Description:
L-Carnitine is a naturally occurring quaternary ammonium compound synthesized from lysine and methionine. It plays a critical role in fatty acid metabolism, acting as a shuttle that transports long-chain fatty acids across the mitochondrial membrane for β-oxidation. The injectable form bypasses gastrointestinal absorption, offering superior bioavailability and rapid systemic uptake, making it ideal for studies involving energy metabolism, endurance, and fat mobilization.

⚙️ Mechanism of Action:
L-Carnitine facilitates the transport of fatty acids into the mitochondrial matrix by forming acyl-carnitine esters, enabling their conversion into ATP via oxidative phosphorylation. It also supports mitochondrial buffering, reduces acyl-CoA accumulation, and may enhance insulin sensitivity in skeletal muscle. In research models, it has been shown to increase VO₂ max, reduce fatigue, and improve recovery post-exercise.

📈 Research Applications:
Injectable L-Carnitine is under investigation in preclinical and in vitro models for:
• Fat oxidation and body composition modulation
• Exercise performance and endurance enhancement
• Mitochondrial biogenesis and metabolic flexibility
• Neuroprotection and cognitive function
• Cardiovascular and hepatic energy metabolism
It is also frequently studied in stacked protocols with agents like AOD-9604, 5-Amino-1MQ, or Retatrutide to explore synergistic fat-loss and metabolic effects.
