What we know so far

No independent test of Nootropic Source's GHK-Cu yet

Nootropic Source carries a certificate-integrity flag on record — treat its claims with extra caution.
GHK-Cu generally tests around 99.7% purity across 14 independent certificates — but from other makers, so treat it as a benchmark, not proof of this seller's stock.
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 Nootropic Source for the Janoshik COA for your batch number, then paste it into Verify — VialGrade confirms it's a real, unedited lab record.

Cheapest GHK-Cu, by price per mg

Vials come in different sizes, so the sticker price lies. This ranks every listing by what a milligram actually costs — with independent test purity where we have it.

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.

Understand this compound

What is GHK-Cu?

Widely studieda.k.a. Copper peptide, GHK-Copper, Copper tripeptide-1

A copper peptide famous in skincare and hair research for collagen and cosmetic contexts, also discussed for tissue recovery. The 'GLOW' in the popular recovery blend.

Skin & cosmeticRecovery & healingLongevity & anti-aging

⚠

Good to know: Most positive human data come from small, often industry-sponsored topical cosmetic trials rather than large independent trials, and copper at high local concentrations can be pro-oxidant rather than protective.

How does GHK-Cu work?

A naturally occurring copper-binding tripeptide (Gly-His-Lys) that delivers copper to enzymes regulating extracellular matrix remodeling, stimulating fibroblast production of collagen, elastin, and glycosaminoglycans.

Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.

What is GHK-Cu researched for?

Studied for skin rejuvenation, wound healing, and hair growth.

Skin & cosmeticStudied in cosmetic and skin research — collagen, elasticity, and appearance.
Recovery & healingStudied in tissue-repair research — tendon, ligament, muscle, and wound-healing models.
Longevity & anti-agingStudied in aging, cellular-senescence, and mitochondrial-function research.

How far has the research gone?

Widely studied — decades of preclinical work plus several small human skin trials showing increased collagen density versus vehicle or retinoic acid controls.

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 GHK-Cu commonly stacked with?

Compounds the research community frequently discusses alongside GHK-Cu. 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 answers a different question. Passing the identity test doesn’t mean it’s sterile or correctly dosed — we show each answer separately.

Identity — independent test

Unknown

No independent third-party COA is advertised or on record for this listing.

Measured purity (HPLC)

Unknown

No independent purity figure is on record for this listing.

Batch traceability

Unknown

No specific batch on this listing has been matched to an independent record.

Sterility & endotoxin

Not tested

A purity COA does not measure sterility or endotoxins — no such test is on record.

Dose / fill accuracy

Unknown

VialGrade does not independently measure vial fill or delivered dose.

These certificates are for GHK-Cu across every maker VialGrade tracks — not necessarily Nootropic Source’s own stock. This listing’s specific evidence is the matrix above.

Independent testing

Independent lab tests on record for GHK-Cu

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.

Nothing to verify

No test for this vendor — but GHK-Cu is independently characterized

This vendor doesn't advertise independent testing, and we hold no COA tied to Nootropic Source specifically. We do hold 14 independent certificates for GHK-Cu (median 99.7% 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 Nootropic Source.
GHK-Cu (market-wide). 14 independent COAs, median 99.7%.

14 independent COAs on record for this compound · median 99.7% — see them all

Cross-checks the vendor’s testing claim against independent lab records. Purity is read from the lab's certificate as issued — VialGrade doesn't re-run the assay or sample the vial. It reflects one lab's result for one submitted batch, not every vial. Never a statement that a product is safe, sterile, or correctly dosed.

US legal status

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.
