GHK-Cus anti-inflammatory mechanism actually partially mitigates the hyperpigmentation risk compared to microneedling without the peptide, but that benefit requires conservative technique to realize
Its a positive feedback loop: better sleep enables better recovery, and better recovery enables better sleep
Some synthetic peptides (made in a laboratory) are very useful as drugs for specific health problems (for example, insulin for treating diabetes or semaglutide for helping with weight loss)
It also triggers angiogenesis by upregulating VEGF, flooding follicles with oxygen and nutrients for accelerated keratinocyte proliferation
GH has also been used experimentally to treat multiple sclerosis, to enhance weight loss in obesity, as well as in fibromyalgia, heart failure, Crohn's disease and ulcerative colitis, and burns
