Metformin drug combo suppresses growth of late-stage prostate cancer tumors -so far in a lab setting

Do ther Purdue researchers ever define what quantity is low dose of Metformin?

I think Dr Myers suggests 1000 Mg twice a day.

I had been taking 500 Mg *2 and am phasing into 1000 Mg *2 as it can cause urgency.
