[R] Additional polymath query

Yesterday, I asked:
	I have a polymath label for a graphic:
		bquote(AUC[0-infinity]~(ng/ml~x~hours))
	I would like the “x” to be replaced with a bullet.  

David Winsemius provided an answer:
	%.%
(which is also known as “cdot”)

That works but the dot is small — I would prefer something bolder.  
Further searching led to the following:
	plot(1, xlab="\u25CF") 

Now I can’t figure out how to incorporate
	\u25CF
into the original command (to replace the “x” below):
	bquote(AUC[0-infinity]~(ng/ml~x~hours))

As much as I enjoy plotmath, it remains a bit of a mystery to me.  Any advice would be appreciated.
