ZMA ultimate recovery agent

Price is great and all but there is the idea of proven effectiveness.
I made this example a long time ago on this issue somewhere.
BALCO ran a study showing that a rival copy was not effective. The sporting authorities wanted to harm BALCO, so they ran a study using the rival product (coincidence??), said that it didn’t work and claimed “well ZMA is basically the same, so it doesn’t work either”.
ZMA works as offered, whether you like Victor or not.
I’m not willing to screw around looking for an alternative to what I know works.
