You kinda answered your own question. It says that a single dose only increases your lifespan, not make you completely ageless. So I think that it works like most RL medicine does, regularly take a dosage to keep the effects and be immortal. But by regular I don't mean daily. Probably once every decade, at minimum.

My rough guess is that a single dosage of it enhances your life by 50-100 years. So after 40-90 years, you can take another dose to live another 50-100 years. Doesn't sound like such a bad deal to me, TBH.
