L-Carnitine (200mg Vial) Dosage Protocol
Quickstart Highlights
L-Carnitine 200mg dosage protocol supports fat metabolism, recovery, and energy production through Sub-Q or IM injections.
- Typical starting dose: 100 mg 2–3 × per week
- Performance phases may reach 200-400 mg daily
- Reconstitute with 1 mL (200 mg/mL) for standard use
- Advanced users can reconstitute with 0.5 mL (400 mg/mL) for higher dosing
- Store lyophilized vials frozen; refrigerate after reconstitution

Dosing & Reconstitution Guide
Educational guide for reconstitution and dosing protocol
Standard / Gradual Approach (1 mL = 200 mg/mL)
Week | Dosage | Units (mL) |
---|---|---|
Weeks 1–4 | 100 mg, 2 ×/wk | 50 u (0.5 mL) |
Weeks 5–8 | 100 mg, 3 ×/wk | 50 u (0.5 mL) |
Weeks 9–12 | 120 mg, 3 ×/wk | 60 u (0.6 mL) |
Weeks 13–16 (Optional) | 150 mg, 3 ×/wk | 75 u (0.75 mL) |
Ideal for general metabolic support and weight-management programs. Reconstitute each vial with 1 mL bacteriostatic water (200 mg/mL). Injections >60 u may be divided into two sites for comfort.
- Draw 1.0 mL bacteriostatic water into a sterile syringe.
- Inject slowly along the vial wall; swirl gently to dissolve.
- Label vial with concentration & date; refrigerate 2–8 °C.
Advanced / Aggressive Approach (0.5 mL = 400 mg/mL)
Week | Dosage | Units (mL) |
---|---|---|
Weeks 1–4 | 200 mg, daily | 50 u (0.5 mL) |
Weeks 5–8 | 300 mg, daily | 75 u (0.75 mL) |
Weeks 9–12 | 400 mg, daily | 100 u (1.0 mL) |
Weeks 13–16 (Optional) | 500 mg, daily | 125 u (1.25 mL) |
Suited for athletes or intensive recovery phases. Reconstitute with 0.5 mL to create a 400 mg/mL solution. Doses >60 u may require two injections/site rotation.
- Add 0.5 mL bacteriostatic water slowly into the vial.
- Swirl gently until clear; avoid shaking.
- Store refrigerated (2–8 °C).
Protocol Overview
Concise summary for both standard and high-performance applications.
- Goals: Enhance fat oxidation, improve recovery, boost endurance
- Schedule: 2–3 × weekly (standard) or daily (advanced)
- Dose Range: 100 mg to 500 mg per injection
- Reconstitution: 1 mL (standard) or 0.5 mL (advanced)
- Storage: Freeze lyophilized; refrigerate reconstituted
Dosing Protocol
Select the schedule below that aligns with your research objective.
- Standard: 100 mg 2–3 × weekly for 12–16 weeks
- Advanced: 200–500 mg daily for 8–12 weeks
- Injection Route: Sub-Q or IM; rotate sites
- Split Large Volumes: Divide >60 u into 2 injections
Storage Instructions
Proper storage preserves peptide integrity.
- Lyophilized: –20 °C until reconstitution
- Reconstituted: 2–8 °C; use within 30 days
- Avoid direct light and repeated freeze-thaw cycles
Supplies Needed
Estimate based on standard (100 mg 3 ×/wk) and advanced (400 mg daily) schedules:
- Peptide Vials:
• 8 wks ≈ 8–20 vials
• 12 wks ≈ 12–30 vials
• 16 wks ≈ 16–40 vials
(Higher end reflects advanced dosing) - Insulin Syringes:
• 8 wks ≈ 24–56
• 12 wks ≈ 36–84
• 16 wks ≈ 48–112 - Bacteriostatic Water: 1 × 30 mL bottle (more for large-scale studies)
- Alcohol Swabs: 1 box
Important Notes
Practical tips to enhance safety and accuracy.
- Use sterile syringes; rotate Sub-Q/IM sites to prevent irritation.
- Split injections >60 u into two sites for comfort.
- Monitor for mild GI upset or fishy odor—reduce dose if needed.
- For research purposes only—consult professionals for guidance.
How This Works
L-Carnitine shuttles long-chain fatty acids into mitochondria for beta-oxidation, supporting ATP production.
- Lipid Transport: Moves fatty acids across the mitochondrial membrane
- Energy Support: Increases fat utilization and spares muscle glycogen
- Recovery Aid: Reduces exercise-induced muscle damage and soreness
Potential Benefits & Side Effects
Research observations—individual outcomes may vary.
- Supports fat metabolism and weight-management strategies
- Enhances endurance and reduces fatigue during training
- May improve recovery and reduce muscle soreness
- Mild side effects: GI discomfort, fishy body odor, injection-site redness
Lifestyle Factors
Complementary strategies for optimal research outcomes.
- Adopt a balanced, nutrient-dense diet with adequate protein
- Incorporate consistent aerobic & resistance training
- Prioritize sleep and stress management for recovery
Injection Technique
Simple guidelines for safe daily injections.
- Clean vial rubber stopper & injection site with alcohol swabs
- Insert needle at a 45–90° angle into subcutaneous tissue
- Inject slowly & rotate sites (abdomen, thigh, etc.)
