I wish I had pics. For some guys who have been more naturally pre-disposed to man boob issues, I find that it is more likely they will have a problem on cycle. I know you said there is no lumps, but if you were to feel around, I do wonder if there is any form of a lump that is small and so far gone undetected. Feel for something that might be small, the size of a pea. For future reference to anyone in a situation where pics could help, if you think pics could help me, you can always post them at an image hosting site and post the link in your message to me. That being said, to be safe, I would start out by switching to Adex. I find that it is a lot easier for controlling estrogen than Arom. With Arom, I feel like some guys need a lot. If you are sensitive, 12.5mg EOD is not going to be enough. I bet that you need more like 25mg ED. But personally, I would cut it out and swap out to Adex, 1mg EOD for your situation and if nedded, increase.
Also, really it might not hurt to cut the deca out until you have this under control. Thats just the way it works. We know that test and EQ both are test based drugs so you can deal with gyno from them in the same way. Deca is a 19 Nor though and if it were causing any sensitivity, you would need to deal with it in a different way. So if you stopped the deca and ran adex at 1mg EOD, then watch your progress. Once you are certain that you are good to go, you could add the deca back in, if you liked. Then if a problem comes up from adding deca back in, you could try adding caber at .5mg 2x wk
