In interim data presented this spring, investigators found that patients experiencing medication-driven weight loss showed a significant reduction in adipose-derived stem cells cells involved in tissue regeneration and structural support.[2] That may help explain why some people notice: hollow cheeks and temples, crepey or loose skin, increased dryness, more visible wrinkles, sagging around the jawline, and skin that suddenly looks tired or deflated
GHK-Cu is not a foreign chemical
The mechanism is mechanistically additive: GHRH directly stimulates somatotrophs through a separate receptor, while GHRPs suppress somatostatin and prime GHSR-1a simultaneously
However, the quantitative effects of carnitine supplementation on body weight in patients with PCOS and optimal treatment scheme are still unknown
These multiple cellular pathways explain why GHK-Cu attracts attention, but they also make it harder to reduce the peptide to one simple mechanism of action
