Anyone bought ILP here ? Mind to share the investment portion return% for the past few years?

What's in my thought is if the return of ILP is lower than my investment, i could buy a pure protection product, and withdraw my investment in the future to cover higher premium cost.
Usually when insurance agent promoting their ILP product, they only give illustration of a normal scenario and best case scenario % return, and i dont know whether the % return they claimed is true?
