This has piqued my interest because ecdysterones are anabolic but don't effect androgen receptors. Assuming PFS has screwed up androgen receptors (which I do), this could be especially helpful for putting muscle back on (if that's an issue).
Some of the herbs (black ant, suma root, maral root) are high in ecdysteroids. A pure ecdysterone extract would lack some of the other benefits but surely be more anabolic.
