Nah, I wouldn't worry about gyno, you're not even using 4ad and its only a PH cycle, unless you've been "on" for a long time, when I mean long, I mean 8+ weeks. Clomid will just halt your gains...trust me, during everyones cycle we experience puffyness by the nips. It goes away post cycle. If you are scared about gyno, I'd go with nolva instead of clomid.
