Overview
Biochemical Characteristics
L-Carnitine exists as a zwitterion with a quaternary ammonium group and a carboxylate group. The molecule's amphipathic nature enables its function as a carrier for acyl groups across mitochondrial membranes, essential for fatty acid oxidation in experimental models.

Common questions
- What purity is L-Carnitine, and how is it tested?
- L-Carnitine is supplied at 99%+ purity. Each production lot is tested by an independent third-party laboratory, with HPLC for purity and mass spectrometry for identity. Published certificates can be looked up by the lot number printed on your vial in our COA library.
- Does L-Carnitine come with a Certificate of Analysis?
- Certificates are published online rather than printed in the box. You can view and download the certificate on this page before you buy, and match the lot number on your vial to its certificate in the COA library. Our guide on how to read a peptide COA explains each section.
- How fast does L-Carnitine ship?
- Orders placed before 2 PM EST ship the same day from the United States, with tracking and discreet packaging.
- How should L-Carnitine be stored?
- Store at room temperature, protect from light. Our storage and handling guide covers temperature, light and moisture in more detail.
- What if independent testing doesn't confirm the stated purity?
- Our Purity Guarantee covers it: if independent testing does not confirm the stated purity, you get a full refund and a free replacement.
- Is L-Carnitine for human use?
- No. L-Carnitine is sold strictly for laboratory research use only. It is not for human or veterinary use, and we do not provide dosing or administration guidance.
