Content equals the label
Purity (%) and content (the actual amount delivered) are not the same thing. We document both, so the amount on the label is the amount you receive — no quiet shortfalls.

Key Review Snapshot
Why buyers trust WUMO
In this market, “99% pure” is often quoted while the amount actually delivered is far less. We keep purity and real content separate, and put both on paper — so Tirzepatide / LY3298176 40mg Lyophilized Peptide Vial Supplier is backed by documents you can check.
Research peptide line — typical purity >99.3–99.4%, every batch MS-checked before release.
Purity (%) and content (the actual amount delivered) are not the same thing. We document both, so the amount on the label is the amount you receive — no quiet shortfalls.
Identity and quality are confirmed by batch documentation — COA, plus HPLC / MS where applicable — before material is released.
Ingredient identity (INCI / CAS), specification sheet and SDS are available for review. Match the documents to your quoted batch before you commit.

Tirzepatide is filled to several vial specifications. The fill amount is the only difference between them — identity, purity and batch documentation come from the same bulk material, so a buyer comparing sizes is comparing packaging, not quality.

| 30mg per vial | Open the 30mg specification |
| 40mg per vial | This page |
| 50mg per vial | Open the 50mg specification |
| 60mg per vial | Open the 60mg specification |
State the required fill amount and vial count at inquiry stage; alternative fill specifications can be quoted as a project.
The 40mg specification is currently documented against bulk batch WM-U7U0-TR. Purity and identity on that certificate were determined on the bulk peptide used for filling; the fill amount is stated against the filling record. Those are two different kinds of evidence and the certificate says so on its face.
| Item | Current batch | Method |
|---|---|---|
| Batch | WM-U7U0-TR | — |
| Purity | 99.33% | RP-HPLC (214 nm) |
| Identity | Conforms | ESI-MS |
| Fill amount | 40 mg/vial | Filling record, not an independent content assay |
The batch certificate can be downloaded from our document centre. Documents for the specific lot you are quoted are issued against that lot — confirm the batch on the certificate matches the batch on the offer before comparing suppliers. Our annotated walkthrough of a batch certificate explains which figures on a COA are specifications, which are measurements, and which are neither.
