Lab TestingMiddle · 11.6 of 19 pts61of 100
Does an outside lab test every batch, and can you see the reports?
Reports come from ILS Laboratories.
What this means
An outside lab is a testing company the seller does not own. "Accredited" means an official body inspected the lab and certified its accuracy.
Publishes a separate report for each batch.
What this means
A batch (or lot) is one production run. A report for each batch shows the product you would get was tested, not just an old sample.
No lab reports published.
What this means
How many lab reports the seller has published. More reports means more of its products have been checked.
No dated reports found.
What this means
How recent the newest report is. Old reports may not match what is being sold today.
Reports are visible after a simple age check.
What this means
Whether you can see the lab reports before you buy, without making an account.
Testing DepthNothing found · 0.0 of 16 pts0of 100
Does testing go past the basics into contamination?
No purity (hplc) results found.
What this means
How much of the vial is the actual compound. Measured with HPLC, the standard lab method for purity.
No identity (mass spec) results found.
What this means
Confirms the vial holds the compound on the label and not something else. Measured with mass spec.
No net content results found.
What this means
How many milligrams are really in the vial compared with what the label says.
No endotoxin results found.
What this means
A common kind of contamination left behind by bacteria. Measured with the LAL test. Clean products have very little.
No sterility results found.
What this means
Checks that nothing is growing in the product, like bacteria or mold.
No heavy metals results found.
What this means
Checks for lead, arsenic, cadmium and mercury.
No raw-material reports found.
What this means
A report on the raw powder before it is filled into vials. Catches a bad batch at the source. Only published reports count, not a promise.
Results vs Our StandardMiddle · 3.0 of 6 pts50of 100
Do the published results meet our fixed standard?
Too few reports with purity results to judge.
What this means
Our bar is 99% purity or higher, which means no more than 1% of the vial is anything other than the labeled compound.
Too few reports list the measured amount to judge.
What this means
Our bar is within 10% of the label. A 10 mg vial should hold between 9 and 11 mg.
Independent Blind TestsNothing found · 0.0 of 14 pts0of 100
When someone bought it anonymously and had it tested, did it match the label?
No independent blind tests on record.
What this means
Someone buys the product anonymously, like a normal customer, and sends it to a lab. The seller cannot pick a "good" vial to send, so this is the hardest proof to fake.
Report VerifiabilityNothing found · 0.0 of 10 pts0of 100
Can you confirm the reports are real?
No verifiable reports found.
What this means
Whether the lab's own website confirms the report is real. Fake and edited reports are common in this market.
No report archive found.
What this means
Whether older reports stay online. Sellers that delete old reports can hide bad results.
No reports to check.
What this means
Signs that a report was faked, edited or reused for a different product.

Buyer ProtectionStrong · 5.3 of 7 pts75of 100
If something goes wrong, can you get your money back?
Takes cards (Visa, Mastercard, American Express, USDT, ACH or bank transfer, Wire transfer, Other), so charges can be disputed.
What this means
Paying by credit or debit card lets you ask your bank to reverse the charge if something goes wrong. Zelle, bank transfers and crypto cannot be reversed by your bank, so with those the seller's refund policy is what protects you.
Says it does not reship lost orders.
What this means
A promise to send your order again if it gets lost or seized in shipping.
Written policy offers full refunds.
What this means
Whether the seller promises, in writing, to give your money back, and how much.

Cards plus backup options: bank transfer or Zelle, crypto.

Neutral for now. Each photo-verified vote moves this a little, and the tally shows once enough buyers have voted.
