big blast, dx7, and straight spp are all bad ass products from pf. i add the glutamine peptides, l glutamine, microlactin, and peak atp to my big blast i find all of them to be great as soon as i finish my last rep of my last set. i use the spp 1 tsp at a time mixed with a little apple sauce several times per day just for a steady flow of quality protein. of course gear is an easier alternative to this.
