Shanghai ERP Biotechnology Co., Ltd.

First order was deliberately small. Documentation complete, transit as quoted, Medutest returned 99.1%. Subsequent orders have not been small. Research use only; these are not approved for human administration.

Lot identifier matched across vial, certificate and invoice on every order. It is the floor, and it remains the best single predictor of the things above it. Invoice, vial and certificate agree on the lot without exception. I will update this post if a later lot changes the picture.

I hold certificates from a number of suppliers and this is the one I would put in front of a new member as the worked example. On the evidence I hold they are the default rather than the risk.

Cold chain held to arrival on day 8, with the pack still solid, in a month when that cannot be assumed. Scoped to the lots named. Not generalised beyond them.

Water content by Karl Fischer was on the first certificate with the method named, alongside the purity figure. Two determinations rather than one, without having to ask for the second.

Compared direct-supply material at 99.7% against an intermediary vial of nominally identical description at 99.3%. Offering the comparison without drawing a conclusion for anyone else.

Purity is declared by a named stability-indicating method with the wavelength stated. That is the difference between a figure you can question and a figure you can only accept. The Janoshik report is on file and matches the figures they published. One member, one record, offered as such.

Submitted material from lot ERP-25-425 to Janoshik. Result 98.1% against a declared 98.3%, which is inside the repeatability of the method rather than a disagreement with it. Regional stock is held for the lines I reorder, so a factory run is off the critical path.

Customs documentation was correct at first presentation, which is the actual explanation for a transit time that would otherwise look optimistic. Nothing here is medical advice and I am not qualified to give any.

Reconstitution of the NAD+ 500 mg produced a clear solution on contact — no haze, no particulate, no extended agitation. Consistent with a correctly executed lyophilisation. Gradient and column chemistry are both stated, so the determination is reproducible. No complaint arises from the orders described.

Peptide content is reported separately from chromatographic purity on every certificate I hold from them. Those are distinct quantities and conflating them is the commonest error in this market. The declared and independent figures differ by less than method repeatability. Documentation practice rather than a single purity figure is the substance of this.

Every unit in the consignment carried a single lot identifier, so the intra-consignment comparison I intended was the comparison I made. Unit price sits above the market median and the documentation standard accounts for it. Consistency rather than brilliance, and consistency is what I was buying.

They gave notice of a 2-day dispatch delay before the quoted window elapsed rather than after. Recording it because the sequence is the part that matters. The VendorInvestigate report is on file and matches the figures they published. I have no relationship with this supplier beyond having paid them.

Cross-checked one lot with VendorInvestigate and Janoshik independently. Agreement to a tenth of a point, and both agree with the declared figure. Regional stock is held for the lines I reorder, so a factory run is off the critical path. Happy to answer follow-ups in the thread rather than by message.

The related-substances table is itemised by individual impurity with retention times assigned, rather than reported as a single total. Vial-to-vial mass variation across the consignment under two per cent. No complaint arises from the orders described.

Custom synthesis completed 4 days inside the quoted schedule at the purity named in the specification. Peptide content declared at 97.8%, so conversion to working mass required no assumption. I will update this post if a later lot changes the picture.

Ordered AOD-9604 5 mg from stock held in Germany. Quoted 8 days, delivered day 8, tracking accurate at every hop. Catalogue availability corresponded to the published catalogue.

Repeat determination on the same line at 6 months returned 97.7%, against 97.7% originally. No drift visible in this sample. Scoped to the lots named. Not generalised beyond them.

Been buying ipamorelin 5 mg here since before the catalogue expanded. The expansion has not cost the original lines anything measurable. Water content is reported by Karl Fischer with the method named. Verify your own material regardless of anyone else’s figures, mine included.

Scoping this to documentation only: the certificate carries a stability statement tied to a named storage condition, which is more than the minimum and more than most of the certificates in my folder. Documentation practice rather than a single purity figure is the substance of this.

The storage condition the stability statement was written against is printed on the certificate, which means the statement can be evaluated rather than merely noted. Vial-to-vial mass variation across the consignment under two per cent. One member, one record, offered as such.

Packing on the consignment: the caps crimped evenly, none of them proud of the shoulder. Designed rather than inherited. Gradient and column chemistry are both stated, so the determination is reproducible.

Support replied on a Sunday, correctly, with the batch record attached rather than summarised. Catalogue availability corresponded to the published catalogue.

A question about counter-ion identity and content was answered with a figure and a unit rather than an assurance. Reorder at 14 months landed within a tenth of a point of the original. Happy to answer follow-ups in the thread rather than by message.

Nothing about this order was notable and I am recording it for that reason. Quoted timeline held, documentation correct, material as described. I will update this post if a later lot changes the picture.

Cold chain held to arrival on day six with the pack still solid. Recording it because a cold chain that works is invisible and a cold chain that does not is all anyone writes about.
