Gynecomastia is the build up of glandular tissue under the breast, and is considered an oestrogenic side effect from the use of steroids. When the body senses too much testosterone or a testosterone like substance, it will try to reduce the level by a process called aromatization. This process converts testosterone to estradiol, an estrogen like substance. Early symptoms of this side effect include puffy, itchy or sore nipples. Gynecomastia can range from a mass under the nipple to fully developed breasts.
Not everyone who uses anabolic steroids will get gynecomastia. Since younger individuals are already experiencing a roller coaster of hormones, the onset of gyno due to steroids might be especially difficult to handle. Many people get gynecomastia from steroids such as Dianabol and Anadrol due to water retention in the body.
Some may be prone to gynecomastia while others will never experience this effect. Each individual has a different tolerance level with any substance taken. If you start feeling sensitivity around the nipple area you may want to lower your steroid dose. Those who don’t recognize the early signs of gyno take the steps to treat it, may need surgery down the road.
