put the coffee
filter inside a small plastic funnel (like a small oil funnel-make sure it's clean too) so it has some structure. Then put it over the vial. After pouring the unfiltered tren into the
filter, let it run/drip through the
filter into the vial. After this process is complete, you are ready to
syringe filter it. However, this is just a quick overview. There are written directions if you search the site.
hope this helps
