About this compound

L-Carnitine is a naturally occurring amino acid derivative involved in mitochondrial fatty-acid transport, widely used in metabolic research. Supplied in solution at 500mg per mL for laboratory research applications. Independently tested for identity and concentration.

Storage & Handling

Store lyophilized powder at −20°C for long-term stability; short-term 2–8°C is acceptable. Reconstitute with bacteriostatic water; keep refrigerated at 2–8°C after reconstitution and use within typical research timelines.

For laboratory and research use only. Not for human or veterinary use, diagnostic, or therapeutic applications. Statements have not been evaluated by the FDA.

Research Disclaimer: The information below is provided for laboratory and research-use-only educational purposes. It is not medical advice. L-Carnitine is not intended for human or veterinary use, diagnosis, or therapy, and statements have not been evaluated by the FDA.

Compound Overview

What is L-Carnitine?

L-Carnitine is a research peptide supplied by TX Research Peptides for laboratory investigation. It is provided as a lyophilized powder, manufactured to a minimum purity of 99% as confirmed by reverse-phase HPLC and electrospray-ionization mass spectrometry. L-Carnitine is studied in vitro and in animal models in the vitamin & amino acid blends research category.

Research Applications

L-Carnitine in research models

Independent investigators have studied L-Carnitine in cell-culture and rodent models to characterize its biochemical activity. All references to research applications describe published in-vitro or animal studies — L-Carnitine is not approved for human or veterinary use and TX Research Peptides makes no health, therapeutic, or efficacy claims. See the Citations section for primary literature where available.

Mechanism of Action

Receptor & pathway interactions studied

Published research describes L-Carnitine interacting with receptor systems and signaling pathways relevant to its compound class. Specific receptor binding, downstream second-messenger activity, and dose-response profiles are documented in peer-reviewed laboratory studies; researchers should consult primary literature when designing experiments.

Purity & Testing

HPLC + mass-spec verification

Every batch of L-Carnitine is analyzed by reverse-phase HPLC for purity (≥99% by area) and by electrospray-ionization mass spectrometry for molecular-weight identity confirmation. Lot-specific Certificates of Analysis are provided for the strength you order and are linked above as well as on the product page gallery.

Storage & Reconstitution

Handling lyophilized peptides

Store the lyophilized L-Carnitine powder at −20°C for long-term stability; short-term storage at 2–8°C is acceptable. Reconstitute with bacteriostatic water immediately prior to use; once reconstituted, keep refrigerated at 2–8°C and use within typical research timelines. This guidance is concentration / reconstitution information only and is not human dosing advice.
