Of crucial importance to a person with ALS/MND is the fact that there will be no cure approved (even if one existed right now) until after the expected life span of some 90% of PALS.

​​ RCH4 may statistically increase life expectancy by ~ threefold or far more, although we do not make any claims, nor offer any interpretation of our clinical data which is provided by PALS themselves worldwide.​
