oh yeah, PS... when you're using liquid bottles, you're really paying a convenience premium on the price. So do take some time to look at the dosing per ml and price per ml (ie total treatment volume of the bottle for the price). So you're looking for maximum dosing efficacy per ml for the best price per ml, but I personally avoid lesser brands as they may or may not have more variance in their manufacturing quality control.
