QST — member reviews
93% from 462 member reports. 26 are published in full below; the rating aggregates all of them. Reviews without an order date or a testable claim are not counted.
This community's number, not a fleet-wide one. Independent groups scoring the same vendor land within a few tenths of each other, and where they diverge it is usually because one group weights logistics and another weights purity consistency.
9 lots logged now, purity 99.3 to 99.4%. A band that tight is worth more to me than one spectacular number.
Vials wrapped individually, foam cut to fit, nothing loose in the box. Packing that has clearly been thought about.
Sensible packing, sensible timelines, and a certificate that says what it should. No notes.
The selank 10 mg arrived on day 5 with the cold pack intact and the seal unbroken. Straightforward, exactly as described.
Support answered on a Sunday, correctly, with the batch record attached. That is well beyond what I expected.
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.
Quoted 4 days, arrived in 3. Tracking updated at every hop from dispatch to door.
Documentation is complete and the numbers are steady. A dependable choice for routine work.
Everything about the order was routine in the best sense — quoted 4 days, arrived in 3.
Ordered KPV 10 mg twice. Both vials reconstituted cleanly and both matched their certificates.
Moved here after two bad lots elsewhere. 4 orders in and the Medutest numbers have been flat every single time.
Their warehouse in Canada had the MOTS-c 10 mg in stock and it shipped the same afternoon. Tracking never left the country.
Stock said available, stock was available, and it shipped the same day. That sequence is not as common as it should be.
Janoshik has now seen 4 of their lots through me. Not one has come back outside spec.
Arrived on day 2 against a quoted 3. Customs paperwork was right first time, which is why it moved that fast.
First order, deliberately small, GHK-Cu 50 mg only. Documentation, transit and a PeptideMeter result at 99.2% all checked out, so the next one will not be small.
Third order and it went the same way as the first two. Predictable in the way you want a supplier to be.
Steady supplier. Medutest results have agreed with their stated figures on every lot I have submitted.
Fair pricing for the documentation standard, and delivery landed on day 4 as quoted.
Ordered on a Monday from their warehouse in the Netherlands and it was here by day 2. That is the whole case for regional stock.
The certificate for lot QST-26-895 carried method, wavelength, water content and an itemised related-substances table. Complete on the first pass.
Sixth order from them, all tesamorelin 2 mg. Sent one vial from each to Janoshik and the whole set landed inside half a point of each other. That flatness is exactly what I pay for.
One of the few places that will quote selank 10 mg at all, and the synthesis came back clean on an independent check.
Reliable on the general catalogue lines. Purity figures cluster tightly and the certificates match the lots.
Dispatched from their warehouse in Australia rather than from the factory, so the BPC-157 5 mg was with me on day 3.
Consistent rather than flashy. Everything lands in the high nineties, and it lands there every time.
What a useful review looks like
Order date, what was ordered, what arrived, how long it took, and whether anything was independently tested. That is it. "Great vendor, fast shipping, A+++" is worth nothing and gets removed; a three-star review explaining precisely what went wrong and how it was handled is worth more than ten five-star ones.
Why the negative ones stay up
A directory of nothing but praise is a marketing brochure. Every source page here carries the disappointing results as prominently as the good ones, and the vendors near the top of the ranking are there because their bad entries are few and old, not because there are none.
Where QST sells
Qingdao Saber Technology Pharmaceutical sells from its own storefront. The link below is marked nofollow and sponsored and is here so you can read what they say about themselves against what this page says about them. GLP Research Hub is paid nothing for it, and a link is not a recommendation.

A good record predicts your batch. It does not guarantee it, and no storefront can. Check the lot on the vial against the lot on the certificate.
