Get StartedGlutathione is a tripeptide (glutamate, cysteine, glycine) that every cell in your body produces. It is the most abundant intracellular antioxidant and the key molecule behind Phase II liver detoxification. Levels decline with age, stress, and toxin exposure. Subcutaneous delivery bypasses digestive breakdown for far higher bioavailability than oral supplements.
Glutathione may support powerful antioxidant protection against free radicals, liver detoxification of heavy metals and environmental toxins, enhanced immune cell function including NK cell activity, brighter and more even-toned skin, and improved energy by protecting mitochondria. All benefits are based on published research and individual results may vary.
Glutathione is administered as a simple subcutaneous injection. Typical dosing includes injections on a provider-determined schedule. PeRx ships it fully reconstituted and ready to use. Insulin syringes and a step-by-step guide are included.

Your body already makes the most powerful antioxidant on earth. It just needs more of it.
Glutathione is not a supplement trend. It is a tripeptide that every cell in your body produces to neutralize free radicals, detoxify your liver, and keep your immune system running. Your body has been making it since the day you were born.
The problem is that levels decline as you age, and they drop faster when you're stressed, exposed to environmental toxins, or fighting illness. Subcutaneous glutathione bypasses digestive breakdown entirely, delivering it directly where your cells need it most.
Why do people explore Glutathione therapy?
May brighten and even out skin tone by inhibiting melanin production and protecting skin cells from oxidative damage.
May support liver detoxification by binding to toxins and heavy metals, making them water-soluble so your body can flush them out.
May improve energy levels by protecting mitochondria from oxidative damage. Healthier mitochondria means more efficient energy production.
May enhance immune function. Studies show glutathione supplementation increased NK cell activity by over 200% in healthy adults.
May slow cellular aging by neutralizing free radicals before they damage DNA, proteins, and cell membranes. Your cells stay healthier for longer.

Glutathione vs. NAD+
Not sure which one you need? Here's how they compare.
Glutathione
Master antioxidant
| 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 |
| Ideal 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 |
Better Together: Glutathione + NAD+
Glutathione protects your cells from damage. NAD+ powers them with energy and repairs DNA. Together they address both sides of cellular aging: defense and repair.

My skin has never looked this good
“I started glutathione for detox support but the skin results blew me away. By week three, friends were asking what I changed. My complexion is brighter, more even, and I just look healthier overall.”
Jennifer L.

Energy I have not felt in years
“I work long hours and was constantly dragging by 2pm. Two weeks into glutathione and the afternoon crash is gone. I feel like my cells are actually working again. The energy is clean and sustained.”
Mark D.

Real detox, not a trendy cleanse
“I was tired of juice cleanses that do nothing. My provider explained how glutathione actually supports liver detox pathways. Four weeks in and my bloodwork improved. This is the real thing.”

Glutathione Injection
Glutathione is a tripeptide made of three amino acids (glutamate, cysteine, and glycine) that every cell in your body produces naturally. It is the most abundant intracellular antioxidant and the key molecule your liver uses for Phase II detoxification. Levels decline with age, stress, poor diet, and toxin exposure. Subcutaneous injection delivers it directly into your system, bypassing digestive breakdown for far higher bioavailability than pills.
Glutathione is generally very well tolerated, which makes sense considering your body already produces it. The most commonly reported side effects are mild: redness or slight soreness at the injection site. Some people report temporary bloating during the first few days. No serious adverse effects have been documented at standard therapeutic doses.
Glutathione is not recommended if you are pregnant or breastfeeding, currently undergoing chemotherapy (glutathione may interfere with certain agents), have asthma that is poorly controlled, or have an allergy to any component. Always disclose your full medical history during screening.
Most patients notice improved energy and reduced brain fog within 1-2 weeks. Skin brightening and immune improvements typically become noticeable by weeks 4-8. Full antioxidant and detox benefits build over the 8-12 week protocol.
PeRx ships Glutathione fully reconstituted and ready to use. Store refrigerated at 36-46°F (2-8°C). Do not freeze. Keep the vial upright and away from direct light.
Glutathione is not FDA-approved for any specific condition. It is available as a compounded medication prescribed by licensed providers and prepared at FDA-registered 503A pharmacies. It has decades of published research supporting its role as the body's master antioxidant.
No. The entire process is done online. Complete a health screening, a licensed provider reviews your profile remotely, and your medication ships directly to your door via FedEx Overnight.
Every order includes a provider evaluation and prescription, pharmacy-grade Glutathione from an FDA-registered 503A pharmacy, insulin syringes, alcohol swabs, a step-by-step injection guide, and FedEx Overnight shipping.
Yes. Glutathione pairs well with NAD+ (antioxidant defense + cellular energy), GHK-Cu (cellular protection + skin rejuvenation), and Thymosin Alpha-1 (detox + immune resilience). Your provider can advise on combinations.
Oral glutathione has notoriously poor bioavailability because it gets broken down in the stomach before reaching your cells. Subcutaneous injection delivers it directly into your system, bypassing the digestive tract entirely. The result is significantly higher cellular glutathione levels compared to pills or capsules.
