The Pirates have bounced back from the loss of star striker Rickie Lambert to win four of their opening six games - a sequence that has taken them to fourth in the League One table.
But Trollope still wants to add further depth to his squad now that the loan window has opened.
"We are in discussions with a number of players and agents," he told the Bristol Evening Post. "It is never easy, because some of our targets are highly sought after.
"We are doing everything we can to add one or two players and we are hoping to do something before Saturday.
"The situations can sometimes be quite delicate, though, and if we can't do anything before we play Oldham, then we will want to tie things up next week."
