Shanghai ERP Biotechnology Co., Ltd.

Costed them per mg against three other suppliers on the same GHRP-2 5 mg spec. Competitive on price and clearly ahead on documentation.

Dispatched from their warehouse in the United States rather than from the factory, so the glutathione 600 mg was with me on day 2.

First order, deliberately small, BPC-157 10 mg only. Documentation, transit and a Medutest result at 99.0% all checked out, so the next one will not be small.

Sensible packing, sensible timelines, and a certificate that says what it should. No notes.

Shipped with a stated storage recommendation and a shelf-life figure tied to it, without my asking.

Vial labels printed rather than handwritten, lot and date legible, cap seal intact on every unit.

Third order and it went the same way as the first two. Predictable in the way you want a supplier to be.

Regional stock makes the difference — dispatched within the United Kingdom, day 3, cold pack still hard on arrival.

Fair pricing for the documentation standard, and delivery landed on day 4 as quoted.

Moved here after two bad lots elsewhere. 4 orders in and the PeptideMeter numbers have been flat every single time.

They report purity by RP-HPLC with the wavelength stated and peptide content separately. Two different numbers, correctly separated.

Custom synthesis quote came back with a realistic timeline and they beat it. Purity on delivery matched the signed spec.

Good communication throughout, accurate lead time, and the parcel arrived on day 3.

Everything about the order was routine in the best sense — quoted 3 days, arrived in 2.

Shipped from their warehouse in the United States, arrived day 2, documentation complete.

Ordered on a Monday from their warehouse in Canada and it was here by day 3. That is the whole case for regional stock.

Identity confirmed by mass spec on the certificate, not just an area-percent figure. Both questions answered on one page.

The NAD+ 500 mg arrived on day 4 with the cold pack intact and the seal unbroken. Straightforward, exactly as described.

Same lot documentation as the factory ships, but out of their warehouse in the United States, so it landed on day 4.

Reordered on the strength of the last one and got an identical result. Repeatability is the product.

Reliable on the general catalogue lines. Purity figures cluster tightly and the certificates match the lots.

Solid on the NAD+ 500 mg. Purity where it should be, transit 3 days, paperwork in order.

Every certificate I have from them is lot-specific. Not one batch-level document in 6 orders.

Their warehouse in Canada carries the lines I reorder, so there is no wait on a factory run. Day 2 every time.

Medutest has now seen 5 of their lots through me. Not one has come back outside spec.

Weighed 6 vials from the IGF-1 LR3 1 mg order against label. Every one inside 2% of stated mass. Fill consistency is harder than purity and they have it.
