Megagrisevit (clostebol acetate) appears to be approximately as effective as Primobolan (methenolone) per milligram or moderately more so. The primary reasons for not using clostebol acetate are its excessive cost and low concentration per mL, requiring large injection volume. Clostebol may have antiaromatase activity.
Clostebol acetate is the chemical name of active ingredient in Megagrisevit mono. Megagrisevit mono was a registered trademark of Pharmacia GmbH in Germany and/or other countries prior to cancellation.
