First order, deliberately small, semax 10 mg only. Documentation, transit and a VendorInvestigate result at 98.7% all checked out, so the next one will not be small.

What the room says
The oldest operation the room deals with and it behaves like it. Documentation is the best of any supplier in the log — lot numbers legible, related-substances tables actually populated, and the COA date matches the lot. #coa-reading uses their certificates as the teaching example.

Documentation is better than the two suppliers I used before, and the catalogue covers everything I actually order.
soren_b★★★★★2025-09-08
Every certificate I have from them is lot-specific. Not one batch-level document in 7 orders.
fabio_n★★★★★2026-04-03
Their warehouse in the Netherlands carries the lines I reorder, so there is no wait on a factory run. Day 4 every time.
nils_c★★★★★2026-03-01
The retatrutide 5 mg arrived on day 4 with the cold pack intact and the seal unbroken. Straightforward, exactly as described.
gustav_h★★★★★2025-10-15
Support answered on a Sunday, correctly, with the batch record attached. That is well beyond what I expected.
nayeli_m★★★★★2026-03-18
Vials wrapped individually, foam cut to fit, nothing loose in the box. Packing that has clearly been thought about.
petra_a★★★★★2026-03-07
Asked a genuinely technical question about pre-dispatch storage and got a reply with numbers in it, inside 9 hours.
arne_me★★★★★2025-10-18
Weighed 5 vials from the LL-37 5 mg order against label. Every one inside 2% of stated mass. Fill consistency is harder than purity and they have it.
kenji_o★★★★★2026-02-02
Quoted 3 days, arrived in 3. Tracking updated at every hop from dispatch to door.
annika_y★★★★★2026-06-23
Queried the related-substances total on lot WXT-25-114; they came back with method, column and detection limit. That depth is rare.
gustav_d★★★★★2025-09-20
Tenth order from them, all NAD+ 500 mg. Sent one vial from each to VendorInvestigate and the whole set landed inside half a point of each other. That flatness is exactly what I pay for.
elise_g★★★★★2026-07-08
5 orders in eighteen months, no substitutions, no reformulations, everything in stock when the site said it was. Boring is the highest compliment I have.
cesar_a★★★★★2025-09-04
Shipped with a stated storage recommendation and a shelf-life figure tied to it, without my asking.
greta_g★★★★★2026-04-27
Regional stock makes the difference — dispatched within Australia, day 2, cold pack still hard on arrival.
hamza_ba★★★★☆2026-02-19
Good communication throughout, accurate lead time, and the parcel arrived on day 2.
erez_f★★★★★2025-05-19
Stock said available, stock was available, and it shipped the same day. That sequence is not as common as it should be.
ines_n★★★★☆2025-08-21
Reliable on the general catalogue lines. Purity figures cluster tightly and the certificates match the lots.
tomas_v★★★★★2026-04-09
Same lot documentation as the factory ships, but out of their warehouse in the Netherlands, so it landed on day 2.
elin_a★★★★★2025-05-22
The certificate for lot WXT-24-651 carried method, wavelength, water content and an itemised related-substances table. Complete on the first pass.
renzo_b★★★★★2026-07-12
One of the few places that will quote cagrilintide 5 mg at all, and the synthesis came back clean on an independent check.
gustav_i★★★★★2026-02-13
Reconstituted the KPV 10 mg and it went clear on contact — no haze, no floaters, no long swirl. Tells you the lyophilisation was done properly.
nora_d★★★★★2026-03-15
Submitted the PT-141 10 mg to VendorInvestigate blind, without telling them the source. 99.2% against a stated 99.0%. The number holds up when nobody knows whose vial it is.
aisha_p★★★★☆2026-04-11
Third order and it went the same way as the first two. Predictable in the way you want a supplier to be.
fatima_me★★★★★2025-06-01
Their raw material tested 99.4% against a reseller vial of nominally the same compound at 99.0%. Going direct is the whole argument.
enzo_a★★★★★2025-10-25
Asked them to hold an order until I confirmed a lot number and they did, without fuss and without a restocking charge.

Where WXT sells
WuXi TIDES (WuXi AppTec Testing Division) sells from its own storefront. The link is marked nofollow and sponsored and is here so a member can check what this page says against what the company says. The room is paid nothing for it and a link is not a recommendation.
Whatever the storefront says, check the lot on the vial against the lot on the certificate before you use anything.
Fairness note
Criticism on this page is specific and evidenced. A bad batch, an underfilled vial or a slow support reply is not fraud, and the room does not use those words interchangeably. Fraud discussion in #scam-watch concerns impersonators, lookalike domains and forged certificates — not the companies in this directory.
