oh and another piece of advice that has helped me throughout this cycle.
since injections are daily (75mg/day for me) with Fina, you're gonna feel like a pin cushion and it sucks when you're sore from previous injections due to the heavy oil that fina sits in..
here's what has helped me...i would draw it up with a 23 gauge pin (easier to get the oil based fina into the chamber), then unscrew the syringe off and place a 25 gauge pin into it...so the "hole" isnt has big when you throw it into your skin...therefore less soreness and pain..just push slowly into your delt, bicep, glute, or wherever you inject..and trust me, you're gonna want to use every injection site possible with the daily injections..
