Filtering issues, need advice
I just started my rats first journey and I'm trying to filter. The first time I accidentally ordered the 33mm .22 micron filter and it was unbelievably difficult to get the Tesamorelin through the filter. I ordered the 13mm .22 micron and had an even harder time getting the fluid through. It takes all of my strength to get a drop into the vial. With the 13mm I think the filter broke from the pressure and ended up leaking half a vial. What am I doing wrong or what did I order wrong? I am using a second needle as a vent and am following the Peptide Critic YT video where he filters tesa with no apparent issues. you can see where I nearly rubbed the numbers off the syringe from the friction. I checked and it doesn't appear there's even a way to put the filter on backwards. there's a very clear lure attachment end. Thanks all
