I got some cottonseed oil from research supply, and in the pic on the site the bottle was sealed with a rubber stopper. But what I got was in an open bottle.
It says "This oil has been filtered through a .22um sterile filter"
but like I said, you open the the bottle and it's "open" no rubber stopper. Going to be mixing it 1:1 with test-E. Will the BA in the test keep it sterile? Don't want my rats getting sick...
