What is KLOW Pen?

KLOW combines the copper tripeptide GHK-Cu with BPC-157, TB-500 and KPV in a single ready-to-use pen, extending the GLOW blend with KPV's anti-inflammatory research profile.

All four components are verified together on the batch certificate of analysis; the pen format exists purely to remove the weighing and mixing step required for the vial.

Storage & handling

Storage

Keep refrigerated at 2–8 °C, in line with other prefilled research pens. Use within 10 weeks of first use. Avoid leaving the pen out of the fridge for extended periods, and keep it away from direct heat and light.
