Without human safety or efficacy data, any calculated dose should be viewed as a rough starting point, not a prescription

The human skin-benefit evidence improved firmness, elasticity, and reduced fine lines comes almost entirely from topical creams and serums

GHK-Cu is a naturally occurring copper complex of the tripeptide glycyl-L-histidyl-L-lysine

Now, many of these inducers will only reduce ethinyl estradiol/progesterone by 10%20%, but the risk is nontrivial and the science inexact, so double protection is a wise strategy here

Any potential synergy remains theoretical and unproven in human studies
