Bovine Colostrum

Bovine colostrum is the first milk produced by cows giving birth. This special milk has been known to be specifically designed by nature to improve immune function and increase levels of IGF-1.

If you have the dough, replace 5-10g of protein in your pre- and post-workout shakes with 5-10g of bovine colostrum.

Otherwise, buy in capsule form and take 1 - 2 at bedtime or as directed.
