The first-ever reverse-aging drug was just injected into a human

14. I don't think so

The entire body doesn't reverse age but just the tissues, muscles, and organs that are targeted. What it could possible do is alleviate the usual problems a 75-year old person would have and leave them with the physical properties of a 45-year old. This would mean the 75-year old would be able to work and possibly live longer. It's the longer life spans the treatments provide that would create new problems for society on how we treat those with longer lifespans and the effect those with longer lifespans would have on younger generations. For example, if the treatment allows someone in their 60s to work another 30 years then the opportunity for the younger generations to move into the jobs the older workers have decreases limiting the younger generation's ability for upward mobility and financial success.
