Lab TestingWeak · 100% verified016% of score
Do they test every batch at a real outside lab, and let you see the reports?
A lab report (a COA, certificate of analysis) is the only paper proof of what is in a vial. We want reports from a named outside lab, for every batch, that are recent and easy to see before you buy.
An outside lab is a testing company the seller does not own. "Accredited" means an official body inspected the lab and certified its accuracy.
What we found: We found no named outside lab on its reports.
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.
What we found: No batch-level reports found.
How many lab reports the seller has published. More reports means more of its products have been checked.
What we found: No lab reports published.
How recent the newest report is. Old reports may not match what is being sold today.
What we found: No reports to date.
Whether you can see the lab reports before you buy, without making an account.
What we found: Reports are not shown publicly.
Testing DepthWeak · 100% verified012% of score
Do their reports cover more than purity?
Purity alone does not tell you a vial is clean or correctly filled. A thorough seller also tests identity, net content, endotoxin, sterility and heavy metals. Each test counts only if it appears on real reports.
How much of the vial is the actual compound. Measured with HPLC, the standard lab method for purity.
What we found: No test results to review.
Confirms the vial holds the compound on the label and not something else. Measured with mass spec.
What we found: No test results to review.
How many milligrams are really in the vial compared with what the label says.
What we found: No test results to review.
A common kind of contamination left behind by bacteria. Measured with the LAL test. Clean products have very little.
What we found: No test results to review.
Checks that nothing is growing in the product, like bacteria or mold.
What we found: No test results to review.
Checks for lead, arsenic, cadmium and mercury.
What we found: No test results to review.
Results vs Our StandardWeak · 100% verified08% of score
Do their own results meet a strict, fixed standard?
Having reports is not enough. Every result is held to the same published standard: 99% purity or higher, and net content within 10% of the label.
Our bar is 99% purity or higher, which means no more than 1% of the vial is anything other than the labeled compound.
What we found: No reports to check against our standard.
Our bar is within 10% of the label. A 10 mg vial should hold between 9 and 11 mg.
What we found: No reports to check against our standard.
Outside Blind TestsWeak · 100% verified3016% of score
When someone else bought it anonymously and had it tested, did it match the label?
A vendor controls which vial it sends to its own lab. Blind tests of products bought at retail by independent testers are the hardest proof to fake. No outside tests means this category starts low.
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.
What we found: No outside blind test results on file yet. With no evidence either way, this area starts at 30, not 0, and rises only with real test results.
Report HonestyMostly unchecked so far · 20% verified4910% of score
Can you check the report is real, and match it to the vial you get?
Fake, edited and reused lab reports are the biggest trick in this market. We reward reports you can confirm on the lab's own website and batch numbers printed on the vial.
Whether the lab's own website confirms the report is real. Fake and edited reports are common in this market.
What we found: Not yet checked.
Whether the batch number printed on the vial matches a published report, so you know which report applies to your vial.
What we found: Not yet checked.
Whether older reports stay online. Sellers that delete old reports can hide bad results.
What we found: Not yet checked.
Signs that a report was faked, edited or reused for a different product.
What we found: No report red flags found in our sources.
Track RecordStrong · 55% verified719% of score
How long have they been around, and is their history clean?
Vendors that vanish take your money with them. Regulators also shut down sellers who market peptides for human use, so a regulatory warning letter is a real risk to buyers.
How long the business has been around. New sellers have no track record yet.
What we found: Not yet checked.
Whether a government regulator has sent the seller a warning letter in the last two years.
What we found: No regulatory warning letters found.
Documented problems, like orders that never arrived or sudden ownership changes.
What we found: No documented problems found in our sources.
Buyer ProtectionMostly unchecked so far · 45% verified647% of score
If something goes wrong, can you get your money back?
Credit cards let you dispute a charge. Zelle, crypto, Cash App and bank transfers do not. A written refund policy and a reship guarantee matter too.
Paying by credit or debit card lets you ask your bank to reverse the charge if something goes wrong. Crypto, Zelle and Cash App cannot be reversed.
What we found: Takes cards (Visa), so charges can be disputed.
A promise to send your order again if it gets lost or seized in shipping.
What we found: Not yet checked.
Whether the seller promises, in writing, to give your money back, and how much.
What we found: Not yet checked.
Testing PolicyWeak · 50% verified154% of score
Do they have a written testing protocol, and do they welcome buyers testing for themselves?
A seller with nothing to hide says exactly what every batch is tested for and where, and welcomes buyers who send vials to their own lab. Sellers that refund or replace a product that fails an outside test earn full points.
A written policy that says what every batch is tested for and which lab does the testing.
What we found: No written testing policy found.
Whether the seller welcomes customers sending products to their own lab, and refunds products that fail.
What we found: Not yet checked.
Business TransparencyWeak · 100% verified04% of score

Price CompetitivenessMostly unchecked so far · 0% verified504% of score

Community RatingNeeds 10 screened ratings first--3%
What do verified buyers say, privately?
Reviews are submitted privately and screened for fakes and competitor attacks. Only the positive and negative totals are public. This counts only after 10 screened ratings, and it can never outweigh the proof above.
How the score adds up
How 26 was calculated.
Each area is scored 0 to 100, then multiplied by its share. The three shares add up to the final score.
Community Rating (3%) is not counted yet, so the other checks are scaled up to fill 100%. That is why the shares above differ slightly from the 62 / 24 / 14 split.
A score limit applies (no outside lab proof) but the checks already add up below it.
GL Peptides earns an F (26 out of 100) and ranks #100 of 104. It does best on track record (71). It loses the most points on lab testing (0), testing depth (0) and outside blind tests (30).
We verified 72% of what we check, so confidence is medium. 5 areas are still mostly unchecked (report honesty, buyer protection, shipping, price competitiveness and website); they use a below-middle placeholder until our daily checks confirm the facts.

Buyer ratings
Not enough ratings yet (0 of 10 needed).
Every review needs a photo of the product label, and a person checks it. Reviews stay private: each one only adds a thumbs up or down to this tally, which counts for 3 of 100 points once there are 10.
