Nano-encapsulated peptide delivery

They gave you
their best years.
Give them more.

Swallowed on their own, peptides are destroyed by stomach acid long before they can do anything. PET-Tides wraps each one in a nano-encapsulated shell engineered to carry it through the gut and release it intact — where it can actually be absorbed.

A few drops in the water bowl. No pills to hide. No needles. No fight.
No mixing, no measuring, and no 30-day clock.

The problem nobody mentions

Most oral peptides never reach your dog.

Peptides are fragile chains of amino acids. Swallowed unprotected, the vast majority are dismantled before absorption — which is exactly why serious peptide protocols have always meant a needle and a vet visit.

PET-Tides drops

The dose on a label is not the dose that arrives. Delivery is the whole game.

The other thing nobody solves

Most peptides die in a month.

Traditional peptides arrive as a freeze-dried powder you mix yourself. The moment you do, a clock starts — and it's a short one.

The traditional way

  • Arrives as powder in a sealed vial
  • You reconstitute it with bacteriostatic water
  • Refrigerated, and the countdown starts
  • Roughly 30 days before it degrades
  • Whatever's left is thrown away
  • Syringes, measuring, a calendar

PET-Tides liquid

  • Arrives ready to use in a dropper bottle
  • Nothing to mix, measure or reconstitute
  • Arrives premixed — store as labelled
  • Stable for 12+ months
  • Every drop gets used
  • Squeeze, count, done

That stability isn't luck. The same matrix that shields the peptide from stomach acid protects it in the bottle — so what you pour on day 300 is what you poured on day one.

503BOutsourcing
Facility

Compounded in an FDA-registered 503B facility.

Most supplements are made in a plant nobody inspects. Ours are compounded in an FDA-registered 503B outsourcing facility — a category the FDA registers, inspects, and holds to cGMP, the same manufacturing regulations that govern pharmaceutical drugs (21 CFR Parts 210 and 211).

It is a materially higher bar than the 503A compounding pharmacies most peptide sellers use, which answer only to a state board and never face a federal inspection.

FDA-registered facility Subject to FDA inspection cGMP manufacturing Batch-tested for purity
The transport pathway

Six barriers stand between a peptide and a cell.

From the moment it's swallowed, a peptide runs a gauntlet. Here's every obstacle — and how our encapsulation is engineered to get past each one.

Stage
The barrier
How we get through
In the bowl

Barrier 1 · Product stability

Peptides must be stabilised at a bioavailable size and protected from degradation before they're even swallowed.

Protected from the start

A nano-sized micellar hydrocolloid shell forms around the peptide — one that disperses instantly and uniformly through water.
Stomach

Barrier 2 · Compound stability

Up to two hours in acid at pH 1–3, plus pepsin and digestive enzymes, plus mechanical churning. Most peptides end here.

Passes straight through

The cross-linked matrix forms a steric barrier against acid and enzymes, and moves through without triggering the pyloric valve or a digestive response.
Small intestine

Barrier 3 · Absorption

Particles must shrink enough to be absorbed — without bile salts and proteolytic enzymes denaturing the peptide on the way.

Disassembles on cue

The shell comes apart cleanly in the intestine, and the particle size allows rapid uptake at the microvilli without requiring enzymes.
Portal vein & liver

Barrier 4 · First-pass metabolism

Whatever survives is routed to the liver, where enzymes catabolise or modify it before it ever reaches circulation.

Takes the other road

The micellar hydrocolloid is absorbed via the lacteal and funnelled through the lymphatic system into blood — bypassing the first-pass gauntlet.
Bloodstream

Barrier 5 · Systemic distribution

Peptides must be distributed through the body and taken into tissue before the kidneys clear them out.

Releases its payload

The carrier dissociates in the blood, separating the oil fraction from the peptide fraction and freeing the active peptide to circulate.
Interstitial fluid

Barrier 6 · Lymphatic clearance

The peptide has to be used by the cells before it's drained back into the lymph and recirculated away.

Delivered to the cell

Circulating peptides are absorbed into tissue and interstitial fluid for rapid delivery — where they can finally interact at the cellular level.
Anatomy of the particle

Three layers, one job.

Every drop carries millions of these. Each is built to stay sealed where it must, and open where it should.

60–300 nanometres
1

Functional nano-micellar core

The bioactive payload sits in a micellar structure able to bind both lipid-soluble and water-soluble actives together in one stable centre.

2

Cross-linked hydrocolloid matrix

Polysaccharide chains bind electrostatically into a three-dimensional gel network that traps water, reinforces structural integrity, and forms a steric barrier shielding the core from the harsh gastric environment.

3

Hygroscopic interface layer

An outer coating that holds moisture, keeps the particle flexible, promotes mucosal adhesion, and lets it disperse evenly the instant it meets water.

Tap or hover the numbers to see each layer.

Engineered to overcome

Five jobs, done at once.

Every layer of the particle exists to solve a specific failure point in oral peptide delivery.

Formulated to support the systems that slow down first — joints, recovery, and the everyday spark that makes a dog feel like themselves.

🦴

Joint comfort & mobility

Supports healthy joint function and connective tissue in dogs whose stairs have gotten taller and whose walks have gotten shorter.

💪

Recovery & resilience

Supports the body's normal repair processes after activity — so a big afternoon at the park doesn't cost them the next two days.

Coat, skin & vitality

Supports overall wellness and a healthy skin and coat — the visible signs that things are working properly underneath.

Our story

It started with the dog in this picture.

That's River, on our front steps. Every bottle of PET-Tides exists because of him.

Millions of dogs age the way nobody warns you about — fast. One season the stairs get slower, then the walks get shorter, and a family watches the dog who helped raise their kids deteriorate in fast-forward. We're told that's just what dogs do. I don't accept that.

I started this company because I wanted to do everything in my power to give River the healthiest life a dog can have — without pain, without discomfort, without watching him fade before his time. Building that for one dog meant we could offer it to every family who loves theirs the way we love ours.

That's the company. That's the whole reason.

How to use

Drops in the bowl. That's the entire protocol.

Dosing scales with body weight. Add to fresh water once daily, or straight onto wet food if your dog is a slow drinker.

Under 25 lb
2–3
drops daily250 mcg
a bottle lasts ~4 months
25 – 50 lb
5
drops daily500 mcg
a bottle lasts ~2 months
50 – 75 lb
8
drops daily750 mcg
a bottle lasts ~6 weeks
Over 75 lb
10
drops daily1,000 mcg
a bottle lasts ~1 month

Each drop carries 100 mcg. A 30 mg bottle holds 300 drops, so it stretches from about a month for a big dog to four months for a small one. Dosing follows the weight-based framework used in integrative veterinary practice. Introduce any new supplement gradually, and check with your vet first.

Protocols

How long to run it, product by product.

Dosing is set by your dog's weight. Duration is set by what you're treating — a torn tendon and a dull coat are not the same job. Here's how we'd run each one.

1

Load · weeks 1–8

Full weight-based dose, every day, no days off. This is the window where owners typically start noticing something — rarely before week four.

2

Assess · week 8

Compare against where you started, not against yesterday. Film your dog on the stairs in week one so you have something honest to measure against.

3

Maintain · ongoing

If it's working, keep going. Some products are run continuously, others step down once you've got the result. The table below says which.

ProductPeptideRun it forThen
MOVEJoints & mobilityBPC-157 8 weeks daily Continue daily. Mobility is a maintenance problem — it comes back when you stop.
REPAIRSoft tissueBPC-157 + TB-500 Through the recovery window — typically 6–12 weeks Step down to MOVE for long-term joint maintenance once the injury has settled.
COATSkin & coatGHK-Cu 8–12 weeks Coat runs on a full hair-growth cycle, so give it the longer end before judging. Maintain daily or seasonally.
CALMAnxietySelank Daily, ongoing Build a steady baseline rather than dosing only on storm days — it isn't a sedative and doesn't work as a rescue dose.
MINDCognitionSemax Daily, ongoing Cognitive support is maintenance, not a course. Start earlier than you think you need to — you're holding ground, not winning it back.
GUARDImmuneThymosin Alpha-1 8 weeks on Run through recovery, kennel season, or whenever your dog is under load, then rest and repeat as needed.
Can I run two at once?

Yes — MOVE and MIND, or COAT and GUARD, are common pairings. Dose each to weight separately; don't split a single dose between two products.

What if I miss a day?

Carry on the next day at the normal amount. Don't double up. Consistency across weeks matters far more than any one day.

Do I need to cycle off?

Only GUARD is built around on/off blocks. The rest are run continuously for as long as they're helping.

These are starting points, not prescriptions. PET-Tides is a supplement, not an approved drug, and nothing here diagnoses or treats disease. If your dog is on medication, pregnant, nursing, or has a known or suspected tumour, talk to your veterinarian before starting — see the safety note in our FAQ.

Tested

Every lot is tested. Every bottle comes with the paperwork.

The supplement aisle asks you to take its word for it. We don't. Each production lot is assayed before it's filled, and the Certificate of Analysis for that lot ships with your order — the same document a compounding pharmacy would hand a physician.

🧬

Identity

Confirms the peptide in the bottle is the peptide on the label — the correct amino-acid sequence, not a look-alike or a blend.

📊

Purity & potency

HPLC assay showing how much active peptide is actually present. This is where most consumer supplements quietly fall short.

🏷️

Lot traceability

Every bottle is stamped with a lot number that ties back to a specific production run, a specific test date, and a specific result.

🏛️

Compounded under federal oversight

Produced in an FDA-registered 503B outsourcing facility — a site that is FDA-inspected and operates under cGMP, unlike a supplement plant that answers to no one.

Guarantee

If it doesn't help your dog, you don't pay for it.

Give it a full 90 days. If it didn't help your dog, you get your money back — including the bottle you already opened. The guarantee's full details are shown right at checkout, before you ever pay a dollar.

Ninety days rather than thirty for a reason: supplements take four to eight weeks to show anything, so a month-long guarantee expires before you'd know. We'd rather give you long enough to actually judge it.

Real dogs

Real dogs. Real progress. On film.

Words are easy — footage isn't. This is where PET-Tides dogs show their progress: the stairs they stopped avoiding, the walks that got longer, the mornings that got easier. Filmed by the people who know them best.

Questions

The things people actually ask.

Why drops instead of a chew or a powder?

Two reasons. First, dogs refuse chews they don't like, and a supplement your dog won't eat does nothing at all. Second and more importantly, the encapsulation that protects the peptide works in liquid suspension — it disperses through the water and stays sealed until the intestine. A dry powder can't do that.

Will my dog notice it in the water?

It's designed to be tasteless and odourless once dispersed, and the particle is built to disperse evenly rather than sit on the surface. Most dogs drink normally without hesitating. If yours is unusually particular, add the drops to wet food instead.

How is this different from peptide injections at the vet?

Injectable peptide protocols are administered by a veterinarian and are a different category entirely. PET-Tides is an oral supplement you give at home. If your dog is under veterinary care or taking medication, speak with your vet before adding anything new.

What actually is a peptide?

A short chain of amino acids — the same building blocks that make up protein, just in much shorter sequences. Because they're short and specific, peptides can act as signals, binding to receptors and prompting a particular response. The difficulty has never been whether they work; it's getting them where they need to go without being digested first.

Is there any dog who shouldn't take this?

Yes, and we'd rather say so plainly. BPC-157 works partly by encouraging new blood vessel growth — that's a large part of how it helps tissue repair. Because of that, veterinary sources advise caution in any dog with a known or suspected tumour, since in theory the same mechanism could support existing abnormal tissue. Senior dogs are our customers and seniors have higher cancer rates, so please have your vet screen your dog before starting. Also speak to your vet first if your dog is pregnant, nursing, or on medication.

How long does a bottle last, and does it expire?

A 30mg bottle runs roughly 30 to 120 days depending on your dog's weight — about four months for a small dog, about a month for a large one. Unopened or opened, it stays stable for 12 or more months stored as directed — no mixing, no measuring, nothing to prepare. That's the part traditional peptides can't match: once you reconstitute those yourself they're good for roughly 30 days, and the rest gets thrown away.

Why would I choose the injectable over the drops?

Price, mostly. If you already run peptide protocols and you're comfortable reconstituting a vial and giving a subcutaneous injection, the injectable costs meaningfully less. It's the same peptide. What you give up is the convenience and the shelf life — you'll be mixing it with bacteriostatic water, keeping it refrigerated, and using it within about 30 days. For most dog owners the drops are worth the difference.

What if it doesn't work for my dog?

You get your money back. Give it the full 90 days, and if it didn't help, email info@pet-tides.dog for a full refund — opened bottle included. The guarantee's documentation details are shown at checkout.

How long before I see anything?

Supplements work gradually. Most owners give it four to eight weeks of consistent daily use before judging. Give it a fair run.

What ages and sizes is it for?

Formulated with older dogs in mind — generally seven and up, and earlier for large breeds, who age faster. Dosing scales by body weight.

Can I give it to my cat?

The current formula is dosed and tested for dogs. Cats metabolise many compounds quite differently, so we're not making claims outside what we've formulated for.
