repeating elements in a list

Hello,

suppose I have list

lst={A, B, C}

and I want to create a new list, where all elements are repeated n times 
so that (for n=3):

newlst={A, A, A, B, B, B, C, C, C}

I have the following code to do this:

n=3;
newlst=Flatten[Table[Table[lst[[i]], {n}], {i, Length[lst]}]];

but I'm pretty sure, that there must be a more elegant way to solve the 
problem.


thank you
