Reordered on the strength of the last one and got an identical result. Repeatability is the product.

What the room says
Qingdao, 2017, and the log is genuinely mixed rather than bad. Purity has never been the problem. Fill consistency has been, twice, and both times were handled properly. The room's position is that they are fine if you weigh your vials, which is advice it would give about anyone.

Cold pack was still hard on arrival in Gothenburg on day 4. My logger never went above 6°C across the whole run.
Reliable on the general catalogue lines. Purity figures cluster tightly and the certificates match the lots.
Queried the related-substances total on lot QST-26-272; they came back with method, column and detection limit. That depth is rare.
The semax 10 mg arrived on day 2 with the cold pack intact and the seal unbroken. Straightforward, exactly as described.
Steady supplier. PeptideMeter results have agreed with their stated figures on every lot I have submitted.
Custom synthesis quote came back with a realistic timeline and they beat it. Purity on delivery matched the signed spec.
6 lots logged now, purity 98.9 to 99.0%. A band that tight is worth more to me than one spectacular number.
Certificate claimed 98.9% on lot QST-25-529. Medutest came back 99.2%. On an independent column that is as close to agreement as this gets.
Shipped from their warehouse in Australia, arrived day 4, documentation complete.
Moved here after two bad lots elsewhere. 3 orders in and the Medutest numbers have been flat every single time.
Asked a genuinely technical question about pre-dispatch storage and got a reply with numbers in it, inside 8 hours.
Lot code on the vial matched the lot code on the certificate exactly. Sounds basic; it is the single best predictor of everything else.
Quoted 3 days, arrived in 2. Tracking updated at every hop from dispatch to door.
Vial labels printed rather than handwritten, lot and date legible, cap seal intact on every unit.
Shipped with a stated storage recommendation and a shelf-life figure tied to it, without my asking.
Everything about the order was routine in the best sense — quoted 3 days, arrived in 2.
Ordered on a Monday from their warehouse in the United States and it was here by day 3. That is the whole case for regional stock.
Arrived on day 4 against a quoted 5. Customs paperwork was right first time, which is why it moved that fast.
Straightforward order, arrived as described, documentation adequate and complete. Nothing to add, which is the point.
Asked for the chromatogram instead of the summary figure and got the real trace, legible, integration visible. They send it without hesitating.
Documentation is complete and the numbers are steady. A dependable choice for routine work.
First order, deliberately small, GHRP-2 5 mg only. Documentation, transit and a PeptideMeter result at 99.7% all checked out, so the next one will not be small.
Ninth order from them, all BPC-157 5 mg. Sent one vial from each to PeptideMeter and the whole set landed inside half a point of each other. That flatness is exactly what I pay for.
Ordered glutathione 600 mg twice. Both vials reconstituted cleanly and both matched their certificates.
Held locally in Germany, so the tesamorelin 2 mg arrived on day 4 without an import step.

Whatever the storefront says, check the lot on the vial against the lot on the certificate before you use anything.
