For In Vitro Use Only — Not for Human Use
Every batch is independently HPLC & mass-spec tested. Certificate of Analysis is batch-numbered and matched to the vial you receive.
Replacement pre-filled cartridge for customers who ALREADY OWN a Quick Pen. Custom-prepared under sterile conditions and screws straight into your existing pen. A cartridge on its own is useless without a pen — if you do not already have a Quick Pen, order the full Quick Pen (£34.99) instead.
A ready-to-use replacement cartridge, custom-prepared under strict sterile conditions with the peptide of your choice. Designed as a REFILL ONLY for customers who already own a Quick Pen from a previous order. It screws straight into your existing pen — no reconstituting, no waste, no bacteriostatic water required.
Please read carefully before ordering: this cartridge is NOT a standalone product. Without a Quick Pen device it cannot be used to inject and it will NOT work on its own. It is non-refundable if ordered by mistake. If this is your first order, or you do not currently own a Quick Pen, order the full Quick Pen (£34.99) instead — that comes complete with the pen device, cartridge, screw-on needles and dosing guide.
