Yes no problem.
GH isn't as fragile as people think I have known many to use expired GH with great results as well as rehydrated GH with BAwater 30 plus days in the frig and get great results.
certainly shouldn't be the practice but those were under certain conditions.
(one guy found a kit he hid from himslef that had been stored at room temp for a year and another guy had rehydrated a vial and left it in the fridge had some family issues and later came back to use it)
a person hypothetically could rehydrate his GH and put it in an clean slin bottle when traveling and be able to get his pins and etc past the security check point and still remain on the cycle)
There is also an option to avoid this one can dose up on the GH as in the ETD protocol or EOD protocol and not miss a beat.
