I see alot of guys around here running metformin year round, myself started using it for a couple of months during a bulk cycle at 1000mg/day.
works great BG is in the the 70' down from 90' even though I eat a ton of carbs.
The first thing I noticed after a couple of weeks is a loss of strength and mind you I was on 600test c and 300 deca so that should not have been the case....
The second thing was the weight did not go up even as I was eating like a bastard (deca makes me eat the house)...
very strange indeed and the only new variable was the metformin so I started to research and stumbled across an UK GOV warning for B12 deficiency induced by long term metformin treatment, and also anecdotal reports on strenght forums of people feeling like shit in the gym before suplementing with b12...
I plan to do blood works to see what my levels are but in the mean time have any of you guys experienced this fatigue running metformin?
