As of October 2026, the cheapest listing is **£6.00** (£0.01/mg) from [Opti-Gen Peptides](https://peptidesupermarket.co.uk/suppliers/opti-gen-peptides), the average is **£25.85**, and the highest is **£51.53** from Biolabs. ## Reading the L-Carnitine price spread The spread between the cheapest and most expensive L-Carnitine listing is about **88%**. A wide spread means it genuinely pays to shop around; a narrow one means the market has settled and most sellers are competitive. The spread bar and order book above update continuously as suppliers change their pricing. ## What moves the L-Carnitine price? - **Dosage size** — larger 600mg vials usually carry a lower per-mg cost. - **Lab testing** — independently tested product typically commands a small premium. - **Shipping** — free-delivery thresholds can flip which supplier is truly cheapest once postage is added. - **Discount codes** — checkout codes can move a listing several places up the ranking. ## Tracking L-Carnitine prices over time The 30-day chart plots the cheapest, average and highest L-Carnitine price each day. Use it to judge whether today's **£6.00** is a genuine low or just the current going rate, and to time your order around the dips. > For in-vitro laboratory research use only.
