Really...IMHO MRI is a quality company. Ed Byrd (founder) is the one who first linked nitric oxide to good pumps in workouts. Besides, unlike companies like BSN & MuscleTech, MRI doesn't spend a ton of money on high profile BBs to endorse it's products; hopefully that means that the cost of the product goes back into R&D rather than someone's pocket.
Also, I've had a lot better results with MRIs NO products than BSNs...of course, that's just me.
I will concede that MRIs products are a bit pricey but my part time job at GNC knocks 30% off the price, which makes them affordable (for me).
Just my two cents worth.
