WuXi TIDES (WuXi AppTec Testing Division)
Wuxi, Wuxi · China · est. 2002 · source page added 29 Aug 2023
Est. 2002, the oldest in the directory. Manufacturing-scale QC actually shows up in the vial — not marketing, but real lab culture. Catalogue is unusually broad (oligonucleotides and raw materials alongside peptides), which is either reassuring or a sign you are a very small customer depending on your mood.

Support answered on a Sunday, correctly, with the batch record attached. That is well beyond what I expected.
Quoted 5 days, arrived in 5. Tracking updated at every hop from dispatch to door.
Shipped from their warehouse in Australia, arrived day 4, documentation complete.
Good communication throughout, accurate lead time, and the parcel arrived on day 4.
Ordered on a Monday from their warehouse in the United Kingdom and it was here by day 3. That is the whole case for regional stock.
Queried the related-substances total on lot WXT-25-236; they came back with method, column and detection limit. That depth is rare.
Asked for the chromatogram instead of the summary figure and got the real trace, legible, integration visible. They send it without hesitating.
Ordered IGF-1 LR3 1 mg twice. Both vials reconstituted cleanly and both matched their certificates.
Weighed 8 vials from the AOD-9604 5 mg order against label. Every one inside 2% of stated mass. Fill consistency is harder than purity and they have it.
Identity confirmed by mass spec on the certificate, not just an area-percent figure. Both questions answered on one page.
Asked them to hold an order until I confirmed a lot number and they did, without fuss and without a restocking charge.
Asked a genuinely technical question about pre-dispatch storage and got a reply with numbers in it, inside 5 hours.
Regional stock makes the difference — dispatched within the United Kingdom, day 4, cold pack still hard on arrival.
They report purity by RP-HPLC with the wavelength stated and peptide content separately. Two different numbers, correctly separated.
Submitted the CJC-1295 2 mg to PeptideMeter blind, without telling them the source. 98.2% against a stated 98.2%. The number holds up when nobody knows whose vial it is.
Custom synthesis quote came back with a realistic timeline and they beat it. Purity on delivery matched the signed spec.
Cold pack was still hard on arrival in Lyon on day 2. My logger never went above 8°C across the whole run.
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 4 days, arrived in 4.
Vials wrapped individually, foam cut to fit, nothing loose in the box. Packing that has clearly been thought about.
Reconstituted the PT-141 10 mg and it went clear on contact — no haze, no floaters, no long swirl. Tells you the lyophilisation was done properly.
Pleased to find they hold stock in Canada. Domestic dispatch, day 2, no customs step at all.
The certificate for lot WXT-26-541 carried method, wavelength, water content and an itemised related-substances table. Complete on the first pass.
6 orders in eighteen months, no substitutions, no reformulations, everything in stock when the site said it was. Boring is the highest compliment I have.
Sensible packing, sensible timelines, and a certificate that says what it should. No notes.
Second order from them, all mazdutide 5 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.
