>>43985Take sunscreen to prevent premature aging, it won't stop aging as such but accelerated aging from sun exposure, but if you didn't wear it in youth some damage has already been done that will catch up to you in old age.
As for things other than sunscreen tretinoin is the gold standard for anti-aging pretty much any other cosmetic product other than sunscreen is cope.
Finasteride to keep hair obviously.
TRT for quality of life especially once past middle age not so much for anti-aging, HGH isn't really necessary and increases cancer risk.
Eat as less as possible, but obviously longevity isn't much useful if your quality of life is shit so you want to have a balance in this regard such as to maintain muscle mass in old age and avoid nutrient deficiencies.
And of course avoid stress and have good health/sleep in general.
