Lab TestingMostly unchecked so far · 45% verified5216% 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: Reports come from Horizon Analytical and BTLabs. At least one of these labs is ISO/IEC 17025 accredited.
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: Not yet checked.
How many lab reports the seller has published. More reports means more of its products have been checked.
What we found: Not yet counted.
How recent the newest report is. Old reports may not match what is being sold today.
What we found: Not yet checked.
Whether you can see the lab reports before you buy, without making an account.
What we found: Reports are not shown publicly.
Testing DepthMiddle of the road · 50% verified5912% 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: Estimated from the Peptide Source Review audit grade until we review the reports ourselves.
Confirms the vial holds the compound on the label and not something else. Measured with mass spec.
What we found: Estimated from the Peptide Source Review audit grade until we review the reports ourselves.
How many milligrams are really in the vial compared with what the label says.
What we found: Estimated from the Peptide Source Review audit grade until we review the reports ourselves.
A common kind of contamination left behind by bacteria. Measured with the LAL test. Clean products have very little.
What we found: Estimated from the Peptide Source Review audit grade until we review the reports ourselves.
Checks that nothing is growing in the product, like bacteria or mold.
What we found: Estimated from the Peptide Source Review audit grade until we review the reports ourselves.
Checks for lead, arsenic, cadmium and mercury.

Results vs Our StandardMostly unchecked so far · 0% verified358% 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: Not yet checked.
Our bar is within 10% of the label. A 10 mg vial should hold between 9 and 11 mg.
What we found: Not yet checked.
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 RecordMiddle of the road · 100% verified669% 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: Less than a year in business (brand-new in 2026).
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 · 0% verified357% 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: Not yet checked.
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 PolicyMostly unchecked so far · 0% verified304% 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: Not yet checked.
Whether the seller welcomes customers sending products to their own lab, and refunds products that fail.
What we found: Not yet checked.
Business TransparencyWeak · 70% verified474% of score
Is it a real company you could find and contact?

Price CompetitivenessStrong · 50% verified854% of score
How do their prices compare with the market average?
Lower prices are better for buyers. We compare each seller's prices with the market average across a basket of common products. Price is scored on its own, like every other area, and never changes how testing is scored.

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 48 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 (less than a year in business) but the checks already add up below it.
Pinnacle Peptide Labs earns a D (48 out of 100) and ranks #71 of 104. It loses the most points on outside blind tests (30), testing depth (59) and business transparency (47).
We verified 49% of what we check, so confidence is provisional. 7 areas are still mostly unchecked (lab testing, results against our standard, report honesty, buyer protection, testing policy, support and website); they use a below-middle placeholder until our daily checks confirm the facts.
What would raise the score most
- Get products tested blind by an independent testing program.up to +11.2
- Publish a separate lab report for every batch, with the lot number on it.up to +2.8
- Only release batches that test at 99% purity or higher.up to +2.6
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.
