HJ — member reviews
97% from 642 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.
Reliable on the general catalogue lines. Purity figures cluster tightly and the certificates match the lots.
Ordered on a Monday from their warehouse in the Netherlands and it was here by day 4. 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.
Fifth order from them, all retatrutide 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.
Support answered on a Sunday, correctly, with the batch record attached. That is well beyond what I expected.
Their warehouse in Australia had the epithalon 10 mg in stock and it shipped the same afternoon. Tracking never left the country.
Peptide content reported at 99.7% alongside the purity figure, so I could convert straight to a working mass.
Asked them to hold an order until I confirmed a lot number and they did, without fuss and without a restocking charge.
One of the few places that will quote tirzepatide 15 mg at all, and the synthesis came back clean on an independent check.
Good communication throughout, accurate lead time, and the parcel arrived on day 4.
Moved here after two bad lots elsewhere. 6 orders in and the Medutest numbers have been flat every single time.
Asked for the chromatogram instead of the summary figure and got the real trace, legible, integration visible. They send it without hesitating.
Pleased to find they hold stock in Canada. Domestic dispatch, day 5, no customs step at all.
Ordered TB-500 5 mg twice. Both vials reconstituted cleanly and both matched their certificates.
PeptideMeter has now seen 7 of their lots through me. Not one has come back outside spec.
Stock said available, stock was available, and it shipped the same day. That sequence is not as common as it should be.
Weighed 4 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.
Quoted 5 days, arrived in 5. Tracking updated at every hop from dispatch to door.
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 Gothenburg on day 4. My logger never went above 4°C across the whole run.
8 orders in eighteen months, no substitutions, no reformulations, everything in stock when the site said it was. Boring is the highest compliment I have.
Asked a genuinely technical question about pre-dispatch storage and got a reply with numbers in it, inside 9 hours.
Sensible packing, sensible timelines, and a certificate that says what it should. No notes.
The certificate for lot HJ-24-741 carried method, wavelength, water content and an itemised related-substances table. Complete on the first pass.
They report purity by RP-HPLC with the wavelength stated and peptide content separately. Two different numbers, correctly separated.
Certificate claimed 97.5% on lot HJ-24-333. VendorInvestigate came back 97.7%. On an independent column that is as close to agreement as this gets.
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 HJ sells
Hubei Jianxiang Bioscience Co., Ltd. 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.
