What GHK is
GHK is gly-his-lys tripeptide, non-copper form. wound and skin research. It sits within cellular-longevity research (mitochondria, connective tissue). Pepture keeps GHK in the library as a tracking target only, the app records what you enter but makes no recommendation about whether the compound is appropriate for you. That decision belongs with a licensed clinician.
Published pharmacokinetic data places the half-life of GHK at roughly 2 hours, and doses recorded in the community cluster around the 1 mg to 3 mg range. Individual protocols vary widely. Jurisdictional status (FDA-approved, prescription, or research only) depends on the specific formulation and country.
How people track GHK
In Pepture, GHK is typically logged alongside subjective energy, sleep depth, optional inflammatory biomarkers, so cycle impact can be reviewed at the end of a block rather than by memory. The app captures dose, site, reconstitution ratio, cycle day, and any subjective rating you choose to add.
If you are considering GHK but have not started, or if you have started and want a second opinion, speak with a licensed clinician before changing any dose or cycle pattern.
