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.
About the author
Bill Roberts is an internationally-recognized expert on anabolic steroids and performance-enhancing drugs (PEDs). He received a bachelor degree in Microbiology and Cell Science and completed the educational and research requirements for a PhD in Medicinal Chemistry at a major American university.
Bill entered the nutritional supplement industry prior to completing his doctoral thesis but his education was invaluable so far as being able to design/improve nutritional supplement compounds, since it was in the field of designing drug molecules and secondarily some work in transdermal delivery.
His education was not specifically "geared" toward anabolic steroids other than expertise with pharmacological principles having broad applications. This has allowed Bill to provide unique insight into the field of anabolic pharmacology with knowledge of points which he would not have known otherwise.
