The package arrived very quickly and it was the real deal. There is a NIH paper that they collected many cerberoprotein products that are sold as Cerebrolysin and only the original boosted the brain BDNF. I had previously bought Cererbrolycin from Kimera that is usually a good source of research products, but the color was dark and it caused post injection pain, i.e., it was not the real deal. This one is, although it is made in Austria and not Russia.
