L-Carnitine

L-Carnitine 5000mg/mL is supplied as lyophilized powder under nitrogen. Typical reconstitution is in sterile or bacteriostatic water; the exact concentration depends on your protocol. Our free reconstitution calculator computes mL per dose and insulin-syringe units from any combination of vial size, water volume, and target dose.

Batch LC50-2608 of L-Carnitine 5000mg/mL is verified at 99.0% HPLC main-peak purity, with confirmation of molecular weight by LC-MS and endotoxin screening by LAL assay. One vial of every batch is also shipped to an independent US-based third-party lab for blinded re-verification. The full COA — including the chromatogram, mass spec trace, and third-party report — is bundled with your order as a downloadable PDF.

All orders ship cold-chain via DHL Express from our Qingdao facility. Cold-pack is validated to hold under 8°C for 96 hours. Customs duties are prepaid by us — no surprise charges on delivery. Estimated transit time is 7-10 business days door to door. Tracking number is emailed when the shipment is scanned by DHL.

ACH bank transfer (2% off, recommended), USDC / BTC / ETH crypto (5% off), Zelle, CashApp, Venmo, or wire transfer for institutional orders. We do not accept credit cards because card processors prohibit research-peptide merchants in their terms of service. Full payment-method details are on the shipping & payment page.

Lipolytic compounds vary in their effects on the GH/IGF-1 axis. The molecule-specific data appears in each compound's published characterization. AOD-9604 is the best-characterized example of a lipolytic GH fragment with minimal IGF-1 effects.

Unlike the GLP-1 family (which acts through incretin receptors), L-Carnitine acts through a non-incretin mechanism, making it a complementary research tool when probing mechanisms separate from incretin biology.
