posted yesterday about how to test your test. I put mine in the freezer for about 5 min. it came up cloudy as i heard. i knew this test was legit cause it was given to me by a friend who gets his for low test levels, so i KNOW this was legit. i came up cloudy. i had other test of another brand and was sceptical about it. put it in the freezer and it also came up cloudy( i am frickin stoked) thanks for input guys!
