How to order a Quick Pen:
Looking for a specific pre-filled pen?

⚠️ Please read before ordering
ONLY order the Pre-Filled Cartridge if you ALREADY OWN a Quick Pen from a previous order.
A cartridge on its own is USELESS without a pen. You will NOT be able to inject with it. It will NOT work as a standalone product. It is NON-REFUNDABLE if ordered by mistake.
If this is your first order or you do not currently own a Quick Pen, please order the full Quick Pen (£34.99) instead — that comes complete with the pen device, cartridge, screw-on needles and dosing guide.
A ready-to-use refill cartridge, custom-prepared under sterile conditions with the peptide of your choice. Screws straight into your existing Quick Pen — no reconstituting, no waste. Cold-shipped for next-day UK delivery.
