“Six weeks in, she’s back on the trail. I got my dog back.”

The problem
The slowing down happens quietly.
The walk gets shorter. The stairs get a pause. After a good day she pays for it for two. Vet visits add up to €5,000+ and the feeling stays: you'd give anything for more good days.
How it works
Signals, not building blocks.
Most joint supplements supply raw material
Powders dump raw building blocks and hope the body sorts it out. A peptide doesn't hope, it carries a precise instruction to the cells that need it.
Peptides carry a signal
Peptides like BPC-157 are studied for how they interact with specific receptors and tissue-response pathways. A signal, not just an ingredient.
Which is why evidence matters more, not less
So we film every dog and publish the footage. Belief is earned in movement, not in marketing claims.

Four research directions. One complete formula.
What’s inside every KLOW pen
Four research compounds, included together in one pre-filled pen. They are not sold as separate products.
- 1
GHK-Cu · Research focus
Tissue Remodeling & Regenerative Signaling
GHK-Cu is studied for its relationship with tissue remodeling, cellular signaling and regenerative biological processes.
COA tested - 2
TB-500 · Research focus
Cellular Movement & Repair Pathways
TB-500 is explored in research involving cellular movement, actin-related processes and tissue-response pathways.
COA tested - 3
BPC-157 · Research focus
Tissue Response & Recovery Pathways
BPC-157 is studied in preclinical research involving tissue-response, cellular protection and recovery-related biological pathways.
COA tested - 4
KPV · Research focus
Inflammatory Response & Immune Signaling
KPV is a three-amino-acid fragment derived from alpha-melanocyte-stimulating hormone, commonly known as alpha-MSH. Researchers study KPV for its relationship with cellular inflammatory signaling, immune-response pathways and tissue environments.
- Derived from the C-terminal sequence of alpha-MSH
- Studied for its interaction with inflammatory signaling pathways
- Investigated in relation to NF-κB activity
- Explored for its relationship with inflammatory cytokine production
- Studied in laboratory and animal research involving intestinal and tissue environments
Exploring how biological signals may influence the body’s response to stress and irritation.

Options
Peptides vs. everything else.
NSAIDs kill pain faster. Surgery fixes what no molecule can. Peptides sit in a different place, they signal repair, not just mask it.

Timeline
A realistic timeline.
Week 1-2
Settling in
Nothing dramatic. Owners commonly report a slightly easier first step in the morning.
Week 3-4
Earliest reported changes
This is where most owners tell us they notice it, stairs taken without the pause.
Week 5-8
Full cycle completed
The cycle finishes. Owners commonly report longer walks with less payback the next day.
Ongoing
Reassess
Review what changed, then decide whether to repeat the cycle or hold.
Individual responses vary widely. Some dogs show no change at all. That is exactly what the guarantee is for.

What owners are looking for
Start from what you’re trying to change.
The dog who's slowed down
She still wants the walk, she just doesn't ask for it anymore. Mornings are stiff and the sofa wins more often than it used to.
Explore KLOW →
The dog coming back from injury
Post-op, a cruciate, a bad landing. The vet did their part; now it's the slow, fragile part where soft tissue decides how well it heals.
Explore KLOW →
The working or sporting dog
Agility, field work, protection sport. The load is chosen, not accidental, so the wear is constant and the recovery window is never long enough.

The dog you want more years with
Nothing is wrong yet. That's exactly the point, you'd rather act at seven than react at eleven.

Questions
Questions we get asked.
PeppVet KLOW is an all-in-one pre-filled pen containing four research compounds: GHK-Cu, TB-500, BPC-157 and KPV.
Each package contains one pre-filled KLOW pen with a total content of 80 mg. Shipping is free worldwide.
No. KLOW brings all four research compounds together in one pre-filled pen.
KLOW contains GHK-Cu, TB-500, BPC-157 and KPV.
PeppVet KLOW is manufactured in the United Kingdom.
The product is supplied with documented quality-control information and certificate-of-analysis testing. Available documentation can be found in the Lab Reports section.
KPV replaces Epitalon in the updated KLOW formula. KPV is studied for its relationship with cellular inflammatory signaling and immune-response pathways.
Thinner than we'd like, and we say so. The bulk of the published work is laboratory, rodent and equine research, not large controlled canine trials.
Dogs under 12 months, pregnant or nursing dogs, any dog with a current or previous cancer diagnosis, dogs with liver disease or copper-storage-prone breeds (KLOW contains GHK-Cu), and any dog on concurrent medication without veterinary review.
Yes, particularly if she's on other medication. A vet can assess what's relevant to your dog and spot any contraindications before you start.
KLOW is supplied for veterinary research use only. It is not an approved veterinary medicine and we make no claim that it treats or cures any disease.
Sixty days, full refund, no return required and no questions asked. Email us and it's processed, the risk sits with us, not with you.
