peptide injections slightly burn??

[fish014]

i've been using peptides on and off for about a year and a half. i just purchased a whole new stock of Ipamoreln and Mod Grf. up until now i haven't experienced any unpleasant effects during injections, but every injection i have made since reconstituting the first vials from this new order has burned at the injection site, nothing too painful, but it's something i never noticed before. now i'm wondering what is different about this batch? i am dosing the same amount that i always have (100mcg) of each. what does this mean? are these peptides impure? was the potency of my previous peptides not as good for some reason. what is normal for you guys? is it supposed to burn???

In my experience, sterile water stings and bacteriostatic water does not.

Use bac water for everything. If you do nothing should burn.
