I have been taking metformin for anti-aging purposes for about 6 months now. I decided to take it mainly because the risks are small, and I wanted to counter the natural bias on these sorts of things, which always leans towards "doing nothing". By taking metformin, it means I have a personal stake in the developoment of anti-aging medicines and have a reason to evaluate any newer options that appear (since there may be a reason to switch metformin to another treatment) I feel like taking metformin makes me less biased when it comes to evaluating treatments in the field, even if I think the efficacy of metformin is still an open question. In terms of side effects, I have noted mild gastric upset (I actually wonder if this is part of its mechanism of action, making you less hungry in this way) but little impact on exercise (I take it even on days that I exercise, and I have a fairly heavy exercise routine)
