GHK-Cu works by stimulating collagen synthesis and tissue remodeling biological processes that produce gradual, cumulative results rather than overnight changes
A method for isolating a peptide, the method including purification of a GLP-1 peptide from a mixture comprising said peptide and related impurities via an anion exchange chromatography process, the anion exchange chromatography process comprising the steps of:separating said GLP-1 peptide and said related impurities of said mixture by elution in a solution consisting essentially of an organic modifier, water, optionally a salt component, and optionally a buffer, with a linear or step gradient or isocratically in salt component and/or with a linear or step pH-gradient or at a constant pH-value, wherein the pH-gradient or pH-value should be in the range where said peptide has a negative local or overall net charge different from the local or overall negative net charge of said related impurities so as to remove said related impurities;and subsequently, if necessary, subjecting to analytical tests and/or further purification, and isolating said peptide in a conventional manner, wherein the ratio of organic modifier to water, on a weight percent basis, is from 1:99 to 99:1, such as 1:99 to 80:20, 20:80 to 80:20, 30:70 to 70:30, 35:50 to 50:35, or 40:50 to 50:40
This limits the primary vial to one or two punctures and eliminates repeated contamination exposure
