AST Sports Science Raptor HP Reviews Brian E. November 25, 2014 Protein Supplement Reviews, Reviews AST Sports Science is launching a brand new beef protein powder called Raptor HP, which features hydrolyzed beef protein isolate peptides in its main protein blend. With the sudden popularity of beef protein powder supplements I’m inclined to take the cynical position that companies like AST are just trying to take advantage of a trend. However, Raptor HP hasn’t officially launched yet, so it’s impossible to say for certain what to expect from it. I’ll give you a complete update and review as soon as it becomes available, so be sure to check back soon.
