Did my first round of injections this morning. Everything went well, can't wait to feel effects. I did forget to clean the septum on the HCG vial when mixing in the biostatic water. I remembered for the injection needle though. I hope that is not too big of an issue as long as I remember in the future. Just nervous I guess Also glad I choose to go with a 29G 1/2" (in the delt) needle for testosterone instead of the 25G 5/8" that was suggested. It does load a bit slow, but not horrible. I used 30G 1/2" for HCG (in abdomen). I would not be near confident enough in self injections with out this site.
