PT-141 Pen

The pen format exists for one reason: repeatability. Instead of drawing from an open vial with a syringe, the 10 mg cartridge is loaded into a click-dosing device, so a protocol that repeats the same increment many times does not accumulate measurement drift between draws. Priming clears the air gap before the first increment is counted, and the dial handles the arithmetic that would otherwise be done on a syringe barrel. Standard 31G pen needles fit and are sold separately. The device is designed for cold transport and arrives insulated. This is a laboratory measurement instrument holding a research compound, not a medical product, and no marketing authorisation exists for it in the European Union. For research purposes only, not for human consumption.
