ARA-290 (Cibinitide)

Research Use Only
peptideSubcutaneous injection

Derived from the blood-building hormone EPO, but modified so it activates your body's built-in repair system without increasing red blood cell production. It protects nerves, shields tissues from damage, and fights inflammation. Studied for nerve damage (small fiber neuropathy) and the inflammatory condition sarcoidosis.

Dosing

2-4 mg subq daily for 28 days. Can be repeated after a break.
