I've been using Metformin for over a year due to developing Metabolic syndrome caused by my HT regime which I stopped nearly 2 years ago. I have increased the dose from 500mg to 2000mg in the last 3 months to gain even tighter control of my BG levels even though they are not that bad. I firmly believe that it offers an overall positive health benefit.
3 months ago my PSA was 0.13, last week 0.12 so I'm very happy achieving this on just Metformin and Avodart (even more so given my starting PSA ). Interestingly, my cholesterol tests were vastly improved as well even though I stopped taking them 6 months ago .
Cheap as chips (Zufus alert! ) with minimum SE makes me very happy!
