I have noticed that when I add 2ml of BW to 10iu vial of hgh I usually ending up getting more fluid, around 2.3mls in total fluid decreasing my dosage when unaccounted. When I thought I was injectin 3iu's at the 60 unit mark, I was actually only getting around 2.7ius. I figure the hgh powder would have to be accounted to be able to get the desired dosage per iu. Has anyone else had this problem or am I doing something wrong?
