In general all anabolic steroids can and do cause water retention. Some "gurus" have their athletes stop all steroids some time before a comp for this reason, say even 2 weeks out. It's hard to get that very very thin skin on a lot of anabolics, even if it's just tren or winstrol or masteron or whatever. Friend of mine from the gym for example had tremendous bloat from Winstrol. Competing bodybuilders ride that line between fullness and being too bloated vs. dryness/crispness and being flat, trying to find the optimal level. I remember Bob Chicherillo, who I believe is from the Chad Nicholls/Tom Prince school of thought, said only idiots take any steroids the last 2 weeks before a comp because of the water retention. I don't necessarily agree totally but he has a little point.
Some seem to think only estrogen or prolactin or whatever cause water retention but androgens do it too all by themselves... via sodium retention, mineralcorticoid effects etc etc.
