ok guys quick question. I have like 5 bottles of prop and at the bottom of everyone of them they are crystalized. I have already boiled them and they got a little better but im just using them as normal. Since there are crystals at the bottom that im not getting use of does that mean the prop isnt as strong? Some people told me that the crystals at the bottom are the compound that i need and since im not getting them that the peop isnt as strong as it should be.
