GHK-Cu Peptide: Benefits, Uses, and What the Research Shows

GHK-Cu Peptide: Benefits, Uses, and What the Research Shows

GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring tripeptide found in human plasma, saliva, and urine. It declines with age — significantly so — and this decline correlates with reduced tissue repair capacity, skin quality, and immune function. It has one of the most extensive research bases of any naturally occurring peptide, with

Peptides for Weight Loss: What Actually Works

Peptides for Weight Loss: What Actually Works

Several classes of therapeutic peptides are studied for weight management, and they work through very different mechanisms. GLP-1 receptor agonists like semaglutide and tirzepatide target hunger signaling and metabolic regulation. Growth hormone secretagogues like ipamorelin and CJC-1295 influence body composition by promoting lean mass and fat metabolism. And peptides like

What the Ozempic Halo Effect Means for Peptide Therapy

Semaglutide generated $29.3 billion in global revenue in 2024. It has been featured on the cover of Time magazine, debated in Congress, and discussed in conversations that have nothing to do with diabetes. Along the way, it did something unexpected: it made the word "peptide" a cultural

Peptides for Hair Loss: GHK-Cu, TB-500, and What Works

Peptides for Hair Loss: GHK-Cu, TB-500, and What Works

Hair loss affects roughly 50 million men and 30 million women in the United States, and interest in alternatives to conventional treatments — minoxidil and finasteride — is substantial. Therapeutic peptides have entered this conversation, with GHK-Cu and thymosin beta-4 attracting the most research attention. Here's what the evidence actually

Peptides for Skin: What the Science Actually Says

Peptides for Skin: What the Science Actually Says

Peptides for skin are one of the most marketed categories in both cosmetics and clinical medicine — and one of the most misunderstood. The term covers everything from collagen supplement powders to injectable compounds with clinical-grade biological activity. Understanding the difference between these categories, and what the evidence actually supports, is
