Methionine + Choline + L-Carnitine + Dexpanthenol calculator
A compounded 'lipotropic' injection blend of nutrients marketed for weight loss. Evidence for meaningful fat loss is weak.
Also known as: Lipotropic injection blend, Lipo injection
FDA status — not an approved drug The individual ingredients are nutrients, not FDA-approved for weight loss. Compounded lipotropic blends are not reviewed by FDA for safety, effectiveness, or quality.
This draw does not fit the selected syringe.1000000 units exceeds the 100-unit barrel. Choose a larger syringe, use less bacteriostatic water, or split the dose.

What Methionine + Choline + L-Carnitine + Dexpanthenol is
Lipotropic injections are compounded blends of nutrients — classically methionine, inositol, and choline, often with carnitine, dexpanthenol, or B vitamins — marketed to support fat metabolism and weight loss. They are a longstanding offering of weight-loss clinics, but rigorous evidence for fat loss is lacking.
Research depth: 2/5 The individual nutrients are well characterized, but the blend has little controlled evidence for weight loss. Human trials: None for the combination. This measures how much has been studied — counting animal and laboratory work — not whether it works for you.
How Methionine + Choline + L-Carnitine + Dexpanthenol works
The ingredients are cofactors in lipid metabolism: choline and methionine support phospholipid synthesis and methyl donation, and carnitine shuttles fatty acids into mitochondria. The theory is that supplying them aids fat processing. In people who are not deficient, controlled trials have not shown that injecting these produces meaningful weight loss.
Methionine + Choline + L-Carnitine + Dexpanthenol side effects
Commonly reported
- Injection-site pain or irritation
- Nausea or stomach upset
- Fishy body odor with high choline intake
Serious — seek medical care
- Allergic reactions to components
- Interactions or dosing errors with compounded multi-ingredient products
- Evidence for efficacy is weak — the main risk is paying for an unproven treatment
This list is not exhaustive. Report anything unexpected to the clinician who prescribed it. If you have severe abdominal pain, trouble breathing, or signs of an allergic reaction, seek care the same day. See also our guide to peptide side effects by class.
A worked example
A 10 mg vial reconstituted with 10 mL of bacteriostatic water gives 1 mg/mL. A 10000000 mcg dose is then 10000 mL — about 1000000 units on a 100-unit insulin syringe, giving roughly 0 doses per vial before accounting for residual volume left in the vial and syringe.

Commonly cited dose range
Figures circulating for Methionine + Choline + L-Carnitine + Dexpanthenol run from 5000000 mcg to 15000000 mcg. These blends are dosed in milliliters of the combined solution rather than by a single active amount. Figures shown are total milligrams per typical vial, in micrograms. Dosing follows the compounding pharmacy's labeling.

Common questions
Do lipotropic injections work for weight loss?
Controlled evidence for meaningful weight loss from lipotropic injections is weak. Any benefit seen in practice is generally attributable to the accompanying diet and activity changes, not the injection itself.
What's in a lipotropic blend?
Typically methionine, inositol, choline, and often B vitamins or carnitine — nutrients involved in fat metabolism. The exact recipe varies by compounding pharmacy.
