I am with Rickson and some of the other guys here, hard to believe if you are running armidex. Try upping it as most say.
I have heard of guys getting gyno from just 2 days on dbol. Some guys are really sensitive to the DHT, and bloating that dbol gives. Nolv will take away the lumps if you have any, and also help with the nips being itchy and painful. Test Prop gave me the same symptoms, I had to up my Nolv to 80mg a day just to keep the gyno down. Be sure and not take to much armidex, I made this mistake one time, and my hands and arms hurt so bad, I coulnd't even grip a bar or anything for that matter. Felt like I had arthoritus in both of my arms. found out it was to much armidex.
Anyways, I would also recommend you upping your test. IMO 250 of test isn't gonna do anything. Again in my opinion if you are running deca, I would run the same amount of test or close to it.
Watch out with that high of dosages of deca, gyno from progestrogen build up will and can happen, and armidex, supposidly will do nothing for it, neither will Nolv. Also the dreaded deca dick, that comes with it, you are running some test with it, but it may not be enough even to help with the DD.
Okay now I am rambling. good luck bro!
