Tesamorelin Pen UK: Current Status

The tesamorelin pens and vials supplied by MyPep Biotech are research materials only. They are not medicines, are not licensed products, and are not for human or veterinary use.

What Is the Tesamorelin Pen?

A tesamorelin pen (often called a Tesa pen) is a pre-filled, calibrated research pen holding tesamorelin in a sealed 3ml cartridge. There is no powder to reconstitute and no mixing step, and each click dispenses a fixed 0.01ml micro-volume for repeatable laboratory measurement.

Pen versus vial terminology

A tesamorelin vial contains freeze-dried (lyophilised) powder that must be reconstituted with bacteriostatic water before use. Pens give convenience and consistent click-based measuring; vials give flexible concentration. Read the full tesamorelin pen vs vial guide.
