After 2-3 years of Sculptra injection with no touch ups, does the butt just return to its pre-sculptra state ?

I want to know what happens after you get Sculptra, if the results just leave after a few years & the butt returns to its original state(before the injection). I would also like to know, if you continually do resistance(weight)training for your glutes even though you've gotten Sculptra injections, would your glutes still be able to respond to the training(grow)?
