The study noted more growth hormone receptor expression and Janus kinase 2 (JAK2) signaling pathway activation under experimental conditions. Tendons have few cells and a poor blood supply, which means they heal slowly, but the research shows that BPC-157 may fundamentally alter the cellular machinery of tenocytes, which can make them more efficient
Mechanism of Action (MOA) Copper Peptide (GHK-Cu) is a naturally occurring tripeptide complexed with copper ions
Winayanuwattikun P, Ketterman AJ
Age-Related Decline In the body, GHK-Cu naturally occurs at concentrations of approximately 200 ng/mL in plasma at age 20, but these levels decline progressively with age to less than 80 ng/mL by age 60 - this age-related decline correlates with decreased tissue repair capacity, skin aging, and impaired regenerative responses, leading to the hypothesis that GHK-Cu decline contributes to aging phenotypes and that restoration of youthful levels through supplementation could have anti-aging benefits
This is where the conversation gets interesting and shifts from a simple question of how much gets into the blood to where it's needed most
