Hey fellas this is probably a newbie question that has been discussed so I appologize in advance. Can you load a pin w/ say 100mcg ipa and 100mcg mod grf keep in a cooler during your workout then inject it pwo? Will it lose some of its' potency? I would think as long as it is being kept at cool temps and is used within a few hours of loading that it would be ok, but I'm no expert... that's why I'm asking.
