counter ion on the cert as a figure with units. on a 10 mg vial that correction is bigger than most people allow for and i did not have to ask

Straight to the source, in a new tab. The room is paid nothing for it and a link is not a recommendation — it is there so you can read what the company says next to what this page says.
What the room says
A Beijing active-ingredient house that has been making peptide API to contract since 2003 and keeps a research catalogue off the same quality system, and that shows up in the certificate before it shows up anywhere else. The counter-ion is on the document as a figure with units, which almost nobody else in this directory does, and the release is signed by a named person rather than initialled. That is most of the case for them here: the paperwork habits are borrowed from a business where a customer can audit you. What #vendor-talk actually argues about is forward stock — the common incretins are held regionally and land fast, everything else comes out of Beijing and adds about a week, and people keep planning the second on the timings of the first.
Dispatch & warehouses
Regional stock. Orders leave a warehouse in the member’s own country.
- 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
Consistently praised
- Counter-ion stated as a figure with units, which most of this directory omits entirely
- Assay has landed at or above the certificate on every lot logged since 2025
- Release signature carries a name and a date rather than an initial
Worth knowing before you order
- Forward stock is thinner than average — ask which of YOUR lines is held regionally rather than shipped from Beijing, the gap is about a week
- Bulk and API quantities are quoted by the gram with a written lead time before you commit
- The certificate carries purity by RP-HPLC with the wavelength, net peptide content, water by Karl Fischer, counter-ion and the lot code — the batch record comes back on request

asked what the assay was integrated at and got column, gradient and wavelength back in one reply. no upsell bolted on the end which i noticed because it never happens
ignacio_g★★★☆☆2026-05-12
material fine paperwork fine. stock is the issue. two of three lines werent held regionally, came from beijing, quoted week turned into sixteen days. ask before you plan
dario_c★★★★★2026-04-08
release signed with an actual name and a date. not an initial. somebody put their name on it
diego_l★★★★★2026-03-17
day 9 to the UK, cold pack still hard, customs right first time which is why it was 9 not 19
soren_b★★★★☆2026-02-21
nine vials one lot nine matching codes. one had a faint haze on reconstitution that cleared on standing. logging it because id want to know. n=1
fabio_n★★★★★2026-01-15
batch record back inside a working day with the lot code in the subject. didnt have to ask twice which is apparently the bar now
nils_c★★★★★2025-11-28
second year same line. 98.9 then 99.0 now, same cert layout both times. drift is the thing i watch for and there isnt any
gustav_h★★★★★2025-10-04
related substances itemised with retention times not "total 0.5%" and good luck. research use only obviously
nayeli_m★★★★★2026-07-09
lot AMB-26-118. cert matched vial matched invoice. no notes. will order again
petra_a★★★★☆2025-09-16
all good on the material. one off because the outer carton was lighter than i want for glass. nothing broke but the inner packing did the work
arne_me★★★★★2026-04-27
peptide content listed separately from purity. two numbers correctly separated. should not be rare and yet
kenji_o★★★★★2025-08-21
first order deliberately tiny to see how a one vial customer gets treated. full document set same as anyone. second order was not tiny
annika_y★★★★★2026-06-02
bulk quote came back by the gram with a written lead time before i committed to anything. thats how it should work
gustav_d★★★★★2025-12-11
pulled a cert for an order 13 months old. found it, sent it, no attitude about why i wanted it
elise_g★★★★★2026-03-03
sent one vial to medutest and one to vendorinvestigate because i didnt trust a single number. a tenth apart
cesar_a★★★★★2025-07-19
reconstituted the semaglutide and it went clear on contact. no swirl nothing floating. properly dried cake
greta_g★★★★★2026-05-18
water by karl fischer printed as issued not on request. a number produced on demand is a number somebody chose to produce

Where AMB sells
AmbioPharm, Inc. sells from its own storefront. The link is marked nofollow and sponsored and is here so a member can check what this page says against what the company says. The room is paid nothing for it and a link is not a recommendation.
Whatever the storefront says, check the lot on the vial against the lot on the certificate before you use anything.
Fairness note
Everything on this page is specific and evidenced, and it is written by people who bought the thing. The room keeps its words apart: a shipping question is a shipping question, and fraud is a separate matter dealt with in #scam-watch, which concerns impersonators, lookalike domains and forged certificates rather than any of the 28 companies in this directory. Nothing here is medical advice, and research-use-only material is not approved for human use.
