That is what the syringe filter is for.....to catch the "gunk". As for the conversion itself, you have to assume there will be some % loss of the TA. You will have to do a search, as it has been discussed ~% gets lost. I just know you don't get the whole 2,000mg. But once the TA is mixed in the oil it is one saturated solution.
Here is a stupid example but if you coffee-filtered Kool-Aid, would water come out the other end leaving the sugar and coloring left behind?? LOL
BTW, as a precaution I use 2 syringe filters and get a clean golden solution. Painless injection, no infection, and a solid 10-lb gain so I must have done something right.
