2) I have small plastic box to store them, which I'll clean with alcohol swipes before storage. Should I store in the fridge or in a cool dark cupboard?

3) If answer to #1 is to use new draw pin each time, do you suggest recapping with the injection needle before storage, or swapping it before injection (leaving stored with the 18g draw pin).

5) Feasibly how long can these pre fills be stored? Test E, Castor Oil + BA

Thanks!
1) Just draw up the total amount you need for all 5 pins, then put an equal amount in each pin.

2) Testosterone does not need to be refrigerated, water based items do. I store mine in a tall shot glass, needle side down. I make sure to leave about .02 of air next to the stopper to push everything out through the needle.

3) I use a single pin to draw everything, and I use an insulin pin for drawing. Draw into an insulin pin, then use that insulin pin to back fill your capped injection pins (which are also insulin pins). Store as defined in 2 above.

4) there is no four. Fibonacci FTW!

5) Feasibly? I would not hazard a guess. I do one weeks worth of pins at a time. Further, I leave a little air (see 2 above) between the stopper and the oil, both to push out all oil and to reduce the chance of stopper degradation. I don't really know how big a concern that is.
