Nolvaxyl 20 mg – Trusted SERM for Estrogen Control & PCT
Active Ingredient: Tamoxifen Citrate
Manufacturer: Kalpa Pharmaceuticals
Pack Size: 30 Tablets (20 mg each)
Nolvaxyl 20 mg is a pharmaceutical-grade Tamoxifen Citrate product designed to serve two key roles in the world of bodybuilding: controlling estrogen-related side effects and supporting hormone recovery during post-cycle therapy (PCT). Manufactured by Kalpa Pharmaceuticals, Nolvaxyl is one of the most relied-upon SERMs (Selective Estrogen Receptor Modulators) among athletes and bodybuilders alike.
Tamoxifen acts by binding to estrogen receptors, effectively blocking estrogen in specific tissues such as breast tissue. This helps prevent conditions like gynecomastia during cycles involving aromatizing steroids such as Testosterone Enanthate or Methandienone. Additionally, Nolvaxyl plays a critical role in stimulating natural testosterone production during PCT.
For on-cycle support, users typically take 10–20 mg/day at the first signs of estrogenic effects. For post-cycle therapy (PCT), the standard dose starts at 40 mg/day for the first two weeks, followed by 20 mg/day for the next 2–4 weeks depending on the cycle length and intensity.
Nolvaxyl is frequently used in PCT stacks and during cycles involving high estrogen risk. Popular stacks include:
