I remember guys using that with creatine mono.
Most of the people I knew who "liked" it had the fortune of using it in conjunction with a good diet, solid training regimen, and most of them had decent genetics.
Hence, I'm not sure it's appropriate to credit the Vanadyl.
I kind of regard Vanadyl PH as 1993's effervescent Methoxy-Myo-wondersupplement.
It hasn’t withstood the test of time like the basics have.
But, that’s not to say it is totally useless.
At the same time, comments like those B.P. made don't exactly help the cause.
Phillips had a one-hit-wonder with creatine, but eventually overstayed his welcome.
