I just started Metformin and it's hard to say I'm doing HGH + tren and I'm at the end of the cycle and tired of dieting down and slacking a bit on cheat meals.
So my bf is jumping up and down ahaha
To really know the difference one should do one month eating always the same calories intake with metformin and then compare it to a month without Metformin.
I'll probably do it, just not this time.
Again all these are just speculation, even if it has no other benefit except lowering my BG and increasing insulin sensitivity, I would be more then happy, those two things are already very very good.
Especially on a bulk were insulin resistance will increase with all those carbs + the HGH...
