For this dog
Healthy aging doesn't happen on its own.
- A little less bounce on the stairs.
- Longer naps, shorter games.
- A step slower than they were at three.
Dogs age far faster than we do. Cellular energy output declines, oxidative load increases, and lean mass slowly drifts. The things you think of as "just getting older" have mechanisms, and mechanisms can be supported. Longevity is the proactive formula: daily cellular support for the dog who still seems young, and for keeping it that way as long as possible.
Not for emergencies. For the long run.
The ingredients in Longevity support the cellular machinery healthy aging depends on.
What's in it
Every ingredient listed.
Every amount disclosed.
Every active below is in the formula, with the amount per daily serving. Nothing here that is not on the label.
-
Primary active
Alpha-lipoic acid (ALA)
[amount] mg
A mitochondrial antioxidant that helps regenerate other antioxidants, vitamins C and E included, and supports cellular energy metabolism. It helps manage the oxidative stress that builds with age.
-
Primary active
L-Carnitine
[amount] mg
An amino acid derivative that shuttles fatty acids into mitochondria for energy production. In aging dogs, it supports the cellular fuel economy behind muscle and everyday energy.
-
[Co-nutrient 3, e.g. Coenzyme Q10]
[amount] mg

How it works
Aging is cellular. The formula supports it there.
The biology of aging in dogs, like in humans, is largely a mitochondrial story. As dogs age, mitochondrial function declines: less efficient energy production, more oxidative byproducts, slower cellular repair.
Longevity pairs ALA and L-carnitine to support that machinery. Not by reversing age, but by maintaining the cellular conditions healthy aging runs on.
-
The load
Manages oxidative stress
Alpha-lipoic acid helps manage the oxidative load that builds up in aging cells.
-
The fuel
Supports cellular energy
L-carnitine supports the mitochondrial fuel pathway that efficient energy production depends on.
-
The delivery
Starts on the tongue
Delivered as a cold-processed tincture, the actives bypass heat degradation. Uptake begins on the tongue, before digestion starts.
Why a tincture, not a chew
| Feature | Typical senior multivitamin | Longevity |
|---|---|---|
| Focus | Broad nutritional gaps | Mitochondrial energy and oxidative stress |
| Actives | Low-dose vitamin mix | ALA and L-carnitine plus co-nutrients |
| Processing | Heat-pressed tablet | Cold-processed |
| Absorption | After digestion | Starts on the tongue |
Consistency matters
Give it 4 to 6 weeks of daily use. Cellular support is cumulative and builds with consistent dosing.
The ritual
One dropper. On the tongue.
Every day.
Thirty seconds a day, straight from the fridge door. No pill pockets, no crushed tablets hidden in dinner, no negotiation.
-
Keep it cold
PupPepz lives in your refrigerator, next to the things you keep fresh on purpose. Cold storage protects peptide integrity for the full 30-day supply.
-
Draw one dropper
1 mL daily for dogs up to 50 lb, 2 mL for 50 lb and over. The graduated dropper is precise to the line, every time.
-
Drop on the tongue
Mild, savory-neutral taste dogs accept readily. Absorption starts before the bowl is even down.
FAQ
Questions, answered.
Everything owners ask us before their first bottle.
What are peptides, and are they safe for dogs?
Peptides are short chains of amino acids, the building blocks of protein. Your dog's body already makes and uses them. PupPepz provides peptide fractions and co-nutrients as a supplement to your dog's normal diet. Always check with your vet before starting any supplement, especially if your dog has a medical condition or takes medication.
How much do I give my dog?
1 mL daily for dogs up to 50 lb, 2 mL daily for dogs over 50 lb. Directly on the tongue or over food.
Why does it need to be refrigerated?
Cold storage protects peptide integrity. It's the same reason the tincture is cold-processed and cold-shipped.
Can I stack this with Motion or Shield?
Yes. All three formulas are designed to be combined. Longevity pairs especially well with Motion for older dogs with both joint and energy concerns.
What can I actually expect to see?
Changes are cumulative and more subtle than a joint or anti-itch product. Owners look for sustained energy, coat quality, and engagement relative to their dog's age. Give it 4 to 6 weeks of daily use. Every dog is different.
When should a dog start Longevity?
Many owners start between ages 4 and 6, before visible aging begins. Cellular support works as maintenance, not rescue. It remains meaningful for older dogs as well.
How is Longevity different from a multivitamin?
A multivitamin covers general nutritional gaps. Longevity focuses on mitochondrial function and oxidative stress, the cellular mechanisms most closely tied to aging.
Can I pause or cancel my subscription?
Anytime, from your account. No calls, no forms.
