I always keep my raws in the freezer!!! Oxidation happens quicker at warmer temps!!! If kept in the freezer they will last MUCH longer than at room temp!!!
Secondly, If your test has particulates settling then I suggest you retest your Test E again as Test E always has a very distinct Piney fruity smell!!!!!
The Test E is VERY VERY hard to make crash, so if it is crashing then there is a major problem somewhere and you will have to first CONFIRM that you know the substance IS IN FACT TEST E!!!!
Then at that point you will need to run down your exact process step by step including your Exact heat, length of heat, filter type and temp during filtering, EVERYTHING cause Test almost can convert with no heat!!! How was your stirring? What steps did you take when adding your wets and powder? What temp when added? Quantities you used with all your wets and your powder???
