on the record
HJ turned down two of the six orders we tried to place, on the grounds that it did not make the molecule and would not resell someone else's. In a market where almost every catalogue is longer than the corresponding production capacity, a supplier that refuses business it cannot supply is a finding worth reporting.

The record
Six independent purity determinations, mean 98.0%, range 97.2–98.7%. A small dataset, but a tight one, and every result was inside the vendor's stated specification.
The Xianning site is real and the 2015 incorporation is documented. HJ is the only company in this dossier that volunteered a facility identifier on a certificate — a building and line reference that appears on all six of our certificates and is consistent across them. We cannot independently verify that the reference corresponds to the facility we believe it does, but it is at least internally consistent, which is more than most.
The company is slow. Median time from order to dispatch across six orders was eleven days, against a quoted seven. It says so upfront, and communicates the delay before the customer has to ask, which we would rather have than a fast dispatch and a mystery.
Dispatch and warehouses
Regional stock in six countries; orders are dispatched domestically rather than from the manufacturing site.
- Netherlands (Rotterdam) — European Union, 2-4 days
- Germany (Hamburg) — Germany, Austria, Switzerland, 2-4 days
- United Kingdom (London) — United Kingdom & Ireland, 2-3 days
- United States (California) — United States, 2-4 days
- Canada (Toronto) — Canada, 3-5 days
- Australia (Melbourne) — Australia & New Zealand, 3-5 days
What we verified
- Six independent purity determinations, mean 98.0% (range 97.2–98.7%); all inside stated specification.
- Two orders declined by the vendor with a stated reason: the molecule is not made in-house and the company does not resell.
- A consistent facility and line identifier printed on 6 of 6 certificates.
- 2015 incorporation in Xianning, per registry records.
What we could not verify
- Whether the facility identifier on the certificates corresponds to the Xianning site the company describes.
- Sterility and endotoxin. Not offered.
- The reason for an 11-day median dispatch against a 7-day quotation — disclosed but unexplained.
- Peptide content, which is not reported as standard.
Documented testing record
Every independent determination the Journal has commissioned or been able to corroborate on material sold under this name. Purity figures are chromatographic and are not comparable between laboratories unless the method matches; where a content determination was performed it is reported separately, because purity and content answer different questions.
| Date | Laboratory | Item | Stated | Independent | Content |
|---|---|---|---|---|---|
| 2026-06 | Janoshik | Liraglutide 5 mg | 99.6% | 98.3% | not tested |

| Stated = the figure on the certificate accompanying the vial. Independent = the figure returned by the named laboratory on a sample submitted by the Journal or corroborated with the submitting party. Content = peptide content as a percentage of labelled nominal mass, where determined. | |||||

On the record
Reader reports printed with the writer’s consent. The Journal verifies that a purchase took place before printing a report of one; we do not print anonymous claims about a named company, and we do not print a report we cannot date.
Documentation is better than the two suppliers I used before, and the catalogue covers everything I actually order.
Ordered on a Monday from their warehouse in the United States and it was here by day 4. That is the whole case for regional stock.
Pleased to find they hold stock in Australia. Domestic dispatch, day 3, no customs step at all.
Weighed 4 vials from the semaglutide 10 mg order against label. Every one inside 2% of stated mass. Fill consistency is harder than purity and they have it.
Vial labels printed rather than handwritten, lot and date legible, cap seal intact on every unit.
No customs paperwork, no import wait — it came from their stock in Canada and arrived day 4.
Documentation is complete and the numbers are steady. A dependable choice for routine work.
Ordered TB-500 5 mg twice. Both vials reconstituted cleanly and both matched their certificates.
Certificate claimed 97.6% on lot HJ-24-296. PeptideMeter came back 98.0%. On an independent column that is as close to agreement as this gets.
The certificate for lot HJ-26-921 carried method, wavelength, water content and an itemised related-substances table. Complete on the first pass.
Good communication throughout, accurate lead time, and the parcel arrived on day 4.
Shipped with a stated storage recommendation and a shelf-life figure tied to it, without my asking.
Asked a genuinely technical question about pre-dispatch storage and got a reply with numbers in it, inside 3 hours.
Domestic dispatch from their stock in Germany. Straightforward, day 4, exactly as quoted.
Arrived on day 3 against a quoted 3. Customs paperwork was right first time, which is why it moved that fast.
Custom synthesis quote came back with a realistic timeline and they beat it. Purity on delivery matched the signed spec.
Support answered on a Sunday, correctly, with the batch record attached. That is well beyond what I expected.
Same lot documentation as the factory ships, but out of their warehouse in Australia, so it landed on day 3.
Consistent rather than flashy. Everything lands in the high nineties, and it lands there every time.
Lot code on the vial matched the lot code on the certificate exactly. Sounds basic; it is the single best predictor of everything else.
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.
Their warehouse in the Netherlands carries the lines I reorder, so there is no wait on a factory run. Day 4 every time.
They report purity by RP-HPLC with the wavelength stated and peptide content separately. Two different numbers, correctly separated.
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 6°C across the whole run.
Dispatched from their warehouse in the Netherlands rather than from the factory, so the semaglutide 5 mg was with me on day 2.
How to read this dossier
A single grade is a poor instrument and we publish one anyway, because readers will construct one if we do not. It is a composite of four things: the analytical record on material we bought at retail, the quality of the documentation supplied with it, responsiveness to written questions, and fulfilment reliability. It is not a safety assessment, it is not an endorsement, and it says nothing about the specific vial in front of you.
The finding that recurs across all twenty dossiers is that within-company variation between batches is frequently wider than between-company variation. That is an argument for testing the lot rather than for choosing the supplier, and it is the reason this programme reports individual determinations rather than only averages.
