Buy L-Carnitine UK — Liquid Solutions Need Identity Too
L-Carnitine is supplied as a ready-to-use liquid solution, and the checks shift slightly: the CAS number, the stated concentration, and a batch record that confirms identity — because a liquid formulation is harder to verify than a powder.

1. Check the concentration and CAS
L-Carnitine is CAS 541-15-1. Index Peptides supplies a ready-to-use 10ml liquid research solution at 500mg/ml — the listing should state the concentration and the CAS so the format is unambiguous.
2. Identity verification per batch
For a liquid solution, identity verification is the documentation that matters most. The batch record should confirm the identity of the material, carry a lot number, and be checkable independently on a public batch-verification page.
3. UK dispatch and the research-use boundary
UK-based dispatch avoids customs uncertainty on research materials, and a credible supplier states plainly that products are for laboratory research only — never for human or animal use.
How to order from Index Peptides
