For DNA repair genes, GHK was primarily stimulatory (47 genes up, 5 genes down), with particularly strong effects on genes like XRCC5 (369% increase) and BRCA2 (189% increase)both critical for maintaining genomic stability
Also in older adults with MCI, higher levels of GSH in ACC were found to be related to lower set shifting and response inhibition, and higher levels of GSH in PCC were related to lower verbal retention (Duffy et al., 2014)
What are the negative side effects of GHK-Cu
New delivery platforms that are optimized for large DNAs, such as synthetic minichromosomes or nanoparticle-based systems, could overcome this barrier
CJC-1295 is a GHRH analog (it tells the pituitary to make GH), while ipamorelin is a growth-hormone secretagogue (it triggers the release of stored GH)
