impurities matter it may include degraded HGH fragments that are biologically inactive but could cause injection reactions or immune issues, reducing net effectiveness beyond purity alone.
As I have said, I don't really care that it might not be BAC, I have used WFI for the CJC/IPA
I would prefer to use BAC as some customers have a vial forn45days and some even stretch to 60.
My problem now is, if it's not BAC, then I'm using space for water in he shipping which I could use for peptides.
So as I can't get BAC locally, It would be great to know if the BAC is in fact BAC...... For now I'm going to blindly assume it is🙈
