  • GHK-Cu as a gel on diabetic foot ulcers closed the wounds by a median of 98.5 percent, on vehicle gel by 60.8 percent.3
  • Glutathione as an infusion did not protect against nerve damage from chemotherapy in a phase 3 trial with 185 cancer patients. In Parkinson's disease the difference from placebo was not significant.45
  • For skin lightening by infusion there is only one small placebo study without a significant difference, taken orally or as a cream glutathione lowered the melanin index in studies. Oral NADH helped 31 percent of people with chronic fatigue, placebo 8 percent.68

What is GGH?

GGH is a premium anti-aging blend combining four synergistic actives in a single vial: GHK (the copper tripeptide), glutathione (the body's master antioxidant), histidine (an essential amino acid with antioxidant function) and NADH (the reduced form of the energy coenzyme).

The idea: each active has a clear anti-aging effect on its own, in combination they complement each other. GHK stimulates collagen, glutathione neutralizes radicals, histidine protects cell membranes, NADH powers the mitochondria.

What the four components do

  • GHK (glycine-histidine-lysine): tripeptide with copper binding. Stimulates collagen synthesis, promotes skin regeneration and wound healing.
  • Glutathione: the body's most important antioxidant. Protects cells from oxidative stress, brightens skin, supports liver detox.
  • Histidine: essential amino acid. Forms histamine in the body, protects red blood cells from oxidative damage, anti-inflammatory.
  • NADH: the electron-rich form of NAD+. Drives the mitochondrial respiratory chain, raises cell energy.

Simplified: more receptors does not automatically mean better, each path also brings its own effects.

How to take it

Subcutaneous injection with an insulin needle, ideally in the abdomen (keep clear of the navel) or the front and inner side of the thigh.

  • Swirl or shake before each injection, both are fine.
  • Draw the desired amount with a U-100 insulin syringe.
  • 2-3x per week is enough thanks to cumulative effects across multiple mechanisms.

Topical use is theoretically possible but bioavailability is much worse than subcutaneous.

What GGH is researched for

  • Skin structure: the GHK portion stimulates collagen and elastin in the dermis.
  • Glow and brightening: glutathione is known for its skin-tone brightening effect.
  • Oxidative stress: the antioxidant components (glutathione, histidine) reduce systemic stress.
  • Cell energy: NADH improves mitochondrial function - some users report less fatigue.

Components and findings

Tap a point or a card. Colour = component (GSH = glutathione, His = histidine), data from studies on the single compound.

  1. Skin and wounds

    GHK-Cu gel: foot ulcers closed by a median of 98.5%3

  2. Cells and liver

    Glutathione is the most abundant small thiol in the cell and protects against oxidative damage2

    GSH
  3. Brain (Parkinson's)

    Intravenous glutathione: no significant difference from placebo5

    GSH
  4. Fatigue

    Oral NADH: 31% responded, placebo 8%8

    NADH

What the research shows

The single actives each have solid data sets:

  • Pickart et al. 2015: comprehensive review on the molecular action of GHK-Cu on skin regeneration and anti-aging.
  • Forman et al. 2009: review of glutathione as the cell's most abundant low-molecular-weight thiol, protecting against oxidative damage and keeping redox balance.

Studies on the exact GGH blend don't exist - the combination is based on the logic of the single actions.

Study results

What the trials measured

Interactive: switch tabs, tap points, show or hide arms. Arms are named relative to each other, no dosing advice.

Wound closure in diabetic foot ulcers3

Median closed wound area, randomised trial with gel on the wound

All ulcers on the sole3
Placebo or vehicle gel +60.8%
GHK-Cu gel on the wound +98.5%
Large ulcers (over 100 mm²)3
Placebo or vehicle gel -10.3%
GHK-Cu gel on the wound +89.2%

Minus = the ulcer grew. Ulcer infections: 7 percent with GHK-Cu gel against 34 percent with vehicle gel. Gel on the skin, not an injection and not the blend.

Skin lightening with intravenous glutathione6

Share with lightening, the only placebo study according to a systematic review (16 people each)

Lightening6
Placebo or vehicle gel 18.7%
Intravenous glutathione 37.5%

Difference not significant (p = 0.054). The review considers infusions not indicated because of missing efficacy and side effects. In a phase 3 trial with 185 cancer patients glutathione infusions did not protect against nerve damage from chemotherapy.

NADH in chronic fatigue8

Share with good response, 26 people, placebo and NADH one after the other (crossover)

Good response8
Placebo or vehicle gel 8%
Oral NADH 31%

8 of 26 on NADH, 2 of 26 on placebo. Oral NADH, small pilot study without severe side effects.

Research status

Where the research stands

There is no study on the blend itself. Shown are registered trials with glutathione as an infusion; for GHK and NADH the registry only lists trials with gels, serums or capsules. As of 25 Oct 2026. 11

  2. Phase 1 no registered trial
  3. Phase 2 no registered trial

Bar: start to primary endpoint (planned for running trials). Green = completed, blue = progress until 25 Oct 2026.

Side effects

  • Skin redness: normal at the injection site for some hours.
  • Mild odor: typical for glutathione-containing solutions (sulfur note).
  • Very rare allergic reaction: start low, observe.

Storage

Refrigerate, protect from light. NADH is particularly light- and temperature-sensitive. Use within 4-6 weeks after opening.

FAQ

Common questions about GGH (GHK + Glutathione + Histidine + NADH)

Short answers, each backed by the sources below.

Are there studies on GGH?

No. There is no study on the ready-made blend, neither on ClinicalTrials.gov nor in PubMed (as of 25 October 2026). Only single components have been studied, mostly in another form: GHK as a gel, glutathione as an infusion, cream or capsule, NADH as a capsule.91011

What does research show on GHK?

GHK binds copper and acts on many skin regeneration pathways in cell and animal studies. In a randomised trial GHK-Cu gel closed diabetic foot ulcers by a median of 98.5 percent, vehicle gel by 60.8 percent; in large ulcers 89.2 against minus 10.3 percent. Infections occurred in 7 instead of 34 percent with the gel.13

Does glutathione as an injection lighten the skin?

That is not proven. Taken orally or as a cream glutathione lowered the melanin index in several randomised trials. For intravenous glutathione a systematic review found only one placebo study: 37.5 against 18.7 percent with lightening, not significant. The review therefore and because of side effects considers infusions not indicated, the Philippine drug authority issued a public warning. There is no study on use under the skin.67

What is known about glutathione infusions?

In a phase 3 trial with 185 cancer patients glutathione before chemotherapy did not protect against nerve damage, with weekly paclitaxel an acute pain syndrome was even milder on placebo. In a small Parkinson's trial with 21 people glutathione was well tolerated but mobility did not improve significantly more than on placebo.45

What does NADH do?

NADH is the energy-rich form of NAD+ and supplies electrons to the respiratory chain of the mitochondria. In a small study with 26 people with chronic fatigue 8 responded to NADH and 2 to placebo. Oral NADH was tested, not an injection.8

Which side effects have been described?

There are no data on the blend. Intravenous glutathione was well tolerated in the Parkinson's trial, nobody stopped because of side effects. Oral NADH showed no severe side effects. For skin lightening by infusion reviews report side effects that led to an official warning.587
