So I'm having the same issues as everyone else as far as pinning multiple times and dull needles. My solution was to reconstitute one vial of cjc and draw the entire vial up in one slin pin then reconstitute the ipam and draw it up in one slin pin. So now I have 2 slin pins both full. So when I pin I just backload one slin and then put both full slin pins back in fridge. My question is, is this safe to do and I want to make sure I'm not degrading the peps by storing them in syringes. Any of you guys do it like this or have any input?
