"My fitness is coming on. It was frustrating being out for a little bit longer than I had hoped, but I am feeling like my fitness is getting there," admitted the 30-year-old.
"I am getting a bit more game-time, I had my first 80 minutes against Edinburgh last weekend and I am feeling good. I was hungry to get back playing again."
Up next for Ulster and Bowe are Cardiff Blues. Last season Bowe scored two tries at the Arms Park in a convincing 48-19 win for the province, but Bowe believes that Saturday's match will be a difficult test for Mark Anscombe's side.
"Cardiff have had a bit of a turbulent season but they have quality players, a few British & Irish Lions in their team and they are a strong side.
"To play them over there is never going to be easy, they like to play a nice brand of rugby.
"It would be very nice to get a few tries against them again this season, I would love to go over there and score a couple of tries.
"I enjoy playing there on the new artificial surface. The track is going to be very fast, hopefully the rain stays off and we can play some good rugby."
Ulster have won every game that they have played in 2014 so far - including four RaboDirect PRO12 fixtures in the last five weeks - leading into Saturday week's Heineken Cup quarter-final against Saracens.
Bowe added: "We were lucky with the Scarlets match being rearranged. That meant that we have had an extra game to build us up into a tough few weeks.
"I think the match against Edinburgh was disappointing for us, it was difficult to play, very physical and the weather conditions were terrible.
"But hopefully this weekend the conditions will be better and we will be able to play a nice style of rugby with the view to opening it up against Saracens."
