All I'm saying is that I really appreciate bottle top filters since I've used a syringe filter for the first time, recently.

You change the filter? Also, there is a lot of variety in the cleanliness of some people's powders. I've seen people post many problems like this. One compound is great and the next is filthy. Pull apart the two filters (if they aren't gone already) and look at the filter inside. The Tren one will probably look like muck.

mranak is right also. Bottle top/stericup filters are much easier and not too much of an investment.
