Evidence Limitations and Unanswered Questions The main evidence limitations for GHK-Cu are uneven human data, formulation differences, limited injectable safety information, small topical skin studies, indirect hair evidence, and uncertain long-term outcomes [2], [6], [7], [8]
They are not permanent and need maintenance to sustain
However, while they are recognized for their skin-lightening and brightening effects, the outcomes can vary and are not always predictable
There are two different forms of glutathione
Example combined protocol: Morning: CJC-1295 (100mcg) + Ipamorelin (100mcg) Evening: GHK-CU (1-2mg) Separating administration times prevents potential interactions at the injection site and allows each peptide to work through its distinct pathways without interference
