropic" means fat-moving: these compounds help keep fat from accumulating in the liver, support bile production, and improve how efficiently stored fat is converted to energy.
Lipo-B vs Lipo-C. Empower's Lipo-B (MIC) is methionine, choline, and B12. Lipo-C drops the standalone B12 focus and adds L-carnitine, the fatty-acid transporter, making it the broader-spectrum metabolic formulation and the more commonly prescribed of the two for fat-loss support. Formulas differ by compounder, so the exact contents on your label are what matter.
Standard Empower Lipo-C: Methionine 15 mg/mL, Choline chloride 50 mg/mL, L-Carnitine 50 mg/mL, Dexpanthenol (B5) 5 mg/mL, in water for injection. Some compounders add inositol, B12, thiamine, or pyridoxine.
Compounding variability: Lipo-C is not standardized across pharmacies. Concentrations, added vitamins, and beyond-use dates differ. Defy's version, for example, uses thiamine (B1) where Empower uses carnitine as the headline addition. Confirm your exact mg/mL composition before setting a dose.
Weeks 1–2: start at 0.5–1 mL, 1–2× per week. Watch tolerance: odor, injection-site reactions, GI changes.
Weeks 3–6: if tolerated, move to 1 mL, 2–3× per week. This is where most users settle.
Week 6+: if energy or fat-loss response is minimal, try 2 mL IM 2× per week, or daily 1 mL SQ.
Reassess at 12–16 weeks: if there is no measurable or subjective benefit, reconsider whether Lipo-C is the right tool for you.
Subcutaneous (SQ). Use a 1/2-inch insulin syringe, 28–31g. Best sites are pinched abdominal fat and outer thigh. Inject at 45 degrees into the pinched fold. Keep SQ volume at or below 1 mL per site, since larger volumes leave firm, slow-absorbing lumps.
Intramuscular (IM). Use a 5/8-inch, 25–26g needle. Best sites are the vastus lateralis (outer thigh), ventroglute, or dorsoglute. IM suits volumes above 1 mL and absorbs faster. Aspirate slightly to confirm you are not in a vessel before injecting.
The odor effect. Choline and carnitine breakdown, plus any added B12, can produce a sulfur or "fishy" smell in sweat, urine, or breath within hours of a shot. It is harmless and usually fades within a day or two. Intensity varies by formulation and individual metabolism.
Lipo-C + B12. Some compounders build B12 into the formula, others supply it separately. If yours does not include B12, a separate 1–2× weekly B12 injection is worth considering for energy. Many members report B12 as the component they feel most directly.
Lipo-C + GLP-1 agonists (semaglutide, tirzepatide). This is the fastest-growing use case. GLP-1s drive aggressive caloric restriction, which accelerates lean-muscle loss and can impair liver fat clearance. Lipo-C is co-prescribed to hold L-carnitine levels during that deficit, support hepatic fat mobilization as lipid flux rises, and partly offset GLP-1 fatigue through B-vitamin and carnitine support. No pharmacokinetic conflict is known; the two are usually injected at different times of day. Confirm the combination with your provider.
Lipo-C + TRT. TRT improves insulin sensitivity and lipid metabolism but does not directly clear hepatic fat. For men on TRT in a fat-loss phase, Lipo-C adds complementary support, and L-carnitine has independent literature backing for improving lipid profiles in men on testosterone.
Most reactions are mild: injection-site soreness, warmth, or redness that fades quickly, and the transient odor effect above. Uncommon but real: GI upset, and rare hypersensitivity. In one retrospective series of over 2,000 compounded lipotropic injections, systemic hypersensitivity ran below 0.1 percent. Absolute contraindications include hypersensitivity to any component, severe hepatic failure, and sulfur-amino-acid disorders such as homocystinuria. Renal or hepatic impairment calls for extra caution, since carnitine clears renally and methionine loads the liver.
Storage: refrigerate at 36–46°F, keep away from light, do not freeze. Most compounded vials carry a 28–30 day beyond-use date after dispensing.
It depends what you ask it to do. Each component (L-carnitine, choline, methionine) has legitimate mechanistic data behind it for fat metabolism and liver function. In meta-analyses, L-carnitine produces modest but statistically real reductions in body weight, and it does that by moving fatty acids into mitochondria for oxidation. That effect only shows up when there is a calorie deficit and activity for it to act on. Members who report the clearest results pair Lipo-C with a deficit and training, or run it alongside GLP-1 therapy. Standalone results without diet change are modest at best.
How much Lipo-C should I inject?
Most protocols start at 0.5–1 mL (50–100 units) SQ or IM, 1–3 times per week, titrated up to 2 mL depending on tolerance and goals. Keep any single SQ dose at or below 1 mL to avoid lumps. Most users settle at 1 mL, 2–3× weekly.
How much Lipo-C per week?
Common weekly totals run 1 to 3 mL. A typical maintenance week is 1 mL twice (2 mL total). Aggressive phases reach 4 mL a week under supervision.
How do mL convert to units?
On a U-100 insulin syringe, 1 mL is 100 units, so 0.5 mL is the 50-unit mark and 0.25 mL is 25 units.
Can I stack Lipo-C with semaglutide or tirzepatide?
Yes, and it is increasingly common. Lipo-C is used to support liver health, hold carnitine levels, and reduce GLP-1 energy crashes during aggressive restriction. No known pharmacokinetic conflict. Confirm with your provider.
How often should I inject Lipo-C?
Most protocols use 2–3× per week. Some run daily 1 mL SQ for steadier levels; weekly dosing is for maintenance. Start at 2× per week before increasing.
Does Lipo-C work for fat loss?
As supportive therapy, yes; as a standalone fat burner, not meaningfully. Best results come with a calorie deficit and training, or alongside GLP-1 therapy.
What is the difference between Lipo-B and Lipo-C?
Empower's Lipo-B is methionine, choline, and B12. Lipo-C adds L-carnitine and additional B vitamins and is the broader metabolic formula.
Where do you inject Lipo-C?
SQ into pinched belly fat or outer thigh with a 1/2-inch insulin syringe, or IM into glutes or vastus lateralis with a 5/8-inch 25–26g needle. Use IM for volumes above 1 mL.
How long does a 30 mL vial last?
At 1 mL three times a week, about 10 weeks. At 1 mL twice a week, about 15 weeks. At daily 1 mL, about 4 weeks. Beyond-use date is usually 28–30 days after dispensing, so daily users may not finish a 30 mL vial before it expires. Typical cost is $76–100 per 30 mL vial.

mL to units: reading your syringe
The single most common dosing question is how mL maps to the units marked on an insulin syringe. On any U-100 syringe the scale is fixed: 1.0 mL is 100 units, regardless of whether the barrel is a 0.3, 0.5, or 1 mL syringe.
| Volume | Units (U-100 mark) | L-Carnitine | Choline |
|---|---|---|---|
| 0.25 mL | 25 units | 12.5 mg | 12.5 mg |
| 0.5 mL | 50 units | 25 mg | 25 mg |
| 1.0 mL | 100 units | 50 mg | 50 mg |
| 1.5 mL | 150 units | 75 mg | 75 mg |
| 2.0 mL | 200 units | 100 mg | 100 mg |
mg values use the standard 50 mg/mL carnitine and choline concentration. Confirm your own vial, since compounders vary.

|---|---|---|---|---|
| Starter / sensitive | 0.5 mL | 50 units | 1× / week | 0.5 mL |
| Standard | 0.5 mL | 50 units | 2× / week | 1.0 mL |
| Active phase | 1.0 mL | 100 units | 2× / week | 2.0 mL |
Most women in the community threads land on 50 units twice weekly and adjust from there.

Formulas differ by compounder, so the exact contents on your label are what matter.
Ingredients and what each does
Standard Empower Lipo-C: Methionine 15 mg/mL, Choline chloride 50 mg/mL, L-Carnitine 50 mg/mL, Dexpanthenol (B5) 5 mg/mL, in water for injection. Some compounders add inositol, B12, thiamine, or pyridoxine.
| Ingredient | Conc. | Role |
|---|---|---|
| L-Carnitine | 50 mg/mL | Shuttles long-chain fatty acids into mitochondria for oxidation. The most evidence-backed component for metabolic support. |
| Choline chloride | 50 mg/mL | Substrate for phosphatidylcholine and bile production. Helps prevent fat accumulation in the liver. |
| Methionine | 15 mg/mL | Sulfur amino acid and methyl donor for SAMe synthesis. Supports fat export from hepatocytes. |
| Dexpanthenol (B5) | 5 mg/mL | Converted to coenzyme A, required for fat and carbohydrate metabolism. |
| Inositol | Varies | Insulin-sensitizing, supports liver fat metabolism. Common in MIC formulas, not in every Lipo-C. |
| Cyanocobalamin (B12) | Varies | Supports red-cell production, methylation, and nerve function. Often the component behind the energy effect users report. |
Compounding variability: Lipo-C is not standardized across pharmacies. Concentrations, added vitamins, and beyond-use dates differ. Defy's version, for example, uses thiamine (B1) where Empower uses carnitine as the headline addition. Confirm your exact mg/mL composition before setting a dose.
Titration: how to ramp
Weeks 1–2: start at 0.5–1 mL, 1–2× per week. Watch tolerance: odor, injection-site reactions, GI changes.
Weeks 3–6: if tolerated, move to 1 mL, 2–3× per week. This is where most users settle.
Week 6+: if energy or fat-loss response is minimal, try 2 mL IM 2× per week, or daily 1 mL SQ.
Reassess at 12–16 weeks: if there is no measurable or subjective benefit, reconsider whether Lipo-C is the right tool for you.
How to inject: sites, needles, technique
Subcutaneous (SQ). Use a 1/2-inch insulin syringe, 28–31g. Best sites are pinched abdominal fat and outer thigh. Inject at 45 degrees into the pinched fold. Keep SQ volume at or below 1 mL per site, since larger volumes leave firm, slow-absorbing lumps.
Intramuscular (IM). Use a 5/8-inch, 25–26g needle. Best sites are the vastus lateralis (outer thigh), ventroglute, or dorsoglute. IM suits volumes above 1 mL and absorbs faster. Aspirate slightly to confirm you are not in a vessel before injecting.
The odor effect. Choline and carnitine breakdown, plus any added B12, can produce a sulfur or "fishy" smell in sweat, urine, or breath within hours of a shot. It is harmless and usually fades within a day or two. Intensity varies by formulation and individual metabolism.
Stacking: B12, GLP-1s, and TRT
Lipo-C + B12. Some compounders build B12 into the formula, others supply it separately. If yours does not include B12, a separate 1–2× weekly B12 injection is worth considering for energy. Many members report B12 as the component they feel most directly.
Lipo-C + GLP-1 agonists (semaglutide, tirzepatide). This is the fastest-growing use case. GLP-1s drive aggressive caloric restriction, which accelerates lean-muscle loss and can impair liver fat clearance. Lipo-C is co-prescribed to hold L-carnitine levels during that deficit, support hepatic fat mobilization as lipid flux rises, and partly offset GLP-1 fatigue through B-vitamin and carnitine support. No pharmacokinetic conflict is known; the two are usually injected at different times of day. Confirm the combination with your provider.
"Started semaglutide at 1 mg/week and felt completely wiped out by week 3. My doc added Lipo-C 1 mL 3x/week and the energy crash improved noticeably within 2 weeks. Not sure which component is doing the work but something is."

Lipo-C + TRT. TRT improves insulin sensitivity and lipid metabolism but does not directly clear hepatic fat. For men on TRT in a fat-loss phase, Lipo-C adds complementary support, and L-carnitine has independent literature backing for improving lipid profiles in men on testosterone.
Side effects and storage

"It's not a magic fat burner. But when I'm dieting hard and training, it genuinely seems to blunt the fatigue and help me recover faster. I've run it on and off for two years. Keep coming back to it."
