Generally, I've failed to note a substantive difference in the results from one product to another. That said, when I began taking a shit load of Beverly mass aminos each day, instead of relying on some well known premium powders, low and behold my recovery and strength improved. Beverly is no bullshit.
Most people get all wrapped up with the bloody labels and base their impressions mostly off of that, which I think is laughable. You can have what is perceived to be the best ingredient profile in the world, but if your results don't improve, who gives a shit?
