L-Carnitine

L-Carnitine 20ml Vial from Xcel Peptides

Xcel Peptides supplies L-Carnitine as a research-grade amino acid derivative in a 20ml sterile vial for laboratory use. We test every batch independently before release, and we publish the certificate of analysis on this page, matched to the batch number on your vial.

What Is L-Carnitine

L-Carnitine is a naturally occurring compound central to the carnitine shuttle, the mechanism that transports long-chain fatty acids into the mitochondria for energy substrate utilization. Researchers use it as a catalog input for controlled studies on fatty acid transport, since it plays a defined and well-characterized role in that pathway.

Specifications

The vial holds a sterile solution, 20ml in volume, at research grade. We verify it through third-party HPLC and identity analysis, and we document every batch with a matched COA. Refrigerate the vial and protect it from light. We ship every order cold-chain with tracking.

Research Applications

Scientists study this compound across fatty acid metabolism pathways, mitochondrial function, and cellular energy regulation in controlled laboratory environments. Its role in the carnitine shuttle makes it a common reference point for research into how cells generate energy from lipid substrates, and for comparative studies against other metabolic cofactors.

These describe research applications, not therapeutic claims. The FDA has not evaluated this product, and researchers should not use it to diagnose, treat, cure, or prevent any condition.

Why Buy L-Carnitine From Xcel Peptides

Concentration and purity vary widely across suppliers in this category, and a mislabeled vial throws off every downstream calculation in a study. Xcel Peptides tests each batch independently and publishes the resulting data, so you can confirm actual concentration before you rely on it.

We ship every order with cold-chain packaging as standard. Solution-format compounds react to heat more than dry material does, so temperature control during transit protects the product from the moment it leaves our facility.

Storage and Handling

Refrigerate the vial and keep it sealed and shielded from light. Avoid repeated warming and cooling, since temperature cycling degrades solution stability faster than steady cold storage does. Once opened, follow standard sterile handling practice for the remainder of its use.

Verifying Your COA

Check three things on the COA before you use this product. First, confirm the batch number matches your vial. Second, confirm the test date is recent. Third, confirm the concentration value matches the specification listed above. If you need archived data for a previous lot, contact our team and we’ll pull it for you.
