Nearly all instructions indicate one hour at room temp?
Imagine having cold water inserted into your veins, etc? Frosty Blood?
IF my IG is too cold? I can FEEL IT travelling up the vein thru my whole! So I always have something warm to dring and something warm to cover me.
You will KNOW when it gets into you when it’s too COLD!
Read the prescribing info for your brand and it’s there.
