@beachesanddreams Inject cold, u can’t even feel the temp at all. Then you can keep it longer than 30 days. That is what I have been doing for 15 months now because some days I have a lot going on and I just don’t feel like doing the 80 and having the faster heartbeat. Seems to me if ppl are taking it out of frig for half an hour it defeats the purpose of cold/using pen longer than 30 days. As far as temp when injecting, sometimes it stings but mostly I don’t feel anything. I think it just depends on if you happen to put it in a more sensitive area by chance.
