Nota bene: bac water guarantees total sterility whereas PBS does not.
By around 3 weeks an originally 99% vial of ghk-cu, if reconstituted in bac water, will get to around 65% purity. With PBS you get to around 85% by that time.
To illustrate: suppose you reconstituted 50mg of ghk cu with 2ml bac water vs. 2ml PBS. Suppose you injected 10 units daily, a dose of 2.5mg, meaning the vial would last 3 weeks.
If you do a linear regression analysis on both, with the bac water solution, after 3 weeks, 41.25mg of that ghk cu would ultimately end up in your system vs. 46.25mg of the pbs solution. Moreover, if you did a dose higher than 2.5mg daily, as many here do, the difference between the two would be even smaller.
You are looking at trading a loss of 3-5mg over a month for a guarantee of perfect sterility and much more practicality. It's essentially doing gymnastics for little gain for most people.
But I can see how if you are prone to injection site pain you might consider PBS to make the injections marginally less painful towards the end of your vial(?), since the hypothesis that the slightly higher free copper ions you get from slightly accelerated degradation in the bac water solution is what causes the pain is plausible if unconfirmed.
