I think the freezer test works with testosterone but I may be wrong. I know for a FACT that real testosterone clouds up when in the freezer for like 5 mins. My buddy got fake stuff before 100% fake with no resluts at all, and that stuff stayed clear as water. Who knows, maybe the different brands were made with different ingredience and that is why. Who knows.

So this might work with test. Or you could get it tested at a lab, but not sure how or where.
