Ultima-Proviron 25 - Ultima Pharmaceuticals

Mesterolone, introduced as Proviron in the 1930s, has a distinct role in athletic settings for its androgenic effects and estrogen-blocking capabilities. Known to support muscle hardness, Proviron’s SHBG-binding property enhances the activity of stacked compounds by increasing their free, active levels in the body. Due to its structure, it minimally affects liver enzymes, so bodybuilders use it in extended cycles to improve muscle density and avoid estrogen-related bloating. Additionally, its ability to support natural libido makes it a reliable choice during contest preparation​.
