No independent test of Swiss Chems' LL-37 yet
- LL-37 generally tests around 99.3% purity across 1 independent certificate — but from other makers, so treat it as a benchmark, not proof of this seller's stock.
- Price sits within the normal range for LL-37 — no cheap-fake red flag.
How to verify this yourself
To verify before you buy: ask Swiss Chems for the Janoshik COA for your batch number, then paste it into Verify — VialGrade confirms it's a real, unedited lab record.

Every LL-37 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 17 are here: the last 4 are listings whose vendor never published a strength we can read, so they have no per-mg figure to sort on.

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 LL-37?
Preclinical / animal onlya.k.a. Cathelicidin, hCAP-18 (precursor form)Your body's own built-in antibiotic — a molecule the immune system uses to punch holes in microbes and rally immune cells. Studied for infections and wound healing.
Good to know: Native LL-37 is cytotoxic and hemolytic at higher concentrations and degrades rapidly in vivo, which is why most therapeutic development uses modified analogs rather than the native peptide.
How does LL-37 work?
The science
The only human cathelicidin antimicrobial peptide; it disrupts microbial membranes directly and also signals through the formyl peptide receptor FPRL-1/FPR2 to recruit and activate immune cells.
Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.
What is LL-37 researched for?
Studied for broad-spectrum antimicrobial, antiviral, wound-healing, and immunomodulatory applications.
- Immune & thymicStudied in immune-modulation and thymic-function research.
- Recovery & healingStudied in tissue-repair research — tendon, ligament, muscle, and wound-healing models.
How far has the research gone?
Preclinical / animal research — extensively studied in vitro and in animal wound/infection models, but poor stability and toxicity have kept it from clinical translation.
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.
These certificates are for LL-37 across every maker VialGrade tracks — not necessarily Swiss Chems’s own stock. This listing’s specific evidence is the matrix above.
Independent testing
Independent lab tests on record for LL-37
Real, publicly verifiable third-party tests. Purity is read from the certificate itself. A test reflects one lab’s result for one submitted batch — not a guarantee that every vial matches.
How does this data get here?
Every record below is a real certificate of analysis, gathered two ways: from the public verification feeds that independent labs (like Janoshik) publish, and from the certificates vendors post on their own product pages. We open each certificate document and read the measured purity, content, batch, and date directly off it — a scraper can’t read a number printed inside an image, so this is done by machine vision, then recorded here with a link back to the original.
Nothing here is typed in by a vendor or invented by us. Where a certificate is missing, we say so rather than filling the gap.
We re-check the lab feed, too. A “still listed” tag means the certificate is currently public in Janoshik’s database — we re-verify against the live feed and stamp the date. If a cert is later pulled, the tag flips. It’s a freshness check on the same source, not a second independent opinion.
What a certificate does & doesn’t prove
Three different questions. Purity (“how clean?”), identity (“is it the right molecule?”, a mass-spec test), and content (“did I get the labeled mg?”) are separate. A vial can be 99% pure and still be the wrong peptide, or the right peptide underdosed. We flag the measured dose against the label above; underdosing is the most common real fraud.
Who submitted the sample matters. Most of these are vendor-submitted — the seller chose which vial to send, so one good certificate doesn’t prove every batch is the same. The gold standard is a blind test, where a buyer sends a vial they bought as a normal customer. Same label doesn’t prove same product; same batch number doesn’t prove same batch.

No test for this vendor — but LL-37 is independently characterized
This vendor doesn't advertise independent testing, and we hold no COA tied to Swiss Chems specifically. We do hold 1 independent certificate for LL-37 (median 99.3% purity) from other makers — real market context for what this compound tests at, though not proof of this vendor's product.
- This vendor. No third-party COA on record for Swiss Chems.
- LL-37 (market-wide). 1 independent COA, median 99.3%.
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.
