Companion satellite-cell cultures, prepared at the same time, were immunostained at 30-h post-plating with D3 anti-desmin mAb and DAB (a chromogenic HRP-substrate that forms an insoluble brown reaction product) to determine the percentage of myogenic cells present 18 ,19 cultures with less than 95% DAB-positive cells (namely, less than 95% desmin-positive myogenic purity) were not used for experiments just to ensure the reliability of data specific to myogenic cells in the employed primary cell culture systems

Consistency is more important than taking a high dose sporadically.

Another study explored the potential interaction between GHK-Cu and hyaluronic acid (HA) on collagen synthesis, particularly focusing on their potential collaborative actions in dermal fibroblasts and an ex-vivo skin model
