L-Carnitine dosage chart
200 mg Vial
L-Carnitine is dosed at 50 mg–100 mg daily via subcutaneous injection in educational protocols. A 200 mg vial reconstituted with bacteriostatic water yields about 100 mg/mL. This information is for research and educational use only.
- Reconstitute
- Add 2.0 mL bacteriostatic water → 100 mg/mL concentration (1 unit = 1 mg).
- Typical daily range
- 50–100 mg once daily (gradual titration); advanced protocols may use up to 200 mg.
- Easy measuring
- At 100 mg/mL, 1 unit = 0.01 mL = 1 mg on a U-100 insulin syringe.
- Storage
- Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) and use within 2–4 weeks; do not freeze reconstituted solution.
- Injection frequency
- Once daily — 5 days on, 2 days off (dose Mon–Fri, rest Sat–Sun).
- Dosing schedule
- 5 days on / 2 days off: dose Monday through Friday, then take Saturday and Sunday off. That is 5 dosing days per week.
Dosing Cycle & Timing
This protocol runs on a 5 days on / 2 days off cycle.
- Cycle: 5 days on, 2 days off — dose Monday through Friday and rest on the weekend.
- 5 dosing days per week; the 2 off days help limit receptor desensitisation and give injection sites time to recover.
- Keep the dose time consistent on dosing days.
- If a weekday dose is missed, take it the same day if possible — do not dose on an off day to catch up.
- Weekly totals in the supplies and shopping lists are calculated on 5 dosing days, not 7.
Supplies needed
Plan covers the full 8-week protocol at the lowest listed starting dose: 100 mg per dose, 5 days on / 2 days off (40 administrations in total), using 200 mg vials. After mixing with 2 mL, the concentration is 100 mg/mL and each dose requires 1 mL total.
L-Carnitine vials (200 mg each)
Vials are rounded up only after calculating the whole protocol: ceil(4000 ÷ 200) = 20. Usable peptide remaining in an opened vial carries forward to the next dose.
- Full protocol (8 weeks)
- 20 vials (4000 mg needed ÷ 200 mg)
Insulin syringes (U-100, 1 mL)
One fresh syringe per administration.
- Full protocol (8 weeks)
- 40 syringes
Bacteriostatic water (10 mL bottles)
Use 2 mL per vial for reconstitution (20 × 2 mL = 40 mL).
- Full protocol (8 weeks)
- 4 × 10 mL bottles
Alcohol swabs
One for the vial stopper per draw + one for each injection site (5 days on / 2 days off). Recommend 1 × 100-count box.
- Full protocol (8 weeks)
- 80 swabs

L-Carnitine dosage FAQs
How much bacteriostatic water do you use to reconstitute L-Carnitine?
Add 2.0 mL bacteriostatic water → 100 mg/mL concentration (1 unit = 1 mg). for a 200 mg Vial vial. Add the water slowly against the inside wall of the vial and swirl — never shake — until the powder fully dissolves.
How often is L-Carnitine administered in research protocols?
Injection frequency: Once daily — 5 days on, 2 days off (dose Mon–Fri, rest Sat–Sun).
How should reconstituted L-Carnitine be stored?
Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) and use within 2–4 weeks; do not freeze reconstituted solution..
How many insulin syringe units equal a L-Carnitine dose?
Units depend on the water volume you used. Divide your target dose by the vial concentration to get millilitres, then multiply by 100 — 1 unit on a U-100 insulin syringe is 0.01 mL. The Spartan Peptides reconstitution calculator does this conversion for you.
Is L-Carnitine approved for human use?
No. L-Carnitine is sold and referenced strictly as a research chemical. Nothing on this page is medical advice and the material is not for human consumption.
Educational and research information only. Not medical advice, not for human consumption. Values are reference figures — always verify your own math with the reconstitution calculator.
On any insulin syringe, 1 unit = 0.01 mL, so unit counts above hold across brands.
