when traveling on planes to a destination, will HCg be ok out of refrigeration for 5 hours or so (until i get to my hotel)?

Get one of those chemical ice packs that you squeeze to activate. Place in a ziplock freezer bag and you're set. That's what I do when travelling. You won't have an issue. Just in case, bring the box with the Rx label on it.
thanks dude
Actually there have been studies that show HCG begins to lose potency fairly quickly as it comes to room temp. Someone posted them here quite a while back.
I left the bottle out overnight, and I am positive that the potency remained strong. It's possible that it lost 25%, but no more, and prolly way less. You can also freeze it in the syringes. I've done it, and again, I am certain it works, based on blood work. I just increase dose by 10%. However, this was when I was using it in conjunction with Test. Didn't want to waste the bottle, even though it was free at the time. That's just the way I roll.
my experience is that it degrades rather quickly at room temperature. Keep it in a cooler, Better safe than sorry.
