Test cyp and Winstrol?

I've been on 250mg a week of Test/Cyp for sometime now prescribed by my doctor. My natural production is not so good these days at 41 years of age. I've been working out consistently since i was 17 and have a good natural base and have made slight gains from the Test. I'm looking at adding some winstrol to gain some size and strength without making it too obvious. I don't want to use D-Bal because of the water weight and bloat. My question is this...Will Winstrol give me any size and strength or just cut me up? I want to look good for the Summer and summer months to come. Would i better off with D-bol? Any general thoughts on this would be greatly appreciated...
