L-Carnitine (200 mg Vial) Dosage Protocol

Quickstart Highlights

L-Carnitine is an amino acid derivative essential for fatty acid transport into mitochondria, where it facilitates β-oxidation and energy production^[1]. Subcutaneous administration bypasses intestinal conversion to trimethylamine-N-oxide (TMAO), a metabolite associated with cardiovascular concerns^[4], while providing 100% bioavailability compared to 5–18% for large oral doses^[3]. This educational protocol presents a once-daily subcutaneous approach optimized for insulin-syringe measurements.

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.

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)^[8]. 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.

Use within 2–4 weeks; bacteriostatic water preservative inhibits microbial growth during multi-dose use^[6].

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.

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

Note: Each 200 mg vial reconstituted at 2.0 mL provides two 100 mg doses (or four 50 mg doses).

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): Use 2.0 mL per vial for reconstitution.

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: One for vial stopper + one for injection site each day.

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

Sharps Container: For safe disposal of used syringes and needles.

Protocol Overview

Concise summary of the once-daily subcutaneous regimen.

Goal: Support mitochondrial fatty acid oxidation and energy metabolism while avoiding TMAO production associated with oral dosing^[4].

Schedule: Daily subcutaneous injections for 8–12 weeks (extend to 16 weeks if desired).

Dose Range: 50–100 mg daily with gradual titration; advanced protocols may use up to 200 mg daily.

Reconstitution: 2.0 mL per 200 mg vial (100 mg/mL) for precise 1:1 unit-to-milligram measurement.

Storage: Lyophilized frozen; reconstituted refrigerated; avoid repeated freeze–thaw cycles.
