Not new to the peptide world but new to the gh world. Anyone have any recommendations in regards to blue vs black tops from opti? I know labs are number one but has anyone had any quality issues in one vs the other. I’ve seen a lot of talk of milky vials from various vendors. It seems to be isolated to higher iu vials. I think I’ve already decided to go with the blue tops, but just wanted some feedback before I pull the trigger. Thanks
