Ordered GHK-Cu 50 mg twice. Both vials reconstituted cleanly and both matched their certificates.

Documentation quality
Certificates are issued on a consistent template with method, system suitability summary and a reference to the analytical procedure identifier. Content assay is offered alongside purity on request, which almost nobody else in this directory does.
Maintainers' assessment
Verified across all four services. The oldest establishment date here (2002) and the only supplier whose documentation regularly distinguishes a purity assay from a content assay. Records span 24 months without an unresolved discrepancy.
Community reviews
26 reviews from members with a record on this site. Aggregate rating 9.5 of 10 across 913 reviews.
Reliable on the general catalogue lines. Purity figures cluster tightly and the certificates match the lots.
Shipped from their warehouse in Australia, arrived day 3, documentation complete.
Solid on the KPV 10 mg. Purity where it should be, transit 2 days, paperwork in order.
Reconstituted the GHK-Cu 50 mg and it went clear on contact — no haze, no floaters, no long swirl. Tells you the lyophilisation was done properly.
Vials wrapped individually, foam cut to fit, nothing loose in the box. Packing that has clearly been thought about.
Cold pack was still hard on arrival in Cork on day 4. My logger never went above 5°C across the whole run.
Everything about the order was routine in the best sense — quoted 3 days, arrived in 3.
Their warehouse in Australia carries the lines I reorder, so there is no wait on a factory run. Day 5 every time.
Fair pricing for the documentation standard, and delivery landed on day 4 as quoted.
Reordered on the strength of the last one and got an identical result. Repeatability is the product.
Pleased to find they hold stock in the United States. Domestic dispatch, day 2, no customs step at all.
Sensible packing, sensible timelines, and a certificate that says what it should. No notes.
Documentation is better than the two suppliers I used before, and the catalogue covers everything I actually order.
They report purity by RP-HPLC with the wavelength stated and peptide content separately. Two different numbers, correctly separated.
Held locally in the United States, so the sermorelin 5 mg arrived on day 5 without an import step.
The NAD+ 500 mg arrived on day 4 with the cold pack intact and the seal unbroken. Straightforward, exactly as described.
PeptideMeter has now seen 8 of their lots through me. Not one has come back outside spec.
Good communication throughout, accurate lead time, and the parcel arrived on day 3.
Seventh order from them, all mazdutide 5 mg. Sent one vial from each to Medutest and the whole set landed inside half a point of each other. That flatness is exactly what I pay for.
Domestic dispatch from their stock in Germany. Straightforward, day 4, exactly as quoted.
Documentation is complete and the numbers are steady. A dependable choice for routine work.
Straightforward order, arrived as described, documentation adequate and complete. Nothing to add, which is the point.
Consistent rather than flashy. Everything lands in the high nineties, and it lands there every time.
Peptide content reported at 98.9% alongside the purity figure, so I could convert straight to a working mass.
5 lots logged now, purity 98.8 to 99.0%. A band that tight is worth more to me than one spectacular number.
Where WXT sells
WuXi TIDES (WuXi AppTec Testing Division) sells from its own storefront. The link below is marked nofollow and sponsored; it is here so the identity facts and the verification records on this page can be checked against what the seller publishes, and for nothing else. This site is paid nothing for it.
Whatever a storefront claims, the lot on the vial has to match the lot on the certificate. That check is yours and nobody else can do it for you.

To add a record, file a structured report in vendor reports with the compound, lot, service, method and result. Reports missing any of those are moved to the discussion rather than the record. Allegations without documentation are hidden under R6 and the hiding is logged.
