The Igf in the bac water has most likely broken down by now. It would not react with the CJC-1295 anyway. No need to worry about that part of it. But like rusty said there may have been some contamination there. Trust me from personal experience that you do not want an infection! Get some new bac water.

This is some info I researched just for the hell of it. It explains that you can shoot two different peptides in the same syringe without any reactions occurring. And that peptides should not be stored for too long. Also that you can prepare multiple syringes for the day as long as sterile practices are used to transport them. And why you should be gentle with your peptides while reconstituting.

Peptides are compounds formed by 2 or more amino acids that are linked together. They are linked together by what are called "peptide bonds". They are what hold the amino acids together. Peptide bonds can ONLY be broken down by two processes. 1 - Hydrolysis - The breaking down of a peptide bond by adding water. Don't freak out lol it is a VERY slow process. That is why there is a shelf life on peptides once they are reconstituted . 2 -Denaturation - which is exposing the peptides to strong bases or acids, heat, salt, shaking, radiation and solvents.

It might be ok since the BA is good at keeping it sterile but why risk it? A bottle of bac water is incredibly cheap. I would trash it and get a new one
