I'm in the same boat as you u571, I have a small lump in my left pec, that's also refused to shrink down. I don't really know when it showed up either, as I didn't experience any pain, itching, etc. I suspect it was during a 2on/2off/2on m1t cycle I did, most likely during the second time on m1t when natural test levels were low. I'm performing pct from a different cycle, and am thinking of extending nolva dosing at 40mg for 2 weeks, instead of just the initial 2 weeks at 40mg and tapering to 20mg on week 3. Would the nolva do any good at this point in shrinking the lump months after the initial growth likely occured?
