Bro this topic has been beat to death!!! Ill give you a straight forward answer about GH from a guy who has blown threw about 20kits over the past year or so. If you GH is real it does not matter when you take it! So yes aslong as your preload wont be in the sun light or heat you should be fine, but honestly everyone worries about when to take the stuff.... Do i take it in the morrning? Do i take it at night? Do I split it up a zillion times throught the day to mimmic naty production? Just take it when ever you want its all the same the 1/2 life is so short that you it does not make a diffrence!
Good luck
E
