I hate SERMS so I tend to rely on the natty stuff- Bulbine, Avenocosides A & B, Bulgarian Trib standardized for Protodioscin, & Stinging Nettle have all been helpful. DAA has some studies to back it up but the explosive diarrhea ain't no joke. I'd just ordered some Humanatrope as well. I can't tell you anything about it from experience but it sounds promising.
