Being vacuum sealed doesn't mean you will have an absolute zero pressure in your vial, sometimes it can be light, sometimes it's strong, but all peptides are vacuum sealed during production and you have many reviews about vacuum of peptides in the thread also. Having a strong vacuum in peptides can damage some unlike the HGH, so it is not necessary to have a strong one and sometimes it is not adviced. The engineer adjust the pressure the way he think it's right for the good of the peptide and its sensitivity. Our HGH have a very strong one, so of course if you compare with it, you will find the peptides one weak.Mine doesn’t and others say they don’t
