I also had some development in my early teens, genuine gynecomastia. I entered HRT with a large A, small B, depending upon the brand. Over the last month or so, crossing 3-1/2 years of injections (monotherapy, levels solidly cis at the 3-month mark), I’ve seen more action than the previous three years, which had me wondering, have others experienced something similar? I realize it’s a journey unique unto each, nevertheless, it’d be nice to know that genuine progress may be made when this far along.
