The mhra which is the uk version of the USA fda has approved it for life long use. The op’s question I think is poorly phrased, you don’t need to stay on, you don’t need to come off, it’s a personal choice.
on the anti ageing, they have found this in trials and now are doing new trials specifically on it.
on the report I read, basically it said every time we get ill or hurt ourselves, our cells do not fully recover. They carry a marker of that, which is inflammation in the main, this is ageing, it is the cumulative effect of every time we get a virus, or some damage ie too much fat, booze, whatever,
when you remove that inflammation, the cells are able to regenerate, the inflammation reduces our cells ability to fully regenerate, so when the cells fully regenerate, ageing either slows, halts, or in some people reverse. It’s different for everyone.
I’m talking internally, our organs. Not your skin ie wrinkles, that’s about collagen etc and a different thing,
so yes, it is now thought it has an anti ageing effect, and entering trials for this specifically, it appears the “fountain of youth” isn’t about our appearance, but our organs internally, and they may have found it, it would require tweaking if we get to the stage where it is taken for this purpose.
we need to remember this is just a synthetic peptide, one we produce naturally, but that we produce less of as we age, and I guess some folks never produce enough of, but it’s a very important one. And by taking more of it, our bodies start to work optimally again.
