How pricing works

Vial price, plus a laboratory preparation fee

Each preloaded pen is priced automatically from the parent compound's vial price plus £25 for laboratory preparation and handling. No second price list, no manual adjustment.

• Example BPC-157 vial £16 becomes a preloaded pen at £41.
• Example GHK-Cu vial £30 becomes a preloaded pen at £55.
• Example Semax vial £20 becomes a preloaded pen at £45.

Retatrutide and Tirzepatide are supplied on their own tiered pen pricing on the respective product listings, and are excluded from this configurator.

Guidance on dilution and strength per unit of volume is available through our interactive dilution strength calculator for pens.
