Vet-supervised peptide wellness, built for the way pet families actually want it.
Companion Peptide is a small, founder-led wellness brand focused on bringing licensed veterinary review into a category that's grown up without it.
What we do
We work with licensed integrative veterinarians to review every protocol before it ships. Customers tell us about their pet — age, weight, conditions, current medications — and a DVM reviews the submission, designs an appropriate protocol or declines the order if it isn't a fit. Only then does product leave our facility.
It's a slower, more intentional model than the typical online peptide store. That's the point.
Why this exists
The pet peptide space today has a structural problem. The science behind peptides like BPC-157, KPV, and GHK-Cu is genuinely interesting, with a growing preclinical research base. But most of the brands selling these compounds to pet owners do so with no clinical screening, no veterinary review, and disclaimers that effectively tell customers, "ask your vet" — knowing full well that most general-practice vets aren't familiar with peptide therapy.
That gap creates two problems. Pets with contraindications — cardiac conditions, active cancer, kidney involvement, drug interactions — can end up on peptides that aren't right for them. And the legitimate science gets undermined when the industry gets associated with shortcuts.
We're trying to build the version that respects both the science and the responsibility.
How we're different
- Licensed DVM review on every order. Not a "consult your vet" disclaimer — actual veterinary judgment before anything ships.
- Willing to decline orders. If a pet's profile isn't a good fit for the protocol they've requested, we don't sell to them. We'd rather lose a sale than ship to a pet who shouldn't receive it.
- Research-backed, not hype-driven. Our content cites primary sources. We're honest about what the research does and doesn't show. We don't claim peptides cure conditions — we share what the science actually supports.
- Complementary to your primary vet. We're not a replacement for conventional veterinary medicine. We're a wellness layer that works alongside your dog or cat's existing care.
- 100% money-back guarantee. If it doesn't work for your pet, we'll refund you. No quibbling.
The team
Companion Peptide is operated by Brinoxa Holdings LLC, based in Southern California. We work with a network of licensed integrative veterinarians who handle protocol review and customer communication. A more detailed founder note will be added here — for now, if you'd like to know more about who we are or how we operate, the best way is to reach out directly.
Want to know more?
The fastest way to see how this works is to tell us about your pet. The intake form takes a couple of minutes, and a DVM will follow up directly.
