downsides of ghk cu Peptides: What they are, potential benefits, and safety concerns If You Stop GHK-Cu What

PubMed, elechowska, P., et al

Data from the 2021 Nature Aging paper are particularly illuminating on this point

Side Effects & Safety No lethal dose found -- toxicology studies couldn't establish an LD50 (Sikiric et al., 2006) No organ toxicity in chronic dosing No hormonal effects -- doesn't affect testosterone, estrogen, cortisol, or GH Mild nausea -- mostly with oral dosing Brief lightheadedness -- occasionally after injection Injection site redness -- standard for SC peptides Angiogenesis concern -- promotes new blood vessel growth, which raises a theoretical question about existing tumors

Just theoretical potential based on complementary mechanisms and a growing number of biohackers experimenting on themselves

If the test result is low, the answer is yes , which we call a positive test
