What is the half-life of GHK-Cu?

GHK-Cu has a half-life of Unknown, which is why it's typically administered As needed for optimal therapeutic effect.

How do I reconstitute GHK-Cu?

Add bacteriostatic water to the peptide vial slowly down the side. Typical reconstitution uses 2-3ml of water for a 5mg vial. Gently swirl, do not shake.

Research Summary

Preclinical

Broad Institute Connectivity Map data revealed that GHK-Cu modulates expression of 32% of human genes, including clusters associated with circadian rhythm, neuronal function, and inflammatory regulation. While not traditionally classified as a sleep peptide, its broad gene-regulatory profile supports systemic conditions conducive to restorative sleep. Dr. Loren Pickart's research demonstrated anti-inflammatory and neuroprotective effects that are mechanistically relevant to sleep quality. Clinical evidence for direct sleep improvement is indirect, based on gene expression and anti-inflammatory data rather than sleep-specific trials.
