The human body is too complex to prolong life only through drug treatment. Reverse aging requires technologies that mimic a particularly healthy lifestyle (mental & physical), some of which do not exist) based on energetic infusion.
3D organ printing technologies are likely to evolve in the coming decades. The drugs will be replaced by technologies that mimic a healthy diet & lifestyle. It is important to emphasize that human heredity was not built to reach the age of 150 with a good quality of life. To get the age of 150, it is necessary to lower the metabolic rate, but this requires drastic genetic changes that may completely change the human race. The primary challenge is a mathematical-statistical cracking of the subconscious and its effects on the human body. At the moment, we are not at all close to being able to bring people to a life expectancy of 150 years. The increase in life expectancy has dropped dramatically and is stabilizing.
