I've always taken serostim before. When ever I use to mix it with bw it would break down and disappear within 1 or 2 seconds after the first drop made contact with it. But , tonight I just got my jino kits and mixed a bottle. To my surprise the hgh didn't melt so quickly. It actually took like almost a whole min for it to completely melt ! Is that normal???? I'm real sure it's good cause I got it from the manufactuer. Could it be that with sero i use bw and with this one I use the water that came with it cause it said that it's good for 14 days with it.
