Proviron (Mesterolone) – Libido, Estrogen Control & Hardness
Proviron (active ingredient: Mesterolone) is a powerful oral androgen used in bodybuilding for its anti-estrogenic properties, libido enhancement, and ability to promote dry, hard muscle definition. It is a DHT-based compound that does not convert to estrogen, making it a popular support drug in cycles and PCT.
At Steroids EU, we offer pharma-grade Proviron from EU-certified brands with discreet shipping across Europe and guaranteed authenticity.

Unlike Arimidex or Aromasin, Proviron does not reduce estrogen production. Instead, it prevents estrogen from binding to its receptors while increasing the free testosterone pool. It’s milder than AIs but also better tolerated for libido and mood support.

- Can Proviron be combined with Arimidex?
