The research, read it yourself
Twenty-nine compounds, sorted by one honest measure: how strong the dog-and-cat evidence actually is. We don't pretend a viral peptide is proven just because owners ask about it. Below, every product opens its full file — how it works, every study as a clickable link to PubMed or PMC, the honest read from owners on Reddit, and how to use it safely.
So we grouped the whole catalogue into three tiers, loudest part out loud: Best evidence (green) — real published efficacy in dogs or cats; Emerging (yellow) — huge owner demand (BPC-157, CJC-1295, ipamorelin, semaglutide) but the data is PK, safety, other-species or class-level, not a finished pet efficacy trial; and Experimental (grey) — wanted by name, but no direct dog-or-cat study exists yet. This is a design prototype, not a working store, and nothing here is veterinary advice.
We start from the dog or cat, not the molecule
A peptide being trendy somewhere on the internet means nothing here. Every compound is judged on the same four honest gates in dogs or cats — and instead of hiding the ones it doesn't fully clear, we put them in a louder, lower tier and say so, because pretending otherwise is how pets get hurt.
Published veterinary evidence
There must be peer-reviewed work in actual dogs or cats — controlled trials, clinical studies, or validated diagnostics. If the only data is human or rodent, we say so and we don't pretend it transfers.
Sorted into an honest tier
A handful of cases is not an RCT. So every compound carries a tier badge — green for real dog-or-cat efficacy (topical GHK-Cu, feline L-carnitine), yellow when the loud owner demand outruns the data and all we have is PK, safety or class-level evidence (BPC-157, semaglutide, ipamorelin), and grey when there's no direct pet study at all (TB-500).
A dose and format that fits the animal
Every compound has to make sense for a real dog or cat — a sensible route, a sensible dose, and a format owners can actually use at home. If we can't present it in a usable, pet-appropriate form, it doesn't earn a vial.
Tested, traceable, never “research chemical”
Every batch is third-party tested and carries a PupCode — no name on the vial, the PupCode on the cap tells your Passport exactly what's inside. We never traffic in unlabeled powders sold off a forum.
One more piece of honesty: alongside the journals we read the rooms where owners actually talk — Reddit, breeder forums, condition-specific groups. That sentiment is not evidence and we never treat it as such, but it tells us where real demand, real confusion, and real safety worries live. Both reads are in every file below.
The Evidence Hub
All 29 products, grouped by their evidence tier — its tier badge, compound, and complete research disclosure. Deep-link any one of them straight from its product page — science.html#<product>.
Read the tiers literally. Best evidence (green) means real published efficacy in dogs or cats. Emerging (yellow) means there is loud, genuine owner demand — these are the most-asked-about pet peptides — but the evidence is pharmacokinetic, safety-only, other-species or class-level, not a finished dog-or-cat efficacy trial. Experimental (grey) means there is no direct dog-or-cat study at all yet; it's here because owners ask for it by name, and we'd rather list it honestly than let a forum sell it to you blind.

Where every word above came from
Peer-reviewed veterinary literature
Each compound's mechanism, benefit and safety are drawn from published studies in dogs and cats — cited inline as clickable cards that open the original PubMed or PMC record. We link the source, name the journal, and summarise the finding without inflating it. Where the strongest data is still human, rodent, or a single small study, the file says so out loud.
Reddit & owner sentiment
We read r/AskVet, r/dogs, r/cats, r/Peptides, breeder forums and condition-specific groups to capture what owners are actually asking and worrying about. This is sentiment, not evidence — it shapes our honesty, never our claims. When the organic pet conversation is thin or mostly human, we tell you that too.
Puptides is a design prototype, not a real store, and nothing here is veterinary advice.
The science and the studies are real; the storefront is a concept. Results vary by animal. Always talk to your vet before starting, changing or stopping anything — they know your pet; we don't.
You've seen the receipts. Now find the fit.
Tell us your pet and your goal and we'll point you at the club and the one or two compounds that actually have the evidence.
