Ive seen a few people asking about pre loading their syringes etc. The two golden colored were found in my stash as I seem to have misplaced/forgotten about them for months. The end result due to the BA, BB, and other factors led the plunger to deform and on some level deteriorate. If you look at the new syringe next to them you can see how the plunger should look. IMO there is no issue if your oil has been sitting in a syringe for 1-3 days but past that I wouldnt feel comfortable with injecting it. There is no noticeable rubber floating or mixing in with the oil but I cant see on a microscopic level, Just stay safe.

Yes, these are 5cc syringes, it makes injecting multiple compounds sooo simple. Thanks!

Edit: these syringes were not because i preload but because i anticipated injecting that day and honestly forgot about doing so. Life happens, you get side tracked.
