Hi guys, I'm not sure If this is the right section, but I figured that since this was more about containers instead of the contents, this is where I should put the topic! Well so its encouraged to inject igf/insulin immediately PWO to get best results from it. The problem is, how do u manage to keep those cool in your gym bag ( assuming that your gyms far from home ). Yes I've done some searching on the internet, there are some "cooler packs" which claim to keep insulin cool for 48hours or more, with JUST tap water! I mean, I don't know if those really help keep them cool or not, but it doesn't seem feasible to me. I was thinking more of a battery operated cooler box which would actually make some sense in keeping contents cool. Well, what do you guys use for your peptides/insulin??
