I thought I had added this already, but evidently not. I drew and injected the second injection with a 29g insulin pin. This was S L O W. The 27g I used for the first injection will likely be what I use going forward, but man, I did NOT feel that 29g needle. The logical thing to do is to find a 28g and give that a go, but I have something of a pin surplus right now, so I really should just use what I have.

Mild soreness this morning in the injection area, but no redness or swelling. I can't even feel a lump, which obviously is good. I might not notice the soreness if I didn't know I had done an injection in that spot. I'm calling the GSO good to go, at least after filtering. The next batch I filter, I will use a .22 micron pvdf or nylon filter and see how that works.
