It shouldnt compromise it much if at all as long as its not reconstituted...
Shipping is fast and only a few days, if you left it at room temp or higher for longer than a week or so then maybe but I wouldnt worry too much about it.
If the shipping was that big an issue every sponsor would ship with a cold pack in styrofoam containers[/QUOTE]
No they are under no obligation to provide this. It's an easy solution and something every pep-tide sponsor should consider providing it's customers - the cost is minimal for an ice pack and package - much like Osta used to do.
