You can`t compare colostrum to a embryo extract, the colostrum contains just a few growth factor it not all 22 FGF, is not a endogenous sours, this is juts a small part. Here why cant compare it : The embryo extract naturally contains all the natural catalog stem cell biosimilar microRNAs, endogenous pep-tides, growth factors and pluripotent Yamanaka factors. This catalog includes; Activin, Cationic peptides,IGF-1, IGF-2, FGF (fibroblast growth factors), NGF (nerve growth factors), EGF (epidermal growth factors), CTGF (connective tissue growth factors), Immunoglobulins, Immune-Regulating Anti-Inflammatory Cytokines, and TGF (Transforming Growth Factor Beta) Follistatin, Thymosin B4 and Erythropoietin (EPO) – stimulates red blood cell production for oxygenation needed to heal wounded tissues.
