No independent test of Core Peptides' Sermorelin yet
- Sermorelin generally tests around 99.2% purity across 4 independent certificates — but from other makers, so treat it as a benchmark, not proof of this seller's stock.
- Price sits within the normal range for Sermorelin — no cheap-fake red flag.
How to verify this yourself
To verify before you buy: ask Core Peptides for the Janoshik COA for your batch number, then paste it into Verify — VialGrade confirms it's a real, unedited lab record.

Every Sermorelin 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 30 are here: the last 5 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 Sermorelin?
FDA-approved moleculea.k.a. GerefA lab-made copy of the brain's 'release growth hormone now' signal. It was once an approved drug (Geref); today it mostly appears in anti-aging clinics and research settings.
Good to know: No FDA-approved version is currently marketed; current supply is compounded or research-grade material not subject to the same manufacturing oversight.
How does Sermorelin work?
The science
A synthetic 29-amino-acid analog of GHRH (GHRH 1-29); binds the GHRH receptor on pituitary somatotrophs to stimulate the body's own pulsatile GH release.
Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.
What is Sermorelin researched for?
Studied historically for diagnosing and treating growth hormone deficiency; used in ongoing research and compounding for GH-axis support and body composition.
- Growth hormone supportStudied for how it interacts with the body's own growth-hormone axis in research settings.
How far has the research gone?
FDA-approved historically (for growth hormone deficiency); marketed as Geref from 1997 until discontinued from the market in 2008 for commercial (not safety) reasons.
Where the science stands — an approved drug is not the same as the research-grade material a vendor sells, which is unregulated regardless.
What is Sermorelin commonly stacked with?
Compounds the research community frequently discusses alongside Sermorelin. Not a protocol or a recommendation — a map of what to read about next.
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 Sermorelin across every maker VialGrade tracks — not necessarily Core Peptides’s own stock. This listing’s specific evidence is the matrix above.
Independent testing
Independent lab tests on record for Sermorelin
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 Sermorelin is independently characterized
This vendor doesn't advertise independent testing, and we hold no COA tied to Core Peptides specifically. We do hold 4 independent certificates for Sermorelin (median 99.2% 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 Core Peptides.
- Sermorelin (market-wide). 4 independent COAs, median 99.2%.
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

This is a prescription drug in the US
This is a formerly FDA-approved drug — an FDA-approved prescription medication. Buying a “research” version sidesteps the prescription requirement and the approved, quality-controlled supply chain. The FDA has warned about and acted against unapproved and compounded copies. Higher legal and safety exposure than an unapproved research peptide.
