See how research connects peptides to biological targets, signaling pathways, and biological processes.
This tool shows, for each peptide, which biological target the available research points to, how directly that relationship is supported, and how it connects to broader signaling pathways and biological processes. It describes what research suggests about biological mechanisms -- not proven health or treatment outcomes, and not medical advice. See each peptide's full research profile for complete detail, citations, and safety information.

Understanding mechanism evidence
This tool describes research into biological targets, signaling pathways, and biological processes -- not proven health or treatment outcomes, and not medical advice. Relationship-support and evidence-context labels describe the type and directness of research available, not proof of safety or effectiveness.

GHK-Cu
1 mechanism relationship · Directly supported · Preclinical research
GHK-Cu → PRDX6 — Directly supportedIn a 2024 preclinical silicosis/macrophage study, GHK-Cu directly interacted with PRDX6 in tagged-compound physical-interaction assays, with PRDX6 loss-of-function supporting functional relevance; this does not establish a covalent interaction or a universal GHK-Cu mechanism.
Evidence context
Preclinical research
Evidence is preclinical only, drawn from a single 2024 silicosis/macrophage mechanistic study (PMID 38879894); no independent replication of the GHK-Cu/PRDX6 interaction has been found. All reported physical-binding experiments (target-capture, pulldown, immunoprecipitation, purified-protein, and SPR-based assays) used biotinylated/tagged GHK-Cu, and no native/unmodified-GHK-Cu tag-independent binding confirmation was identified in the accessible source text. A numeric SPR Kd is intentionally omitted from this record because the published exponent (rendered inconsistently across the article text and secondary summaries) could not be independently verified. No covalent or irreversible binding is claimed -- the authors' own Thr177 binding-site proposal is docking-predicted/computationally proposed only, not experimentally mapped. PRDX6 silencing in RAW264.7 macrophages attenuated GHK-Cu-associated antioxidant and mitochondrial-protective effects, supporting functional relevance, but this functional evidence does not remove the tagged-compound limitation on the physical-binding assays above. The PRDX6 mechanism was demonstrated specifically in silicosis/macrophage oxidative-stress systems and is not established as the universal explanation for GHK-Cu's broader reported collagen-synthesis, wound-healing, skin, or angiogenic effects. GHK-Cu's separately reported MMP-2 expression-modulation evidence (PMID 11045606) remains a distinct, deferred candidate relationship and is not part of this record.
