This discussion compares tripeptides, exemplified by the well-studied GHK, with larger peptides such as the cyclic heptapeptide CyRL-QN15, the human cathelicidin-derived antimicrobial peptide LL-37, and the peptide Andersonin W-1 (AW1), containing 7, 37, and 72 amino acids, respectively [25, 67, 68]
Adenosylmethionine decarboxylase 1 activity is regulated by product inhibition and allosterically stimulated by putrescine
This allows for a dose-dependent relationship to be established, as well as allowing the authors to gauge what dosages will affect micro vs macro level measurements
70% of cancer-related genes downregulated At 1 micromolar concentration, GHK-Cu suppressed metastatic colon cancer gene expression and downregulated 70% of 54 human cancer-related genes examined
In Saudi Arabia the most frequent variant is the Mediterranean one, with frequencies that oscillate between 0% and 0.4% in men and 0% and 0.2% in women
Many advanced hair formulations include both peptides for complementary benefits
