Utility hook
Batch checker
Paste a batch code and check it against the current public database. Known published records resolve directly. Unknown records explain the next proof request.
Check a batchAustralian evidence index
Most peptide sites sell trust before they show proof.
When a supplier hides the batch, recycles a COA, pushes PayID or crypto before proof, or makes Australian dispatch impossible to verify, Peptide Checker shows the gap first.
01
Batch on the vial
No batch, no serious proof trail.
02
COA tied to that batch
Generic PDFs are not verification.
03
Payment with recourse
Crypto-only means the risk sits with you.
04
Real support route
A buyer needs an accountable operator.
Trust capture
Vendor scorecards
Every supplier gets the same public rubric: batch records, COAs, support, ownership, payment recourse, reviews, and right of reply.
Open scorecardsDefensibility
Public methodology
The ownership disclosure is visible, the criteria are public, and missing evidence is scored as missing evidence rather than turned into unsupported claims.

State of market
The peptide market is growing through therapeutics, longevity, aesthetics, creators, and grey-market import demand. The trust layer is the gap.

Open standardSupplier proof check
Put the supplier through the evidence filter.
This does not certify anyone. It tells the buyer whether the visible proof is strong, incomplete, or not worth touching yet.
Current verdict
0%Not enough proof yet.
Add visible evidence. If the batch, COA, label, payment, and supplier identity cannot be matched, the supplier has not earned trust.
Open vendor scorecardsThe market problem
The peptide market is crowded with labels. Very few sites show a full proof trail.
The weak operators all rely on the same shortcut: they ask the buyer to believe a purity number without proving the batch, lab report, payment record, dispatch route, and support system behind it.
Pretty labels are cheap.
A label can be printed overnight. A batch record has to survive matching, support, fulfilment, and buyer scrutiny.
COAs get recycled.
If the certificate is generic, cropped, old, or not tied to the vial, it is marketing collateral, not proof.
Local stock gets blurred.
Australian dispatch should be obvious before checkout. Long transit and vague origin language are not small details.
Payment reveals accountability.
The fastest way to see who carries risk is to look at the rail: card, bank transfer, PayID, crypto, or a private message.
Reviews do not replace records.
Forum comments, screenshots, and star ratings cannot verify the batch in your hand.
Cheap supply still has a cost.
When the price is far below documented supply, the missing cost is usually testing, support, fulfilment, or recourse.
The standard buyers should demand
The supplier standard is visible before checkout.
The point of Peptide Checker is not to make every other supplier look fake. The point is to make proof gaps obvious enough that serious buyers stop accepting weak records and demand a higher standard.

Hard questions
What a buyer should ask before ordering from any peptide site.
Does the COA match the exact vial?
If the batch number does not match the vial, product page, or order record, the certificate is not enough.
Can the seller prove local dispatch?
Australian stock should not be hidden behind vague shipping language, delayed tracking, or offshore packaging.
What happens if the order fails?
The payment rail, support route, refund policy, and order record show how much recourse the buyer actually has.
What does strong proof look like?
Visible product records, batch logic, purity language, local dispatch clarity, and support after the order.
No borrowed trust
