in all honesty, both of these are poor products ESPECIALLY the syntha 6... bsn is one of the lower quality mainstream companies out there... muscle pharm used to be a lot better with overall product quality as well but have taken steps backwards the last few years with quality of products and reformulations... its quite disappointing to see... there are far better options than what you are using... whey to build muscle is a micro filtered protein with a full amino profile, top quality whey and on top of that, the best tasting...
