Superdrol has always stacked well with most injectable steroids or other hormones that do not have a c-17aa modification. Keep in mind, your liver would not be able to handle another oral stacked with superdrol. For bulking, deca durabolin and 19-Norandrosta 4,9 diene- 3,17 dione are the best stacked compounds, and for cutting, trenbolone. Since this steroid is particularly tough and hard to breakdown, this product is not recommended for use for any longer than 4 weeks due to severe liver toxicity. Though, some experienced bodybuilders who use N2Guard during the cycle report using superdrol for 6 weeks with good results.
The anabolic efficacy of this compound can be attested to anecdotally on the many forums online where anabolic drug use practices are openly discussed, as can its hepatoxicity (toxicity to the liver). Many cases of liver damage due to the use of methasterone have been cited in the medical literature.     Although the original manufacturer ceased production in the face of possible governmental action, methasterone remains commercially available through over the counter dietary supplement products sometimes referred to as “Superdrol clones” and through domestic or foreign chemical production companies.
