GHK vs Adipotide
Side-by-side comparison of key properties, dosing, and research.
- Summary
- GHK is the natural tripeptide (Gly-His-Lys) released from human albumin that activates tissue remodeling, collagen synthesis, and anti-aging gene expression. The copper-free form is the biological signaling molecule; it chelates copper in tissue to form GHK-Cu but also has independent biological activity.
- Adipotide (FTPP) is a chimeric proapoptotic peptide that selectively targets and destroys blood vessels feeding white adipose tissue. It binds prohibitin on the vasculature of fat tissue, delivering a proapoptotic sequence that induces cell death in fat-specific blood vessels, causing targeted fat tissue regression.
- Half-Life
- Extremely short as free peptide; tissue binding extends local effects
- Estimated 2-4 hours
- Admin Route
- SubQ, Topical, Oral
- Subcutaneous, Intravenous (research)

- Antioxidant and anti-inflammatory
- Wound healing and skin barrier repair
- Improves skin laxity, texture, and radiance
- Neuroprotective (stimulates NGF, BDNF)
- Anti-fibrotic in liver and lung models
- Targeted reduction of white adipose tissue
- Promotes fat vasculature apoptosis without systemic toxicity
- Demonstrated significant fat loss in primate studies
