9 orders in eighteen months, no substitutions, no reformulations, everything in stock when the site said it was. Boring is the highest compliment I have.

What the room says
A steady mid-tier presence in the log since 2024. The room's notes are mostly about process: order confirmations arrive, invoices match, tracking works. Purity results are good without being remarkable. Nothing dramatic has ever happened, which is the entire review.

Third order and it went the same way as the first two. Predictable in the way you want a supplier to be.
malin_r★★★★★2025-08-20
7 lots logged now, purity 99.2 to 99.7%. A band that tight is worth more to me than one spectacular number.
tobias_d★★★★★2026-02-11
Lot code on the vial matched the lot code on the certificate exactly. Sounds basic; it is the single best predictor of everything else.
nikhil_c★★★★☆2026-01-30
Fair pricing for the documentation standard, and delivery landed on day 4 as quoted.
hassan_b★★★★★2025-09-14
Regional stock makes the difference — dispatched within the United Kingdom, day 4, cold pack still hard on arrival.
ewan_b★★★★★2026-04-14
Ordered on a Monday from their warehouse in Australia and it was here by day 2. That is the whole case for regional stock.
teodor_e★★★★★2025-02-15
Documentation is better than the two suppliers I used before, and the catalogue covers everything I actually order.
kenji_a★★★★★2025-10-04
First order, deliberately small, BPC-157 5 mg only. Documentation, transit and a PeptideMeter result at 99.0% all checked out, so the next one will not be small.
bianca_a★★★★★2025-04-08
Shipped with a stated storage recommendation and a shelf-life figure tied to it, without my asking.
yusuf_ba★★★★★2026-05-02
Their warehouse in Canada had the retatrutide 5 mg in stock and it shipped the same afternoon. Tracking never left the country.
ruben_c★★★★★2026-01-05
Asked for the chromatogram instead of the summary figure and got the real trace, legible, integration visible. They send it without hesitating.
astrid_r★★★★★2025-04-03
Cold pack was still hard on arrival in Dublin on day 3. My logger never went above 8°C across the whole run.
aleksi_v★★★★★2025-10-07
Asked a genuinely technical question about pre-dispatch storage and got a reply with numbers in it, inside 9 hours.
lukas_f★★★★★2025-03-07
Seventh order from them, all semaglutide 5 mg. Sent one vial from each to PeptideMeter and the whole set landed inside half a point of each other. That flatness is exactly what I pay for.
maren_o★★★★★2025-03-07
Certificate claimed 98.1% on lot ERP-24-293. PeptideMeter came back 98.5%. On an independent column that is as close to agreement as this gets.
enzo_s★★★★★2025-12-06
The certificate for lot ERP-26-378 carried method, wavelength, water content and an itemised related-substances table. Complete on the first pass.
maren_p★★★★☆2026-05-01
Ordered ipamorelin 5 mg twice. Both vials reconstituted cleanly and both matched their certificates.
runa_b★★★★★2025-06-15
Quoted 4 days, arrived in 3. Tracking updated at every hop from dispatch to door.
kenji_n★★★★★2026-02-16
Moved here after two bad lots elsewhere. 4 orders in and the PeptideMeter numbers have been flat every single time.
matias_a★★★★★2025-12-01
Reordered on the strength of the last one and got an identical result. Repeatability is the product.
wanjiru_b★★★★★2025-06-09
Stock said available, stock was available, and it shipped the same day. That sequence is not as common as it should be.
isabela_a★★★★★2025-09-22
Arrived on day 2 against a quoted 3. Customs paperwork was right first time, which is why it moved that fast.
yannick_k★★★★★2025-10-03
Reconstituted the survodutide 5 mg and it went clear on contact — no haze, no floaters, no long swirl. Tells you the lyophilisation was done properly.
soren_r★★★★★2025-12-05
Support answered on a Sunday, correctly, with the batch record attached. That is well beyond what I expected.
rohan_r★★★★★2025-07-17
No customs paperwork, no import wait — it came from their stock in the Netherlands and arrived day 3.

Where ERP sells
Shanghai ERP Biotechnology Co., Ltd. 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.
Visit ERP at erpbiotechnology.com →
Whatever the storefront says, check the lot on the vial against the lot on the certificate before you use anything.
Fairness note
Criticism on this page is specific and evidenced. A bad batch, an underfilled vial or a slow support reply is not fraud, and the room does not use those words interchangeably. Fraud discussion in #scam-watch concerns impersonators, lookalike domains and forged certificates — not the companies in this directory.
