L-Carnitine is the molecule your mitochondria use to transport long-chain fatty acids into the fat-burning pathway. Without adequate carnitine, fat can't enter the beta-oxidation cycle regardless of your other metabolic conditions. The injectable format delivers consistent, predictable bioavailability for controlled research — unlike oral forms, which are subject to variable gut absorption. True North Peptides supplies L-Carnitine at 500mg/ml in 10ml research-grade vials. For research use only.
What Is L-Carnitine Injectable?
L-Carnitine is the essential gatekeeper of mitochondrial fat burning. Long-chain fatty acids can't cross the inner mitochondrial membrane on their own — they need carnitine as the transport molecule via the CPT (carnitine palmitoyltransferase) system. No carnitine, no beta-oxidation. It's that straightforward. Our injectable format (500mg/ml, 10ml) provides consistent delivery for research models where bioavailability needs to be controlled precisely.
Why Injectable Over Oral?
Oral L-Carnitine bioavailability ranges from 14–18% in most humans — and that number is heavily influenced by gut bacteria, which metabolise a significant portion to TMAO before it reaches systemic circulation. Injectable carnitine bypasses all of that. For research purposes where you need to know exactly how much is actually reaching the tissue, the injectable format is the only way to get consistent data.
What Researchers Are Studying It For
Three main areas: fatty acid oxidation and mitochondrial fuel switching, metabolic efficiency and ATP production, and exercise recovery. Studies have examined carnitine's influence on lactate clearance, oxidative stress markers, and the mitochondrial acetyl-CoA/CoA balance — which affects how efficiently mitochondria can handle fat as a fuel source.
Storage & Handling
