As of October 2026, the cheapest listing is **£30.00** (£1.50/mg) from [Midshire Labs](https://peptidesupermarket.co.uk/suppliers/midshire-labs), the average is **£43.48**, and the highest is **£48.99** from Biolabs. ## Reading the Cortagen price spread The spread between the cheapest and most expensive Cortagen listing is about **39%**. 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 Cortagen price? - **Dosage size** — larger 20mg 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 Cortagen prices over time The 30-day chart plots the cheapest, average and highest Cortagen price each day. Use it to judge whether today's **£30.00** 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.
