I also pre load just About eveyweek. Set my test and whatever im blasting at the time. Gh for morning and night refrigerated obvi. Just dont leave anything in the heat or pin down, ive had some oil leak out
I personally wouldn't put anything in the freezer that we use... aas, pins, hgh, peps etc.
I don't see the harm in storing aas in pins. I personally never have as it takes 60 secs to inject. Even when I go away for awhile I take the pins and a vial separate. Although I know guys to travel with filled pins and again no big issue. I personally wouldn't store them for long periods even if the above is true.
