Thanks for all the feedback. I waited a while to reply as I ordered some BS water, and had to wait for it to arrive to test. I had some issues with just plain IGF in the AA it comes in - when I injected SQ it caused me some damage at the site below the skin. I have really sensitive skin, so this could be totally down to my body type. The BS water has made a big difference. I load with IGF first then put about 5 times the amount of BS in the 0.5ml syringe too. It doesn't mix well with the IGF, but my thoughts are that it helps dilute the AA (which is what is causing me problems) once they disperse under the skin. It stings less too.
