L-Carnitine is the naturally occurring amino acid derivative essential for shuttling long-chain fatty acids into mitochondria for beta-oxidation and ATP production, as described in scientific literature ([ods.od.nih.gov](https://ods.od.nih.gov/factsheets/Carnitine-HealthProfessional/)). The L-form is the only biologically active isomer — D-carnitine is inactive and potentially inhibitory. First identified in 1905 and synthesized in the 1950s, it is widely studied in metabolic, mitochondrial, and cardiovascular research contexts. This research-grade crystalline powder is produced under strict quality controls and includes full analytical documentation, making it suitable for in vitro and laboratory studies of fatty acid metabolism and mitochondrial function.

Frequently asked questions
How should I reconstitute this peptide?
Use bacteriostatic water for short-term lab storage. Direct the diluent down the side of the vial, swirl gently — do not shake.
What is the shelf life?
Lyophilized peptide stored at −20°C is stable for 24+ months. Reconstituted peptide should be refrigerated and used within 2–4 weeks.
Do you ship internationally?
We currently ship within the United States only. International researchers should contact our bulk team for institutional quotes.
