Mesterolone 25 - Hemi Pharma

Produced by Bayer and marketed as Proviron, mesterolone is available in over thirty countries, yet it was never approved in the U.S. Known for its anti-estrogenic properties, mesterolone blocks estrogen activity, supporting lean, defined muscle growth in bodybuilders. This non-aromatizable steroid doesn’t produce liver toxicity due to its structure, making it suitable for longer cycles. Additionally, mesterolone’s low impact on testosterone suppression allows it to support muscle density without significant hormonal rebound, making it a versatile agent in both cutting and maintenance phases​.
