I always leave test enanthate in the sealed plastic bag it comes in. I cut off a small corner section of the bag and then inject the amount of BA that I will use into the baggie through the open corner. Carefully, break up the clumps of test by hand so they the mixture becomes like gravy. Don't spill it. Then, take the top off of your mixing vial and place the open corner of the bag just over the opening and squeeze it in.
