A short peptide from Russian research, studied in animals for nerve repair.
The basics
- What is it?
- Cortagen is one of the Khavinson short peptides. Nearly all published work is animal or cell research from a small number of Russian groups.
Official status: Not nominated for 503A compounding · Checked 2026-08-04
Can a doctor prescribe this?
- Small pharmacy (503A)
- Never put forward to FDA
- Large outsourcing facility (503B)
- Never put forward to FDA
Not FDA approved and not on the U.S. compounding list. A doctor cannot prescribe it.
503A is a pharmacy making a single prescription for one patient. 503B is a facility making batches. They are governed by separate lists. Where a category is shown, it is a position on the FDA's list of substances that have been put forward and are still being worked through — not the final list, which is set by rulemaking. Category 1 means the FDA does not plan to act against a pharmacy that makes it while the review runs.
