Gyno lump, help please!

[Typo]

I've been on for a few years blasting and cruising but never had gyno issues.

My last blast was 600 deca with 600 test e and on the 12th week I noticed a hard slightly painful lump.
I stopped the deca 3 weeks ago and am back to cruise dose with the test.

I ran prami and adex throughout. I have nolva on hand but no sure if I should use it. I also have letro on it's way.

Any idea's how I should combat this?

Thanks in advance!!
