my experience is simple. i had some rigs from a diabetic. i bought some injectable B12 on line. i gave myself one mg doses every day for a little over a week. now i can no longer feel their effects immediately. but the overall effect has been very positive. much more responsive metabolism. much stronger musculature. more of a feeling of stamina than before. much smoother muscle control. i feel warm all the time at any temp. its a complete 180 from feeling cold at any temp only ten years ago.
google B12 and chronic fatigue syndrome. i hope to be giving some mineral lessons on my forum soon. guess what mineral i was missing?
