The GLOW Protocol for dogs
Also searched as: GLOW stack, GHK-Cu BPC-157 TB-500
The short answer
GHK-Cu added to BPC-157 and TB-500 — investigated where skin, coat, and wound healing are part of the picture alongside soft tissue repair.
What it is and why these compounds
GLOW adds GHK-Cu to the Wolverine pairing. The reasoning is coverage: BPC-157 and TB-500 are investigated for deeper soft tissue, while GHK-Cu has the most relevant research in skin and open wounds — including the one veterinary surgical study on topical application to ischaemic canine wounds. It is most often discussed for post-surgical cases where both the incision and the underlying repair matter, or where coat quality is a secondary concern. GHK-Cu can be applied topically, which means the added burden over the Wolverine protocol is often not an extra injection at all.
Compounds in this protocol
A copper-binding tripeptide with a published canine wound-healing study.
The only peptide on this site with published canine pharmacokinetic data.
The most established compound in veterinary research, with equine work dating to the early 2000s.
Before starting
These are the decisions that determine whether this protocol is appropriate at all.
⚠ Read first
Bedlington Terriers and certain Labrador lines carry inherited copper storage disease. For these dogs the injectable GHK-Cu route should not be used, and topical is the only route worth considering.
Caution
Any dog with hepatic disease should avoid injectable GHK-Cu regardless of breed.
Caution
TB-500 remains contraindicated with active or suspected cancer.
Caution
Three compounds at once makes attributing an adverse effect close to impossible. Introducing them in sequence is the more cautious approach.
Example timeline
A representative schedule drawn from the published literature, showing what is monitored and when. Any actual protocol should be set by the veterinarian managing the case.
- 1Days 1–7Initiation
What owners observe
Apply topical GHK-Cu to the wound or incision twice daily. Begin the injectable components as in the Wolverine protocol. Watch for irritation at topical sites.
Clinical monitoring
Baseline CBC, chemistry, and liver values — the last specifically because of copper handling. Confirm cancer screening for TB-500.
- 2Weeks 2–4Active remodelling
What owners observe
Wound closure visibly accelerating, with coat quality often improving around treated areas. Mobility gains from the injectable components typically become apparent in the same window.
Clinical monitoring
Reassess the wound bed. TB-500 to maintenance at week 3–4. Recheck liver values if injectable GHK-Cu is being used rather than topical.
- 3Weeks 4–8Taper
What owners observe
Discontinue injectables in sequence rather than all at once. Topical GHK-Cu is often continued for chronic dermatologic conditions.
Clinical monitoring
Discontinue injectable GHK-Cu by week 8 at the latest. Recheck liver values if the injectable route was used beyond four weeks.

Common questions
What is the GLOW Protocol for dogs?+
GHK-Cu added to BPC-157 and TB-500 — investigated where skin, coat, and wound healing are part of the picture alongside soft tissue repair. It combines GHK-Cu, BPC-157, TB-500.
Is the GLOW Protocol safe for dogs?+
Bedlington Terriers and certain Labrador lines carry inherited copper storage disease. For these dogs the injectable GHK-Cu route should not be used, and topical is the only route worth considering. Any dog with hepatic disease should avoid injectable GHK-Cu regardless of breed. TB-500 remains contraindicated with active or suspected cancer. Three compounds at once makes attributing an adverse effect close to impossible. Introducing them in sequence is the more cautious approach.
How long does the GLOW Protocol run?+
The example timeline runs from days 1–7 through weeks 4–8. Actual duration should be set by the veterinarian managing the case and adjusted on response.

Where to source research peptides
Compound quality is the variable most owners underestimate. Purity, accurate peptide content, and correct labelling determine whether any published dosing figure means anything at all. Pet & Peps Research publishes third-party testing on the compounds covered in this guide and supports this site.
