Bioactive protein peptides
Isatori's Bio-Gro is a muscle-supporting protein formulation
derived from concentrated colostrum. Specifically, Bio-Gro is said by its
manufacturers to provide proline-rich peptides, the growth factors IGF-1,
TGF Beta-2, EGF, PDGF, plus unspecified amounts of immunoglobulins IgG,
IgA, and lactoferrin, all intended to spur increased protein synthesis and
consequent muscle support.
