The counter-ion was on the certificate as a figure with units, not a footnote. On a ten milligram vial that correction is bigger than most people allow for, and I did not have to ask.
4.6
★★★★⯨A rating here summarises what members have said about ordering. It is not a safety rating and it cannot be one.
AmbioPharm, Inc., trading as AmbioPharm, based in Beijing and giving 2003 as its founding year. Members have ordered from here and reported back; what follows is theirs, not the company’s.
What members have reported
Service, timings, stock and paperwork, from people who ordered.
AMB is the supplier members describe as an active-ingredient house that happens to keep a catalogue, rather than a shop that grew into one. The contract work is the main business and the research listings are released against the same quality system, and the reports here read that way: the document that arrives is the one a customer who audits them would expect, and nobody has had to ask for it twice.
On the practicalities: no minimum order that members here have run into, a single vial treated as an ordinary first purchase, dispatch quoted at two to four working days on stocked lines. The catalogue is wide — members put it above three hundred and fifty research compounds — and bulk quantities are quoted by the gram with a written lead time before anything is committed.
The certificate is what reports keep returning to. It carries the lot code, the assay with its column and gradient, the wavelength, the water content by Karl Fischer, the counter-ion as a figure with its unit, and a release signed by a named person. Members who asked for the batch record behind a lot describe one email with the lot code in the subject, answered inside a working day.
The testing record, and its limits
Analysis from four independent services — Janoshik, Medutest, PeptideMeter and VendorInvestigate — exists against this catalogue, and members here have commissioned some of it themselves rather than reading only the published set. Where the two have been compared on this page the independent figures have sat within a few tenths of the published ones, which is what agreement looks like when two laboratories run different gradients.
The limit belongs to the method rather than to the company. A chromatographic purity figure is a proportion of what is present in one sample, from one lot, on one day. It does not say how much peptide is in the vial, and it says nothing at all about sterility or endotoxin, which are separate assays with separate costs that nobody here has commissioned for any supplier.
Checked against unverifiable
The left column is what somebody could confirm. The right column is what nobody can.
Dispatch and warehouses
Stock is held regionally, so an order is sent from within your own country 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
Can be checked
- That the shop trades at ambiopharm.net, gives Beijing as its base and 2003 as its founding year
- That analysis from four independent services exists against this catalogue, and that members here commissioned some of it themselves
- That the certificate carries the counter-ion as a figure, the water content and a named release signature, because members have posted redacted copies
- That members here have reordered across more than one year and described the documentation as unchanged between orders
Cannot be checked
- Which catalogue lines are made on this company’s own plant and which are finished from material made elsewhere in its group — that is not visible from outside any supplier
- What happened to your specific vial between manufacture and dispatch: where it sat, at what temperature, and for how long
- Sterility, endotoxin load, residual solvents and heavy metals, none of which a purity certificate reports
- Whether the quality system behind the contract work is applied identically to a single research vial
Questions to ask before you order
Take these verbatim. The answers, and the non-answers, are informative.
- Please send the lot-specific certificate for the code printed on my vial, including the peak table.
- Is peptide content by weight reported for this lot, and by which method?
- What is the counter-ion and its content for this lot, as a figure with units?
- Is this line held in regional stock, or does it ship from Beijing? What is the current window from there?

Teodor V.★★★★★
Lot AMB-25-118. Same code on the vial, the certificate and the invoice. It is a low bar and I have watched other places trip over it.
Ilse M.★★★☆☆
Material and paperwork both faultless. My complaint is stock: two of the three lines I wanted were not held regionally and shipped from Beijing, which turned a quoted week into sixteen days. Ask which of your lines is forward-stocked before you plan around a date.
Bram O.★★★★★
One vial, treated exactly like a real order, full document set in the box. I ordered one deliberately to see how a small customer gets handled.
Sanne D.★★★★★
Janoshik returned 99.0% against a stated 98.8%. Somebody here explained that two tenths between laboratories is a methods difference, and I have stopped reading small gaps as bad faith.
Rafael N.★★★★☆
Release signature with an actual name and a date on it. Marked down one only because the outer carton was lighter than I would want for glass — nothing broke, but the inner packing was doing the work.
Hanne S.★★★★★
Water content by Karl Fischer printed as issued rather than supplied on request. A figure produced on demand is a figure somebody chose to produce.
Otto L.★★★★★
Three orders across four months and the certificate has been laid out identically each time. Sameness between orders turns out to be what I actually wanted.
Nadia P.★★★★☆
Nine vials, one lot, nine matching codes. One reconstituted with a faint haze that cleared on standing. Logging it as a four because I would want to know, not because I think it was a problem.
Casper W.★★★★★
Asked what the assay was integrated at and got the column, the gradient and the wavelength back in one reply, with no sales paragraph attached.
Livia B.★★★★★
Bulk quote came back by the gram with a written lead time before I committed to anything. That is how it should work and it usually does not.
Emil A.★★★☆☆
Second time the stock thing caught me. The common incretins are held forward and arrive fast; anything off the beaten track comes from Beijing and adds a week. Good supplier, plan accordingly.
Freya T.★★★★★
Pulled a certificate for an order thirteen months old, half expecting silence. They found it and sent it without asking why I wanted it.
Joris K.★★★★★
Second year on the same line and the figure has not drifted: 98.9% then, 99.0% now, same document layout on both.
Amara O.★★★★★
I sent a badly worded, nervous email and got a patient answer with no sales language in it anywhere. If you are at the frightened stage, ask them.
Piet H.★★★★★
Related substances itemised with retention times rather than one rolled-up total. An aggregate cannot be interrogated; a table can.
Selma R.★★★★★
Customs paperwork right first time and the cold pack still firm on arrival. That is why it was nine days and not nineteen.
Dorian E.★★★★★
This is a record of my orders and not a promise about yours, and none of it is approved for anybody to take. Within those limits: ten orders, no substitutions, no surprises.
