ghk-cu negative feedback loops Copper toxicity and deficiency: the vicious cycle at the core of protein aggregation in ALS BPC-157, TB-500, and GHK-Cu: Separating

they are research observations in laboratory models

Receptor fluid was collected over 48 h in 4 h intervals

Studies examining full-thickness skin wounds in rats have documented 30-50% increases in wound bed capillary density following GHK-Cu treatment, correlating with 25-40% reductions in time to complete re-epithelialization

Code availability Data reduction was carried out using the publicly available spaceKLIP package ( which also uses functions from the jwst pipeline ( the pyKLIP Python package ( and the webbpsf_ext package ( Orbit fitting was carried out using the publicly available orvara package ( We used various functions from astropy, pandas, matplotlib and seaborn in the analysis and to create figures
