Short peptide bioregulator
Cortagen reconstitution calculator
Cortagen is commonly supplied as 10 mg, 20 mg vials. Pick a vial size and a water volume to see the concentration and what each syringe mark holds. Enter a target amount to see the draw. This page does not suggest any amount.
Work backwards: pick how many syringe units you want each draw to be, and the calculator tells you how much water gives that concentration.
Example values shown. Larger draws (10 units or more) are easier to measure accurately than very small ones.
Estimate how long a vial lasts and what a protocol costs, from your own price and schedule.
Example values shown. Replace them with your own.

About Cortagen
Cortagen is a 4-residue peptide from the St. Petersburg Institute of Bioregulation and Gerontology, described by its developers as a bioregulator of the cerebral cortex. Cortagen is described as a synthetic analog of a cortex extract and has been studied by the group for nerve regeneration in rats.
Cortagen calculator questions
How much bacteriostatic water do I add to a 10 mg Cortagen vial?
The calculator does not prescribe a volume; the right choice depends on how large you want each draw to be. As arithmetic: 10 mg in 2 mL gives 5 mg/mL, so each unit on a U-100 syringe holds 50 mcg. Use the “Water to add” tab to work backwards from a draw size.
What concentration does Cortagen have after reconstitution?
Concentration is the vial mass divided by the water volume. For example, 10 mg in 2 mL is 5 mg/mL. Check the certificate of analysis for net peptide content, which is usually lower than the label.
