Question about Progenitor Cells

[Josua]

According to some posts that I found after searching the Net, the Progenitor Cell supposedly has the following Age Conversion Formula for the effects of its life extension properties, with some direct quotes from the post:

((Age - 20) / 2 ) + 20
Or in other words, you develop normally to adulthood (age 20) and then past that, you only age 1/2 year biologically every calendar year.​

What I want to know is this: Are the effects of the Progenitor Cells permanent (permanent per procedure), or is it something that constantly needs to be maintained (lest its effetcs would be lost)? If it's the former, is it stackable to continuously slow the aging process further? Or is it something that simply halves the aging process flat-out as per lore?
If it's stackable does the formula becomes more like:

((Age - 20) / n ) + 20
Where the n is the rate of the halving, so to speak.​

With the n in the first procedure being n = 2, AKA the default rate. And after undergoing another procedure, the n there being n = 4.
Or in other words, it's like the n becomes n*2 (or it essentially doubles) every time a procedure is done.

Does it become like that? Or no? I'm genuinely curious.

Most likely it's a constant thing. Keep taking treatments keep staying young. Some of the named characters like salvation lived through the first thargoid war putting him at over 200 and still in good form until he passed away due to external circumstances.

Some folks have used cloning as a way to expand the lifespan as well.

From what ive been told there is reason to believe the Progenitor cells are linked to guardian technologies
It does appear from the way they are spoken about in lore it is a treatment that one must regular adminaster , although how often and to what degree
is largely left in the dark, like many things in the game world we are not given concrete definitions so as to allow people to have some leeway when writing stories and not
have to worry about tiny details. It maybe that P cells are just a class of medicine and not a specific thing as the fact is extended life is a normal thing for most of the humanity in space it would seem.

Cloning , genetic alteration, and life extending medicines are all very much in play for Elite

… but Salvation also used cybernetic organ replacements to live for as long as he did, if I recall the log you used to be able to find at the Bright Sentinel wreck correctly. So whatever progenitor cells are (could even be some form of nanotechnology), it’s not a “simple” immortality device.

Immortality is never simple Kira Goto
You gonna take me up on the offer to look at your internal reciever one day soon?

Uh... no? I don't let Azimuth, so I'm especially not going to let you.

And the subject of immortality is a whole other question. Biologically in particular. Eventually you'd end up more machine than (organic) body, and you might as well replace it with a mechanical form that superficially resembles a normal body. Which I of course don't know anybody like. Or go the way of digitizing your entire mind, but I am definitely not trying to hint at anything that everybody believes he is dead and surely the mind that understood Guardian technology the most could not possibly achieve this...

... how do these idiots manage to seriously convince themselves of that?
