Full Glow Blend profileGHK-Cu
GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, a molecule Pickart and Thaler first pulled out of human plasma in 1973. The free peptide (GHK, C14H24N6O4) weighs about 340.4 Da; bind it 1:1…

| Attribute | Glow Blend | GHK-Cu |
|---|---|---|
| Category | Recovery | Skin, Hair & Aesthetics |
| Research Stage | Preclinical | Approved/marketed as a topical cosmetic ingredient (Copper tripeptide-1) with supporting small human studies. Injectable use is preclinical/off-label, research-use-only, with no human clinical trials. |
| Mechanism of Action | Glow Blend is a fixed combination of three research peptides, so its proposed effects are simply the sum of what each component does on its own - there is no unique "blend" mechanism, and no pharmacology study has ever been run on the three together. Each part… | GHK-Cu works mostly as a copper shuttle and a signaling peptide. It binds Cu(II) with high affinity (log K around 16.4, close to albumin's 16.2) and can supply or regulate copper for copper-dependent enzymes like SOD1, lysyl oxidase, cytochrome c oxidase, and… |
| Half-Life | Varies by component - the blend has no single half-life. BPC-157 and the TB-500 (thymosin beta-4) fragment are small peptides cleared over hours; GHK-Cu is a short-lived tripeptide-copper complex. Community dosing frequency is driven by empirical practice, not by measured pharmacokinetics of the blend. | ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study) |
| Typical Dose Range | Blend - stated per component: GHK-Cu 1000-2000 mcg/day; BPC-157 250-500 mcg/dose; TB-500 2000-2500 mcg/dose. No validated dose exists for the combination (Research Use Only). | 200-500 mcg SC daily (community/RUO; no clinically established injectable dose) |
| Dosing Frequency | GHK-Cu once daily; BPC-157 once to twice daily; TB-500 twice weekly during the loading phase, then every 1-2 weeks for maintenance. | Once daily subcutaneous; some run 5 days on / 2 days off. Topical: 1-2x daily to cleansed skin. |
| Administration | — | Subcutaneous, Topical |
| Side Effects | Most reported effects are local: injection-site redness, swelling, itching, bruising or transient pain, plus mild skin sensitivity. GHK-Cu injections can sting, and with prolonged high-dose systemic use there is a theoretical concern for copper accumulation.… | Topical GHK-Cu is generally well tolerated; higher-concentration formulations (4-5%) raise the odds of irritation, redness, or stinging. Injectable use has no safety data from controlled trials; the main theoretical concern is copper accumulation with repeated… |
| Molecular Weight | — | Free peptide (GHK): 340.38 Da (C14H24N6O4). Copper complex (GHK-Cu): 401.9 Da (C14H22CuN6O4, neutral 1:1 Cu(II) complex). |

Which has the longer half-life, Glow Blend or GHK-Cu?
Glow Blend has a half-life of Varies by component - the blend has no single half-life. BPC-157 and the TB-500 (thymosin beta-4) fragment are small peptides cleared over hours; GHK-Cu is a short-lived tripeptide-copper complex. Community dosing frequency is driven by empirical practice, not by measured pharmacokinetics of the blend.. GHK-Cu has a half-life of ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study). Longer half-lives generally mean less frequent dosing but slower on/off kinetics.
