what compound(s) will you be pushing through that size pin?
depending on what it is, you may want to warm up the loaded pin a bit (personally, i will put the loaded syringe on the top of my stove...nothing is turned "on" but my pilot lights make for a warm surface. i leave it on top for about 5 minutes, change pins so everything is sterile and then fire away) so the oil can flow quicker.
i noticed a big difference between a 22 & 23 as far as how long the actual inject took because i had to really "work" the 23 in order to get it to flow
I just did a 2 cc shot with 1 tren and 1 sustenon...will see in the morning! I did it with 23 g 1 inch...next time will try 25 g 1 inch (forgot I had them). Just stinging right now....Gonna throw some ice on it
