jk, im 18 and ive never taken steroids, but i think i have gynocomastia. Ive had a sore lump under my left nipple for about 3-4 months that has stedily grown. I also have had one growing under my right for about 1 month. If I consulted my doctor could he prescribe nolvadex for me? This same thing happned to me in 8th grade and it went away. If this goes away, does that mean that if you get gynocomastia due to steroid usage, that too would go away?
