Rubrosterone

An ecdysteroid isolated from Achyranthes rubrofusca - a traditional medicinal herb.  Rubrosterone differs from other ecdysteroids used in bodybuilding supplements, as it lacks the side chain present in 20-hydroxyecdysone and its analogs.

There is virtually no accessible human or animal research on the effects of rubrosterone in isolation – thus, claims that rubrosterone is “more active” than other ecdysteroids are premature, at best. One study demonstrated Achyranthes rubrofusca extracts exerted hypolipidemic effects in rats, although what contribution – if any – made by rubrosterone is unknown.
