L-Carnitine (200 mg Vial) Dosage Protocol
L-Carnitine is an amino acid derivative essential for fatty acid transport into mitochondria for β-oxidation. Subcutaneous administration bypasses intestinal conversion to TMAO (linked to cardiovascular risk) and provides 100% bioavailability compared to 5–18% for oral dosing.

Dosing & Reconstitution Guide
Educational guide for reconstitution and daily dosing
Standard / Gradual Approach (2.0 mL = 100 mg/mL)
| Week | Daily Dose | Units (per injection) (mL) |
|---|---|---|
| Weeks 1–2 | 50 mg | 50 units (0.50 mL) |
| Weeks 3–8 | 100 mg | 100 units (1.0 mL) |
| Weeks 9–12 | 100 mg | 100 units (1.0 mL) |
Frequency: Inject once daily subcutaneously. This 2.0 mL reconstitution provides optimal concentration for convenient dosing: 100 mg maintenance dose = exactly 1.0 mL (100 units). For advanced protocols requiring 150–200 mg daily, doses above 1.0 mL may be split into two injections at different sites to improve comfort.
Reconstitution Steps
- Draw 2.0 mL bacteriostatic water (0.9% benzyl alcohol) with a sterile syringe.
- Inject slowly down the vial wall to minimize foaming; avoid direct stream onto powder.
- Gently swirl or roll the vial until powder is fully dissolved (do not shake vigorously).
- Label vial with reconstitution date and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light. Bacteriostatic water does not establish a universal use-by period; follow the exact product’s handling instructions.

Supplies Needed
Plan based on an 8–16 week daily protocol using 100 mg maintenance dose (most common). If starting with 50 mg titration (Weeks 1–2), subtract ~3–4 vials from totals below.
| Item | Quantity |
|---|---|
| Peptide Vials (L-Carnitine, 200 mg each) | 8 weeks (56 days @ 100 mg/day) ≈ 28 vials 12 weeks (84 days @ 100 mg/day) ≈ 42 vials 16 weeks (112 days @ 100 mg/day) ≈ 56 vials |
| Insulin Syringes (U-100, 1 mL capacity) | Per week: 7 syringes (1/day) 8 weeks: 56 syringes 12 weeks: 84 syringes 16 weeks: 112 syringes |
| Bacteriostatic Water (10 mL bottles) | 8 weeks (28 vials): 56 mL → 6 × 10 mL bottles 12 weeks (42 vials): 84 mL → 9 × 10 mL bottles 16 weeks (56 vials): 112 mL → 12 × 10 mL bottles |
| Alcohol Swabs | Per week: 14 swabs (2/day) 8 weeks: 112 swabs → recommend 2 × 100-count boxes 12 weeks: 168 swabs → recommend 2 × 100-count boxes 16 weeks: 224 swabs → recommend 3 × 100-count boxes |
Each 200 mg vial prepared at 2.0 mL provides two 100 mg amounts or four 50 mg amounts.
Sharps Container: For safe disposal of used syringes and needles.
Storage Instructions
| State | Temperature | Duration |
|---|---|---|
| Lyophilized | −20°C (−4°F) | Up to 24 months, dry & dark |
| Reconstituted | 2–8°C (35–46°F) | Up to 28 days, protect from light |
Important Notes
How This Works
L-Carnitine acts as an obligate cofactor for the carnitine palmitoyltransferase (CPT) enzyme system, which shuttles long-chain fatty acids across the inner mitochondrial membrane for β-oxidation and ATP production. Subcutaneous route bypasses gut bacterial conversion to trimethylamine-N-oxide (TMAO), the metabolite linked to elevated cardiovascular risk with oral dosing.
Potential Benefits & Side Effects
Potential Benefits
- Enhanced mitochondrial fatty acid oxidation.
- Modest weight loss in meta-analysis (~1.2 kg).
- Reduced fatigue in dialysis populations.
- Bypasses TMAO production associated with oral dosing.
- Well-tolerated at parenteral doses up to 50 mg/kg IV daily.
Side Effect Profile
- Mild injection-site reactions (typically transient).
- Oral high doses (>3 g) cause fishy body odor — subcutaneous minimizes this.
Lifestyle Factors
- Protein-forward diet with adequate lysine and methionine.
- Combine resistance + aerobic training for fat oxidation synergy.
- Modest caloric deficit (300–500 kcal/day) for fat-loss goals.
Injection Technique
- Subcutaneous, rotate sites.
- Warm vial to room temp before injection to reduce pain.
- Volumes >1 mL: split into 2 injections.
