According to different experiments, different peptide purities can be selected. In principle, the higher the purity, the higher the price. Peptides are compounds formed by the binding of alpha amino acids to peptide bonds, and are also intermediate products of protein hydrolysis.

The purity of peptides refers to the content of target peptides detected by HPLC analysis at 214nm (214nm is the absorption wavelength of peptide chains); In addition to the target peptide, impurities that can also be detected by HPLC include: missing sequences (target sequences with one or more amino acid residues missing), truncated

With the growing maturity of biotechnology and peptide synthesis technology, more and more peptide drugs have been developed and applied in clinical practice. Peptide drugs are widely used in the prevention, diagnosis and treatment of cancer, hepatitis, diabetes, AIDS and other diseases due to their wide range of indications, high safety and significant therapeutic effects.

The core of healthy weight loss still lies in establishing a calorie deficit. It is recommended to prioritize adjusting dietary structure (such as increasing protein and dietary fiber), regular exercise (150 minutes of aerobic+resistance training per week), and consider medical intervention if necessary. If considering the use of peptide drugs, a comprehensive metabolic assessment should be conducted through endocrinology or professional medical beauty institutions.
