Get User Data service

I don’t know if I get Data users in profile.ts or in other component.ts ?
When I get data users in profile.ts the data apper slow, how can use this is data users in someplace the project ?

   getUser() {
     this.userService.getUser().subscribe( user => {

guardUser() : any {
    return this.profile;

so, this stay slow , I trying call data in app.component but I think it’s wrong

I have an authService provider that makes authState available as a BehaviorSubject. pages that need to know authState subscribe to that BehaviorSuibject.

Can you make its available friend ?
