PT-141, also known as Bremelanotide, is a peptide therapy used to support sexual health and libido. Unlike medications that work through blood flow mechanisms, PT-141 works directly on the central nervous system. It activates melanocortin receptors in the brain that regulate sexual desire and arousal. PT-141 has been studied for...Read More

GHK and GHK-Cu are closely related peptides used in regenerative and aesthetic medicine. While both support tissue repair and skin regeneration, the presence of copper in GHK-Cu significantly enhances its biological activity. Understanding the differences between these peptides helps determine which option is more suitable for specific therapeutic goals.Read More

GHK-Cu is a copper-binding peptide formed when the GHK peptide binds to a copper ion. This complex significantly enhances the biological activity of GHK, especially in skin regeneration and tissue repair. GHK-Cu has been widely studied in dermatology and regenerative medicine for its ability to stimulate collagen production, promote wound...Read More

GHK (Glycyl-L-Histidyl-L-Lysine) is a naturally occurring tripeptide found in human plasma, saliva, and urine. It plays an important role in tissue repair, skin regeneration, and wound healing. GHK levels are highest during youth and gradually decline with age. Reduced levels are associated with slower healing, reduced collagen production, and visible...Read More

Advances in metabolic and longevity medicine have identified several peptides and metabolic regulators that enhance mitochondrial function, improve fat metabolism, and optimize cellular energy production. Among the most promising compounds are SLU-PP-332, MOTS-C, and 5-Amino-1MQ. While all three support metabolic health, they work through different biological pathways and offer distinct...Read More
