What users report
A clearer, more even complexion
Reserves that rise
Better recovery from exercise and nights out
The antioxidant every cell already makes, sought for a radiant complexion and for handling exercise, nights out and stress better.
A clearer, more even complexion
It slows tyrosinase, the enzyme that makes melanin, and a placebo-controlled trial measured a lighter complexion on sun-exposed areas (Arjinpathana, 2012).
Reserves that rise
In a placebo-controlled trial in 54 adults, intake by mouth raised its reserves by 30 to 35% in the blood and up to 260% in some cells (Richie, 2015).
Better recovery from exercise and nights out
In the body, it neutralizes free radicals and then regenerates, and the liver uses it to clear alcohol and pollutants.
Laboratory research

People choose it for a radiant complexion and antioxidant defence: its levels rise in the blood and in the cells, while oxidative stress goes down.
What it is: A tripeptide that every cell makes, the body's most abundant antioxidant, injected to bypass the gut, where it is largely broken down when taken by mouth.
Laboratory research
In a placebo-controlled trial, glutathione intake raised its stores by up to 260% in the cells measured (European Journal of Nutrition, 2015).
This tripeptide is the body's most abundant antioxidant: every cell makes it. Taken by mouth, it is largely broken down in the gut; injection skips that step.
Why people choose it:
- Skin tone: it slows tyrosinase, the enzyme that makes melanin; a placebo-controlled trial measured a lighter skin tone on sun-exposed areas (2012).
- Defences: in the 2015 trial, the activity of NK immune cells increased.
- Liver: the liver uses it to clear alcohol, medications and pollutants; its precursor is the hospital antidote for acetaminophen overdose.
It is the only product in our catalogue studied for slowing tyrosinase.

What to combine it with?
Pick one to three products: the text follows your combination.
Two cycles that recharge each other
What each one brings
- NAD+ : Through the NADPH derived from it, it regenerates glutathione once it has been used.
- Glutathione : The body's most abundant antioxidant, whose levels rise in the blood and in the cells.
Why together
NAD+ is needed to put oxidized glutathione back into service: the two cycles support each other. One supplies energy and recharging power, the other the antioxidant defence that benefits from it.
What adds up
- An antioxidant defence that renews itself instead of running down.
- The energy and clarity reported with NAD+, the radiant complexion people look for with glutathione.
In practice
Two pens, each on the protocol shown on its own page, within the same week.
When will I feel the effects?
Weeks 1 to 2
Getting started
The dose rises in two-week steps. Noticing nothing at the start is perfectly normal.
Weeks 3 to 4
Your complexion, in photos
Photograph your complexion in the same light: the first changes are often noticed from the fourth week on.
Weeks 5 to 11
A more even complexion
According to user reports, a more even complexion takes shape between the fourth and the twelfth week of consistency.
Week 12 and up
Time to take stock
The twelve-week cycle ends and a four-week break follows: compare with your starting photo.
These timings vary from one person to the next. This timeline is a guide, not a promise.

How to use
The box
- Ready in one step: the included water syringe is already measured for this pen.
- In the box: the pen, its pre-measured water syringe, 12 needle tips (a new one for each injection) and the alcohol swabs.
- The Peptiva system: powder sealed without air or light, intact down to the last dose. Sealed until you: the box is shrink-wrapped at Peptiva, you are the first person to open it. Pen or vial: the difference
- Shipped from Quebec by Xpresspost, 1 to 2 business days in Quebec and Ontario*, with tracking. Replacement if your package is lost.
- Analyzed by Sidechain, independent laboratory · certificate published when the batch arrives.
- Pen with a defective mechanism: our team assesses it, and replaces it at no charge if the defect is confirmed. See the details.
Shipping
- More items, more value: shipping ($20.00) is on us from 2 items (anywhere in Canada). This product is sold in packs of 2 pens or more, so shipping is always on us; its price already carries its own scale and stays outside the quantity discounts. Your member discount applies.
- Read the full educational profile : description and how to use it, in the Centre.
Storage
Good for 6 weeks after reconstitution, if it has been kept properly: in the fridge, away from light, with an alcohol swab on the tip before each use. Past that, we do not recommend using it, even if some is left; if the liquid turns cloudy or changes colour, do not use it, even before.
