Supplied for laboratory research use only. Not for human or veterinary use, and not intended to diagnose, treat, cure or prevent any disease.
Overview
L-carnitine is a small quaternary ammonium compound synthesised in the body from lysine and methionine, with a hydroxyl and a carboxylate group that let it form reversible esters with fatty acyl groups. That single chemical trick is the basis of the carnitine shuttle: long-chain fatty acids cannot cross the inner mitochondrial membrane as CoA thioesters, so carnitine palmitoyltransferase 1 transfers the acyl group to carnitine, a translocase carries the acylcarnitine across, and CPT2 hands it back to coenzyme A for beta-oxidation. Only the L-enantiomer is biologically active; the D-form is an inhibitor and is not used in research preparations.
This listing is a ready-mixed aqueous solution of levocarnitine at 200 mg/mL, supplied in 10 mL and 30 mL sealed vials. The solution format removes weighing and dissolution steps for laboratories running metabolic, mitochondrial or acylcarnitine-profiling work, and it is the same concentration convention used in the compounded lipotropic preparations that combine carnitine with MIC nutrients and B12.

Questions about L-Carnitine Injection
What concentration and volumes are supplied?
Both sizes are 200 mg/mL levocarnitine in aqueous solution: a 10 mL vial containing 2 g total and a 30 mL vial containing 6 g total. The concentration is verified per lot and reported on the certificate of analysis supplied with the batch.
Why solution rather than powder?
Solid L-carnitine is strongly hygroscopic and picks up atmospheric moisture during weighing, which introduces a concentration error into every downstream dilution. A pre-mixed, lot-verified solution removes that variable and saves a preparation step in metabolic assay work.
Is a certificate of analysis available?
Yes. Each lot ships with a matching COA reporting identity and measured concentration. Quote the lot number when requesting a copy, and file it with your records so material grade can be reported alongside experimental results.
How does L-carnitine relate to Lipo-C?
Lipo-C is a compounded lipotropic solution combining methionine, inositol and choline with vitamin B12 and L-carnitine. This listing is the single compound on its own, which is the format laboratories prefer when carnitine itself is the variable being studied rather than a mixture.
Can this be administered to people or animals?
No. It is supplied strictly for laboratory research use by qualified personnel. It is not a drug, supplement or veterinary product as sold, and it must not be administered to humans or animals outside an approved research protocol.
