No independent test of Simple Peptide's Larazotide yet
- We hold no independent tests for Larazotide from any maker yet — unknown stays visible.
- We couldn't place this listing's price — its size isn't readable or the market's too thin — so there's no cheap-fake check here.
How to verify this yourself
To verify before you buy: ask Simple Peptide for the Janoshik COA for your batch number, then paste it into Verify — VialGrade confirms it's a real, unedited lab record.

Hands you to simplepeptide.com — VialGrade doesn’t sell or take payment
Some vendor links may earn VialGrade a commission. It never changes a grade, a price, or where a listing ranks.

Every Larazotide listing, cheapest per mg first
Sticker prices hide the size, so listings are ranked by what a milligram actually costs — with independently tested purity where it exists. All 2 are here: the last 1 is a listing whose vendor never published a strength we can read, so it has no per-mg figure to sort on.
| # | Vendor | Size | Price | Per mg | Tested purity | Real $/active mg | |
|---|---|---|---|---|---|---|---|
| 1 | Behemoth LabzUnavailable | 10mg total | $112 | $11.2/mg | — | — | View |
| Listed, but not rankable — no published strength to price per mg | |||||||
| — | Simple Peptide | 1 vial | $169 | no size published | — | — | View |
Real $/active mg divides the price-per-mg by the measured purity — the honest cost of the actual peptide, so a 90%-pure vial isn’t compared as if it were 99%. Too cheap? flags a listing far below the market rate — often underdosing or a fake, not a deal. The crown marks the cheapest non-outlier; best value marks the lowest real cost per active mg. A vendor shown as Unavailable or Low stock is priced here but not currently buyable.
Understand this compound
What is Larazotide?
In clinical trialsa.k.a. Larazotide acetate, INN-202A molecule that helps tighten the seams between the cells lining your gut. Studied in celiac disease for calming so-called leaky gut.
Good to know: It is studied as an adjunct to, not a replacement for, a gluten-free diet, and has not been shown to fully prevent gluten-triggered intestinal damage.
How does Larazotide work?
The science
An eight-amino-acid peptide that acts as a zonulin antagonist, helping regulate tight-junction proteins in the intestinal epithelium to reduce gut permeability.
Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.
What is Larazotide researched for?
Studied as an adjunct therapy for celiac disease to reduce gluten-triggered intestinal permeability and symptoms.
- Gut healthStudied in gastrointestinal research, including gut-lining integrity and inflammatory-condition models.
How far has the research gone?
In clinical trials — has reached Phase 3 trials for celiac disease, with a favorable safety and tolerability profile across Phase 1-3 studies.
Where the science stands — an approved drug is not the same as the research-grade material a vendor sells, which is unregulated regardless.
What should I check before buying?
- Independent purity. Look for a third-party COA (Janoshik or MZ) showing a measured purity — not just a number the vendor typed.
- Batch match. The strongest evidence is a certificate for the exact batch you’ll receive, attributed to this vendor — check the cross-verification on the listing.
- Vendor reputation. See how the vendor is talked about in the community before trusting a new name.
Research context only — VialGrade never gives dosing, medical, or human-use guidance.
The lab evidence
What we could verify
Each row is a separate question with its own answer — one green row never vouches for the rest.
Identity
UnknownNo independent test on record for this listing.
Measured purity
UnknownNo independent purity measurement on record.
Batch traceability
UnknownNo batch on this listing matches an independent record.
Sterility
Not testedA purity certificate doesn't measure this — no such test on record.
Dose accuracy
UnknownNot something VialGrade measures — no test on record.
No third-party testing to cross-check
This listing doesn't advertise independent lab testing, and we don't hold an independent record for Simple Peptide's Larazotide. Absence of a certificate isn't proof of anything — but there's nothing here to verify.
- Independent testing. No third-party COA advertised or on record.
Cross-checks the vendor’s testing claim against independent lab records. Read from the certificate, not re-measured by VialGrade. Purity is not a grade. Never a statement that a product is safe, sterile, or correctly dosed. What “grade” actually means

Research-use-only — not FDA-approved
Sold “for research use only,” this compound is not FDA-approved for human use and has not been evaluated for safety, purity, or sterility in people. It is generally not a scheduled controlled substance, so buying it as a research chemical is typically not itself a drug crime — but marketing or using it as a drug is not lawful, and it is not a dietary supplement.
General information, not legal or medical advice. VialGrade sells nothing and encourages no human use.
