It's tough to disagree with filtration and I feel the same way about choosing solid BAC.
I'm curious what others think about filtering peptides versus applying them directly. Another thing on my mind is how one kind of solution compares to alternatives. When going through the filtering process, is the specific solution really important? I've come across comments about certain solutions not meeting sterility standards, so does the filter change the situation? The first container I received from an acquaintance seemed unfiltered and turned out alright, but for the next one I'm ordering, filtering is what I'm going to do.
