Well I thought this would be pretty easy. Just follow the directions of the calculator posted here: http://absinth.greatnow.com/calcpowder2.html
and make up my test enanthate.
I decided to make 10ml at 250mg/ml to start off with. I used this calculator and found out I needed 2.5g of powder, 6.9ml of oil, 0.2ml BA (2%) and 1ml BB (10%). After going through the dissolving and mixing process, then filtering through a .45 filter, I found out that it only made just over 8ml instead of 10ml.
I left 1ml of oil out of my mix, which I later used to purge the filter.
Still all I could get out of this was 8ml!
Has anyone else had this problem? Apparently a lot of people consider this calculator reliable. If it is, where have I gone wrong?
If I add 2ml of oil to my vial now, I won't have 250mg of test E per ml will I?
What should I do?
Thanks.

Thanks, I realized that the venting needle must have been pushed too far in. The oil only started to extrude from it at the end when the oil level in the vial became higher. I only used BB because I wanted to make a thinner and thus less painful solution.
