Mechanism of ActionBPC-157 modulates the nitric oxide system, promotes angiogenesis (new blood vessel formation), and upregulates growth hormone receptors. It also interacts with the dopaminergic system and has been shown to accelerate tendon-to-bone healing by promoting collagen synthesis.GHK-Cu stimulates collagen and elastin synthesis, promotes glycosaminoglycan production, supports blood vessel growth, and has antioxidant and anti-inflammatory properties. It remodels damaged tissue and activates wound-healing genes.

Research SummaryExtensive preclinical studies demonstrate efficacy in healing tendons, ligaments, muscles, and the GI tract. Animal studies show acceleration of wound healing, protection against NSAID-induced gut damage, and neuroprotective effects. Limited human clinical trials exist.Studies demonstrate increased collagen synthesis, improved skin elasticity, reduced fine lines, and accelerated wound healing. Research shows it can reset gene expression to a healthier state and may have systemic anti-aging effects beyond skin.

Frequently Asked Questions: BPC-157 vs GHK-Cu

What is the difference between BPC-157 and GHK-Cu?

BPC-157 is a healing peptide that a synthetic peptide derived from a protein found in human gastric juice. known for its remarkable tissue healing properties across multiple body systems. GHK-Cu is a skin & hair peptide that a naturally occurring copper-binding peptide found in human plasma, saliva, and urine. widely used in skincare for its wound healing and anti-aging properties. The main differences lie in their mechanisms of action and clinical applications.

Which is better, BPC-157 or GHK-Cu?

Neither is universally "better" - the choice depends on your specific goals. BPC-157 is typically used for healing purposes, while GHK-Cu is used for skin & hair. Always consult with a healthcare provider to determine which may be appropriate for your situation.

Can BPC-157 and GHK-Cu be used together?

Some peptide protocols combine multiple compounds for synergistic effects. However, using BPC-157 and GHK-Cu together should only be considered under medical supervision, as both compounds have their own side effect profiles and potential interactions. Research on their combined use may be limited.
