What is Tamoxifen?
Tamoxifen citrate, better known as Nolvadex, is a selective estrogen receptor modulator (SERM). It is used during steroid cycles to combat the estrogenic side-effects of anabolic steroids during cycles and for post cycle therapy (PCT).
How Does Tamoxifen Work?
As a SERM, tamoxifen targets a specific part of the body, being noted for its ability to target breast tissue development. As a result, it’s very popular for preventing or reducing symptoms of gynecomastia (i.e., male breast tissue development).
It works by binding to estrogen receptors around the breast, preventing estrogen production around this portion of the body. While used traditionally as a breast cancer drug, tamoxifen’s ability to block estrogen function around the breast helps to prevent gynecomastia.
Tamoxifen also useful for balancing natural testosterone production by encouraging higher production of luteinising hormone.
How to Take Tamoxifen?
While it is often used during a steroid cycle, it only reduces or prevents breast tissue development when using anabolic steroids, so won’t block estrogen levels like an aromatase inhibitor (AI).
A four-week cycle of tamoxifen for PCT can help regulate natural testosterone production that is disrupted by anabolic steroid use. A daily dose of 10-20mg of tamoxifen is recommend for 4-8 weeks for PTC.
