FAQ
L-Carnitine — frequently asked by B2B buyers.
What form and vial sizes does Pepti supply L-Carnitine in?
Pepti supplies research-grade L-Carnitine in solution vials — 600 mg / 10 mL and 216 mg / 10 mL formats — with private-label and OEM options. Bulk powder and custom fill volumes are available on request.
What documentation ships with each lot?
Every lot ships with a certificate of analysis (COA) covering HPLC purity, mass-spectrometry (MS) identity confirmation, and appearance/water-content data. Safety data sheets and analytical method details are available on RFQ.
Is L-Carnitine the same as levocarnitine or L-Carnitine tartrate?
L-Carnitine (CAS 541-15-1) is the free-base levocarnitine — the active L-(-) enantiomer. Salt forms such as L-Carnitine tartrate (CAS 36687-82-8) and L-Carnitine hydrochloride (CAS 6645-46-1) carry different CAS numbers and molecular weights, so specify the exact form required on your RFQ.
What is the minimum order quantity?
Standard MOQ is 50 vials. Larger volumes and bulk raw-material (kg-scale) pricing are handled through RFQ, with tiered quotes for private-label programs.
How is L-Carnitine stored and shipped for B2B orders?
L-Carnitine is hygroscopic; sealed powder is stored at -20 °C protected from moisture and light, and aqueous or reconstituted solution at 2–8 °C. Cold-chain handling and international shipping documentation are arranged per order.
