I may not reflect other's experiences/ but at first nothing helped; later after fasting and cleansing and a couple months, maybe 4... after randro and 4andro; I feel herbs SUPER STRONGLY. I can't really describe how "each" feels, but I think you can potentially "feel" it in one dose (if it works for you), like in a sizable dose or even 1tbsp in black coffee (or tea, possibly safer less cortisol and NE effects, plus theanine - dopamine effects). -I think* it does build up in system tho/ need to cycle it, esp in conjunction w/ other herbs (estrogenic, or anti estrogenic, and or androgenic herbs, anti prolactin herbs, etc). --Lots of Indian Medicine, Chinese Medicine, and S. American Herbs too (*'Traditional Medicine*)
