Naturally derived peptides

Peptides work at the cellular level

Peptides are short-chain amino acids that signal to cells. Research suggests they may support cellular communication, tissue maintenance, and natural biological processes.

Cellular Healing

Peptides signal directly to cells to activate natural repair pathways — promoting tissue regeneration from the inside out rather than masking symptoms.

Skin & Coat Wellness

GHK-Cu has been studied for its role in collagen synthesis and skin barrier biology — research suggests it may support healthy skin and coat appearance.

Recovery & Gut Health

BPC-157 has been studied for its role in supporting soft tissue and GI tract integrity at the cellular level — research suggests it may support recovery, tissue maintenance, and digestive wellness.

Reduce Inflammation

KPV is a naturally derived tripeptide studied for its role in the NF-κB inflammatory pathway — research suggests it may support a healthy inflammatory response.

Overall Vitality

Peptide formulas may support overall cellular wellness — including energy, mobility, and coat appearance — as part of a balanced wellness routine.

What we offer

Three protocols. One platform.

From daily maintenance to advanced recovery — every protocol is designed for your pet's specific condition. Joint pain, allergies, gut issues, post-surgery recovery.

Pet owner stories

They're bounding again.

S

Max — 7yr Golden Retriever

"I wanted something to support Max's wellness alongside conventional care. Having the vet review his profile and the protocol shipped to my door has been a great experience. He's doing well."

M
Marcus T., Miami
Luna — 5yr Labrador

"I appreciated that a vet actually reviewed Luna's profile before anything shipped. It feels different from buying a generic supplement online. She's doing well on the protocol and we're happy."

J
Jennifer M., Phoenix
Bella — 11yr Labrador

"Bella is 11 and we wanted to give her something to support her overall wellness as a senior. The DVM review process gave me peace of mind. She's been on the protocol for a couple of months and we're glad we tried it."

Common questions

Everything you need to know

Which states do you serve?
We currently serve California. Additional states coming soon.
How long until I see results?
Results vary by individual pet, the wellness focus, and consistency of use. Some pet owners notice changes within a few weeks; others find peptide support works gradually as part of an overall wellness routine. Your DVM will discuss realistic expectations based on your pet's profile.
Can I cancel anytime?
Yes. No long-term commitments. Cancel anytime with no penalty. No commitment required to start.
Do you offer protocols for cats too?
Yes. Cats can be candidates for peptide wellness support. Our Tier 1 Coat & Wellness and Tier 2 Allergy & Skin Support are available for both dogs and cats. The Tier 3 Recovery & Digestive Support Protocol is also available — every submission is reviewed by a licensed DVM to determine the right fit for your individual pet.
Can peptides help with my dog's allergies?
KPV is a naturally derived tripeptide that has been studied for its role in supporting a healthy inflammatory response. Whether it's an appropriate fit for your individual pet depends on a full picture of their health and any current medications, which is what the DVM review is for. We always recommend working alongside your conventional vet for any ongoing condition.
How is Companion Peptide different from a generic supplement?
Two things. First, every order is reviewed by a licensed integrative DVM before anything ships — so a peptide that isn't an appropriate fit for your pet (because of a medication, condition, or other factor) doesn't get sent. Second, the formulas are naturally derived peptides studied in the research literature. We're not a replacement for your conventional veterinarian — we're a complementary wellness option with DVM oversight built into every order.
Is KPV well-tolerated in dogs?
KPV is a naturally derived tripeptide. As with any new supplement, individual pets can respond differently — mild GI upset is the most commonly reported adjustment effect when first introduced. Stop use and contact your vet if you notice vomiting, lethargy, facial swelling, or breathing difficulty. Every Companion Peptide order is reviewed by a licensed integrative DVM before shipping to assess fit for your individual pet.
