L-Carnitine 500 mg

Dragon Pharma L-Carnitine 500 mg – Injectable Amino Acid for Fat Metabolism Research

Dragon Pharma L-Carnitine (Levocarnitine) is an amino acid derivative that plays an essential role in cellular energy metabolism. Its primary function is the transport of long-chain fatty acids into the mitochondrial matrix for beta-oxidation — the process by which fat is converted into usable energy. Unlike oral carnitine with poor bioavailability, the injectable form provides significantly enhanced absorption and tissue saturation for research purposes.

If you're looking for legit L-Carnitine for research purposes, this compound has gained attention for its potential to support fat oxidation, increase androgen receptor density, reduce muscle soreness, and improve metabolic efficiency. For researchers studying fat metabolism, endurance performance, or recovery optimization, injectable L-Carnitine offers a well-characterized and bioavailable research tool.

Why Athletes & Bodybuilders Are Researching L-Carnitine

Fat loss and metabolic efficiency are critical for athletes and bodybuilders during cutting phases. Injectable L-Carnitine research suggests it may enhance fatty acid oxidation, increase androgen receptor expression in muscle tissue, reduce markers of muscle damage, and support recovery. Unlike oral carnitine which has poor absorption (10-15% bioavailability), the injectable route offers complete bioavailability for more consistent research outcomes.

What Makes Dragon Pharma L-Carnitine Different?

• ✔ Injectable formulation — 100% bioavailability vs ~10-15% oral
• ✔ Shuttles fatty acids into mitochondria for beta-oxidation
• ✔ Researched for increased androgen receptor density in muscle
• ✔ Also studied for recovery, DOMS reduction, and metabolic health

Note for researchers: Injectable L-Carnitine offers significantly different pharmacokinetics than oral forms. For best results in your research, follow established protocols and always source L-Carnitine from verified suppliers like Dragon Pharma.

Product Specifications

Dosage, Reconstitution & Research Guidelines

Reconstitution Instructions (500 mg Vial)

L-Carnitine comes as a lyophilized powder in a 2 mL sterile vial. You'll need sterile water or bacteriostatic water to reconstitute it properly.

• ✔ Add 2 mL of bacteriostatic water to the vial
• ✔ Final concentration: 250 mg per mL
• ✔ Gently swirl — do not shake
• ✔ Refrigerate after reconstitution and use within 14 days

Typical Research Dosing

Based on available research literature, typical L-Carnitine dosing in research models falls in this range:

• ✔ 250 – 1000 mg per injection (IM administration in larger animal models)
• ✔ Typically administered 2-3 times per week depending on research protocol
• ✔ One 500 mg vial provides 1-2 research doses depending on dose
• ✔ Often studied in conjunction with metabolic or performance research protocols

Injection Volume Guide

Using a standard 3 mL syringe with L-Carnitine reconstituted to 250 mg/mL:

• ✔ 1.0 mL = 250 mg
• ✔ 2.0 mL = 500 mg
• ✔ 3.0 mL = 750 mg
• ✔ 4.0 mL = 1000 mg (requires additional diluent)
• ✔ For IM injection — deep into muscle tissue for systemic research

How Athletes & Bodybuilders Are Researching L-Carnitine

Injectable L-Carnitine is researched for its effects on fat oxidation, androgen receptor density, muscle recovery, and metabolic health — all relevant to body composition and performance research.

Popular research stacks include:

• ✔ L-Carnitine + AICAR — for complementary metabolic and AMPK research. View AICAR →
• ✔ L-Carnitine + GW501516 (Cardarine) — for enhanced fat oxidation and endurance research. View GW501516 →
• ✔ L-Carnitine + AOD 9604 — for combined fat metabolism research. View AOD 9604 →

Research Protocol Example (4-6 Weeks)

• ✔ Weeks 1–6: L-Carnitine 250-500 mg IM 2-3x weekly
• ✔ Weeks 1–6: AICAR 50-100 mcg daily (optional stack for metabolic research)
• ✔ Post-cycle observation: 1-2 weeks off before next research phase

Important Considerations

• 🔬 Injectable L-Carnitine provides 100% bioavailability — significantly different from oral research
• 💧 Often researched alongside insulin or carbohydrate for cellular uptake studies
• ⚠️ Some research notes TMAO production — monitor in long-term protocols
• 📦 IM injection is standard for systemic research applications
• 📦 Always source L-Carnitine from verified suppliers like Dragon Pharma

Storage Guidelines

Before Reconstitution (Lyophilized Powder)

• ✔ Store at 2–8°C (36–46°F) — standard refrigerator temperature
• ✔ Do not freeze the lyophilized powder
• ✔ Keep in original packaging, away from light
• ✔ Stable for up to 12 months when refrigerated properly
• ✔ Avoid repeated temperature changes (don't take in and out of fridge unnecessarily)

• ✔ Use within 14 days of reconstitution
• ✔ Do not freeze after reconstitution
• ✔ Keep vial upright and sealed between uses
• ✔ Avoid direct light exposure

What to Avoid

• ❌ Freezing (before or after reconstitution)
• ❌ Leaving at room temperature for extended periods (>24 hours)
• ❌ Shaking the vial — swirl gently instead
• ❌ Using cloudy or particulated solution after reconstitution
• ❌ Storing in bathroom or near heat sources

Inspection Before Use

• ✔ After reconstitution, solution should be clear and particle-free
• ✔ Crimp seal must be intact — do not use if seal is broken or missing
• ✔ Check batch number and QR code for authenticity before use
