Description
Benefits
- Blocks estrogen activity at target tissues rather than suppressing estrogen production
- Commonly used to manage estrogen-related effects such as gynecomastia
- Supports recovery of natural testosterone signaling post-cycle
- Helps stimulate LH and FSH release through hypothalamic signaling
- Preserves endogenous hormone production
- Frequently used in bodybuilding and performance hormone protocols
Background and History
- Tamoxifen was developed as a selective estrogen receptor modulator (SERM)
- SERMs work by blocking estrogen receptors in a tissue-specific manner
- Tamoxifen has long been used in estrogen-sensitive conditions due to this selectivity
- Its ability to block estrogen feedback at the hypothalamus increases gonadotropin release
- This mechanism made it useful for supporting endogenous testosterone production
- In bodybuilding and performance settings, it became a cornerstone compound for estrogen management and post-cycle recovery
