Tamoxifen is a time-tested Selective Estrogen Receptor Modulator (SERM) widely used in both clinical and performance settings to counteract estrogenic side effects and stimulate natural testosterone production. Originally developed for breast cancer treatment, it’s now a cornerstone in post-cycle therapy (PCT) protocols due to its effectiveness at preventing estrogen rebound and restoring hormonal balance after a SARM or anabolic cycle.
Tamoxifen works by competitively binding to estrogen receptors in the hypothalamus and pituitary gland, which helps to increase the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This hormonal signal jumpstarts the body’s own testosterone production, helping users maintain their gains, energy, and performance post-cycle.
