Accessing conditions from DSolve

I have the function from a DSolve result, however, it comes with two conditions. One on ‘n’ and one on '[Mu].

My questions is how do I access and use these requirements to plot my function correctly without explicitly copying the conditions each time I get a different function?

I need to assign ‘mu’ from the condition and also know if n starts at 0 or at 1, that’s all.

Cheers, Paul

You can try the option GenerateConditions->False
