Injectable L-Carnitine
Also known as: L-Carnitine Injection, Levocarnitine
Injectable L-Carnitine bypasses the poor oral bioavailability of carnitine supplements to deliver supraphysiological levels directly into muscle tissue. L-Carnitine plays an essential role in transporting long-chain fatty acids into mitochondria for beta-oxidation. The injectable form is favored in bodybuilding for its superior absorption.

| Class | Other |
| Category | Fat Loss Agents |
Mechanism of Action
L-Carnitine shuttles long-chain fatty acids across the inner mitochondrial membrane via the carnitine palmitoyltransferase (CPT) system for beta-oxidation. Supraphysiological levels may enhance fat oxidation capacity, improve exercise performance, and reduce markers of muscle damage. Injectable administration achieves plasma levels far exceeding what oral supplementation can provide.
Dosing Research
Typical dose: 500-2000 mg injected intramuscularly or subcutaneously, 3-5 times per week. Oral carnitine bioavailability is only 5-18%, making injection the preferred route for performance use. No cycling typically required. Injection site rotation recommended.
Side Effects & Risks
Injection site pain, swelling, and irritation. Fishy body odor at high doses (due to trimethylamine). Nausea and GI discomfort (more common with oral). Generally very safe. Rare allergic reactions. Some concern about TMAO production and cardiovascular risk with chronic high-dose use.
