Metformin Impairs Exercise Training-Related Improvements In Older Adults

I would imagine any impairment would be mitigated by those using exogenous testosterone & gh and the associated benefits of Metformin would be enjoyed?

I mean, no supplement stack is going to be as efficient if your gh and testosterone is close to zero, and stacks discussed on forums like this including rapamycin et.al will also not be as efficient in such a deficit so, eat your gh and testosterone vitamins, boys and girls.
