Semax 40mg Pen: Research Overview
What is the Semax pen?
A pre-filled, calibrated research pen holding 40mg of Semax, a synthetic peptide based on ACTH (4-10) with a Pro-Gly-Pro tail, studied in cognition and neuroprotection research. Each click dispenses a fixed 0.01ml micro-volume, about 0.133mg per click on the 40mg pen.
Pen versus vial
The pen is pre-filled with click-based measuring. Semax vials are lyophilised powder that must be reconstituted. Per mg, the 40mg pen (about £1.62 per mg) is cheaper than the 10mg vial (about £2.00 per mg) and close to the 30mg vial (about £1.17 per mg).
