HELP ME BEFORE I DIE

Here's the story. I have some long igf1 from Australia. I dissolved it in what I believe to be 10mM acetic acid just as the directions say to do. I went to inject 20ug of the long igf1 with 1ml of distilled water and as I started to push down on the plunger I got this insane burning feeling at my injection site. It seriously felt like I was injecting acid into my body. Each time I went to push more of the stuff into my body the sharp pain began. So I took out the needle, no blood was present so I knew I did not hit a vein, and injected into another spot on my body (quad) and the same pain began again. This was an insane burning feeling.

I have never injected water based steroids into my body so I dont know if it is the water that burns or is my long igf1 solution too acidic. I first put 1ml of distilled water into my syringe and then sucked up the long igf1 into the syringe, so this stuff is getting diluted. There is no pain or redness around the sites as of now (20 minutes after injection), so maybe I am just a wimp. Please advise me about this situation before I do another injection after my workout tomorrow. Thanks.

Oh yeah, the igf1 has been in the refrigerator so it is cold, but the water has been at room temperature. Also, the water may be deionized water, not distilled water. My friend gave me the water from his lab and it could be deionized so I dont know if that would make a difference.

My igf-1 came premixed and all I had to do was add bact water in the syringe with it. I did experience burning a little but no too bad. It could be a strong mix but I'm not sure. Hope you get good results from it., in 4 wks I did not notice SHIT!

Mine came mixed already. You will feel a little pain though when injecting.
