So I'm 20 years old 6ft 174lbs and began taking trt injections in De***ber. Since then I have gained about 20 lbs most of it being muscle. The only area that I have gained fat accumulation is my chest, specifically my right chest. The rest of my body is very lean and striated. I do have a small lump under my right nipple and I know it was caused by high estrogen because initially I wasn't started on any AI. I have since gotten my estrogen under control and I'm aware that the lump is most likely permanent but is there any chance through a strict diet and exercise program I can reduce the fat in my chest? Thanks for any advice in advanced.
