Neutralizes free radicals at the source
Glutathione donates electrons to unstable free radicals before they damage DNA, proteins, and cell membranes — and it regenerates vitamins C and E, so your entire antioxidant system runs better.

About
What is Glutathione?
Glutathione is a tripeptide — glutamate, cysteine, glycine — that every cell in your body makes naturally. It is the most abundant antioxidant inside your cells and the key molecule your liver uses for Phase II detoxification. Levels fall with age, stress, poor diet, and toxin load.
It does three big jobs: it neutralizes free radicals (and regenerates other antioxidants like vitamins C and E, so your whole defense system works better); it binds toxins, heavy metals, and metabolic waste in the liver so they can be flushed; and it protects your mitochondria from the oxidative byproducts they generate. In one clinical study, supplementation raised natural-killer-cell activity by over 200%. PeRx delivers it as a subcutaneous injection — oral glutathione is largely broken down before it reaches your cells, so injection gives far higher bioavailability.
PeRx ships Glutathione fully reconstituted from an FDA-registered 503A pharmacy. No mixing — insulin syringes and a step-by-step guide arrive in the box. It is a subcutaneous injection on a provider-determined schedule.
Why do people explore Glutathione therapy?
Brightens and evens skin tone by inhibiting melanin production and shielding skin cells from the oxidative damage that dulls them.
Binds to toxins and heavy metals and makes them water-soluble, so your liver can flush them out rather than store them.
Protects your mitochondria from oxidative damage, and healthier mitochondria means cleaner, more efficient daily energy production.
Glutathione supplementation raised NK cell activity by over 200% in healthy adults in one clinical study, a serious immune signal boost.
Neutralizes free radicals before they damage DNA, proteins, and cell membranes, so your cells stay healthier and last longer.
Why people explore Glutathione
A clearer path forward.
Powers your liver's detox engine
In Phase II liver detox, glutathione binds toxins, heavy metals, and metabolic waste and makes them water-soluble so your body can flush them. Without enough, that waste builds up.
In a clinical study, supplementation raised natural-killer-cell activity by over 200% in healthy adults.
Guards your mitochondria from the inside
Your mitochondria make energy but also generate oxidative byproducts. Glutathione protects them from the inside out — healthier mitochondria mean cleaner daily energy, slower cellular aging, and better resilience under stress.

The science
How Glutathione works.
Glutathione neutralizes free radicals, regenerates other antioxidants (vitamins C and E), supports Phase II liver detoxification, and modulates immune cell function. It protects mitochondria and DNA from oxidative damage.
01
Signal
Glutathione is given as a subcutaneous injection on a provider-determined schedule — the SubQ route bypasses the gut, where oral glutathione is largely broken down.
02
Cellular response
Glutathione neutralizes free radicals, regenerates other antioxidants (vitamins C and E), supports Phase II liver detoxification, and modulates immune-cell function. It protects mitochondria and DNA from oxidative damage.
03
Outcome
Over the following weeks most people notice improved energy and less brain fog first, with skin looking less dull (weeks 1–2), then steadier energy, brighter and more even skin, and faster recovery (weeks 2–4), then noticeably clearer skin, stronger immune response, and better stress tolerance (weeks 4–12).

Lab tested medications
for quality & potency
Our medication is delivered from a state-licensed pharmacy in our network, right to your door when you need it.
Third-party quality control testing
Compounded in U.S. pharmacies
Lab tested for quality & potency
Our pharmacies perform third-party testing through FDA and DEA registered labs to run quality control checks for every compounded lot. They test four key characteristics associated with quality and safety.
Potency Test
PassedPerformed on every batch to confirm the active ingredient is present at the labeled concentration. Your vial contains exactly what it should.
Sterility Test
PassedTests for the presence of bacteria, fungi, and other microorganisms. Every batch is tested and must meet the requirements of USP 797.1.
Endotoxin Test
PassedScreens for bacterial endotoxins that can cause fever or adverse reactions. Every batch is tested and must not exceed the threshold limits defined in USP 85.
pH Test
PassedAssesses the acid/base balance to ensure minimal irritation upon injection and confirm the solution is within the correct range for subcutaneous administration.
What to expect
Your Glutathione timeline.
- 01
Week 1–2
Foundation
What you may notice: Many people notice improved energy and less brain fog within the first week. Sleep quality may improve. Skin may begin to look less dull.
What’s happening: Your body is restoring baseline glutathione levels. Cells are clearing accumulated oxidative damage and your antioxidant defense system is coming back online.
- 02
Week 2–4
Building momentum
What you may notice: Energy more consistent through the day. Skin starting to look brighter and more even-toned. Recovery from workouts and illness improving.
What’s happening: Glutathione is supporting cellular repair across multiple systems. Your liver detox pathways are running more efficiently and systemic inflammation is decreasing.
- 03
Week 4–8
Full effect
What you may notice: Noticeable skin clarity and glow. Stronger immune response. Better stress tolerance. Most people feel a meaningful difference by this point.
What’s happening: Full antioxidant and detox support is established. Your body has rebuilt its glutathione reserves and is maintaining optimal cellular protection across all tissues.
- 04
Week 8–12+
Sustained protection
What you may notice: Optimal antioxidant defense maintained. Ongoing cellular protection. Skin improvements continue to compound. Most people continue for long-term wellness support.
What’s happening: Your body is operating with robust antioxidant reserves. Cellular aging is slowed and your immune system, liver, and skin all benefit from sustained glutathione levels.
Comparison
Glutathione vs. NAD+
One protects your cells; the other powers them — here's how to choose.
| Glutathione | NAD+ | |
|---|---|---|
| Best for | Detoxification, antioxidant defense, skin health | Cellular energy, DNA repair, cognitive function |
| How it works | Neutralizes free radicals and drives liver detox | Fuels mitochondria and activates sirtuins for DNA repair |
| Scope | Defense — protects cells from damage | Energy — powers cells and repairs DNA |
| Best if you have | High toxin exposure, skin concerns, immune weakness | Low energy, brain fog, age-related decline |
| Can combine? | Yes — pairs well with NAD+ | Yes — pairs well with Glutathione |
