L-Carnitine 500 mg

Dragon Pharma L-Carnitine

For athletes, bodybuilders, and fitness enthusiasts seeking to optimize fat metabolism, enhance energy utilization, and support androgen receptor sensitivity, L-Carnitine is a foundational compound with significant research backing. While oral L-Carnitine suffers from poor bioavailability (typically 5-15%), the injectable form provides near-complete absorption, delivering the full therapeutic potential of this essential amino acid derivative. This Dragon Pharma L-Carnitine 500mg offering delivers high-purity lyophilized powder in a sterile 2mL vial, providing researchers with a premium injectable formulation for investigating metabolic pathways, fat oxidation, and receptor biology.

L-Carnitine plays a critical role in mitochondrial function by facilitating the transport of long-chain fatty acids into the mitochondrial matrix for beta-oxidation—the process by which fat is converted into usable energy. Research published in the NIH PubMed database demonstrates that L-Carnitine supplementation can increase fatty acid oxidation, improve exercise performance, and reduce muscle soreness following intense training. For athletes in cutting phases, this translates to enhanced fat loss while preserving precious muscle tissue.

Perhaps most relevant to bodybuilders and androgen users is L-Carnitine's profound effect on androgen receptor (AR) density. Research indicates that L-Carnitine upregulates androgen receptor expression, potentially increasing the anabolic sensitivity of muscle tissue to androgens. This has significant implications for both natural athletes and those in enhanced cycles, as improved AR density can amplify the effectiveness of endogenous testosterone or exogenous androgens. Additionally, L-Carnitine has been shown to reduce delayed onset muscle soreness (DOMS), decrease markers of muscle damage, and support recovery between training sessions—critical factors for athletes training with high frequency and intensity.

Quality assurance is paramount in research compounds. Each batch of our L-Carnitine 500 mg inventory undergoes rigorous third-party HPLC-MS testing to verify purity and dosage. The most recent batch (September 2025) tested at an exceptional 525.08 mg—exceeding the label claim—with batch number #LCARHD8. This level of transparency and quality control ensures that researchers can trust the integrity of the compounds they are investigating.

For bodybuilders and strength athletes navigating the demands of contest prep or massing phases, injectable L-Carnitine offers a versatile tool. Its effects on fat oxidation support cutting goals, while its impact on androgen receptor density and recovery mechanisms benefits athletes in all phases of training. Whether investigating strategies for enhanced fat loss, improved metabolic efficiency, or optimized receptor sensitivity, Dragon Pharma's L-Carnitine delivers the purity, potency, and reliability required for serious research.

Product Specifications

Usage Guidelines

L-Carnitine is supplied as a sterile lyophilized powder and must be reconstituted with bacteriostatic water or sterile saline prior to research use. For optimal stability, gently swirl the vial after adding the diluent—do not shake vigorously. Standard research protocols involve reconstituting the 500mg peptide with 2-5mL of bacteriostatic water, yielding a concentration of 100-250mg/mL. Typical research dosing ranges from 200-500mg per administration, often administered pre-workout to enhance fat oxidation during training. Due to its excellent solubility, L-Carnitine can be administered intramuscularly or subcutaneously. It is recommended to store the reconstituted solution in a refrigerator (2-8°C) and use within 30 days.

For researchers investigating comprehensive metabolic and anabolic protocols, combining L-Carnitine with complementary compounds can yield synergistic insights. Consider exploring the following Dragon Pharma products to enhance your research:

• GW501516: A PPARδ agonist studied for enhanced fatty acid oxidation and endurance in combination with L-Carnitine.
• Aicar: An AMPK activator researched for metabolic enhancement and mitochondrial biogenesis.
• MOTS-c: A mitochondrial-derived peptide studied for metabolic regulation and exercise adaptation.
