What is the best to use for mixing peptides??

I have HGH, IGFLR3 and CJ to be mixed. They are generic and have larger amounts in 1 vial.

IE: IGF has 1000mcg in one vial so I can't separate it, I have to mix it all in one shot.

Is mixing with bacteriostatic water and keeping in the fridge for 4 weeks going to cause degrading??

Please only reply if you know 100% for sure, thanks.
