I never seen a pharmaceutical testosterone, being underfilled... I used Bayer testoviron, sustanon organon , msd and aspen, testovis (all of these bought in my local pharmacy) and always was a 0,1/0,2 ml more. However I never used aburahian test E, but I think that if you noticed that it is underfilled probably you have in your hand a copy of it. Unfortunately There are a lot of copy around , some are bunk , some are good... Regarding the lab test , analyzer always required only 0,2 ml for testing, so he detected the percentage of active ingredient present in 0.1 ml, then multiplied by 10, and obtained the total active ingredient per 1 ml. All this is correct, but if the ampoule is underfilled, you are not getting all the testosterone you should get.
@janoshik what do you think about it?
