I'm 35, have been taking 6mg of rapamycin per week for about a year. It's hard to assign the effects directly to it since I've been taking other supplements and also fixing up my diet + exercise. That being said, I am quite sure that it has reduced general aches and pains, reduced visceral fat and I now have less gray hair compared to when I started. It did slightly increase my glucose and lipids, but still within safe ranges AFAICT. I'll continue to take it until I notice real adverse effects.
This comment is quintessential to the issue with HN.
So you are quite young, just had a complete change of lifestyle and your take away is that the beneficial effect comes from the drug you take randomly amongst a cocktail of other things.
