Tamoxifen and bodybuilding
Tamoxifen, a selective estrogen receptor modulator (SERM), is recognized for treating estrogen receptor-positive breast cancer by blocking estrogen effects in breast tissue. In bodybuilding, it’s used off-label to manage gynecomastia, preventing male breast enlargement due to steroids. It helps inhibit estrogenic activity and is used in post-cycle therapy (PCT) to restore testosterone. Despite its popularity, risks like mood swings and increased thromboembolic events exist, urging caution without medical guidance.
