ok, so i've only noticed two companies promoting HSP products (MuscleTech and MRI)... is this a legit breakthrough in musclebuilding supp technology?
i was reading up on MRI's claims on this technology, and these HSPs are functional proteins that are generated inside your body, meaning that they aren't dietary proteins (whey protein, for example)...?
i don't fully understand it... can anyone shed some light on HSPs?
