Not as concentrated as AAA rose, but considering price, It is a good option if you wish to dose throughout the day. The real concentrated Blue Emerald is certainly 4 or 5 times the AAA rose, but for my general supplement use , this purchase is ok….it allows me to make small doses frequently, which I like. Batch to batch variability is a reality for these mineral preps because there is no reliable analytical method (yet) to allow standardization. Since the monoatomics are in a high spin quantum state, it makes sense to acclimate the vial to your energy fields, which makes perfect sense to many of us.
