Dosing matters because GHK-CU operates through gene expression modulation
These observations in RNA-seq data were further validated by qRT-PCR for selected Wnt/-catenin pathway-related genes including AMER3 , NRARP , CCND1 , LRG1 , and LEF1 in hDP cells exposed with various doses of NTAPP (3.6 kV, 4.2 kV, and 5.0 kV) (Fig

No this is normal, and your peptides are fine
The authors reported a 55.8% reduction in facial wrinkle volume and a 32.8% reduction in wrinkle depth compared with control serum, alongside in vitro evidence that GHK-Cu increased both collagen and elastin production in human dermal fibroblasts at concentrations as low as 0.01 nM [4]
Impaired function can lead to MTHFR mutation symptoms related to hormone imbalance, such as: Fibrocystic breasts and ovarian cysts Mood swings and PMS Irregular or heavy periods Endometriosis Uterine fibroids 4
