What I did with my IGF was to carry only the syringe with the IGF in it, along with my wrapped alcohol pad and my bacteriostatic water. I put the cap back on the needle and a small aluminum paper "spacer" between the plunger and the syringe in order to keep it from accidentally discharging in my gym bag. I put this together in a sunglass "holder" (Damn, I'm sure there is a real word, now you can all tell that my usual language is French) and carried that to the gym. Is it work? Yes. But then again, I figured for the price IGF-1 goes for, it was worth it. Poobah, are you feeling that you are getting every bit as much out of your IGF injecting over 30 minutes after training as if you were injecting right away? You do the IM in the muscle group just trained?
