Orastan-A is an off shoot legal variation of which is structurally similar to an old and no longer available Japanese steroid called Furzabol.

Furazabol, also sold under the name Miotolan, was rarely seen outside of Japan. Furazabol is a fairly potent oral anabolic steroid, with properties somewhat similar to its close cousin Winstrol (stanozolol). This compound is a non-methylated derivative of furazabol, and as a result may share certain functional characteristics to this agent.

There are many different on the market that offer similar results to the original Orastan-A:.


This compound is on the mild side. It's also non-methylated therefore liver issues aren't a usually a concern. It is seldom used for bulking and tends to be more appropriate for recomping (building muscle while losing fat) or cutting. It's also a good compound to stack due to it being non-methylated.

There's a reputation for a unique potency toward increasing androgen receptor density, suggesting it can be used to intensify the anabolic effects of other steroids. Such a connection can't be substantiated by the literature. Any effect it has on androgen receptor density likely mimics those of other anabolic steroids, which may include some period of upregulation.

Overall one can expect this to be a mild to moderately effective anabolic, with low relative androgenicity. It presents minimal liver toxicity, but could negatively affect cholesterol levels.
