As of October 2026, the cheapest listing is **£12.24** (£1.22/mg) from [XL Peptides](https://peptidesupermarket.co.uk/suppliers/xl-peptides), the average is **£29.69**, and the highest is **£199.99** from Premio Peptides. ## Reading the Semax price spread The spread between the cheapest and most expensive Semax listing is about **94%**. 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 Semax price? - **Dosage size** — larger 10mg 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 Semax prices over time The 30-day chart plots the cheapest, average and highest Semax price each day. Use it to judge whether today's **£12.24** 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.
