Purity vs quantity distinction
Purity (%) and reported quantity are distinct analytical parameters. Review purity and reported quantity separately, and confirm the labeling and assay basis for the batch proposed for your order.

Key Review Snapshot
Start with the review points that shape quotation quality.These checkpoints help buyers align file scope, vial format, packaging, MOQ, lead time, and buyer-side review before comparing supplier offers.
Product FormatLyophilized peptide vial
Supply FocusB2B sourcing and documentation review
DocumentationBatch COA stating RP-HPLC purity and MS identity, plus SDS/MSDS and specification sheet. Karl Fischer water content and counter-ion data are arranged per project where a specification requires them.
Quotation ScopeFill amount, vial count, packaging format, MOQ, and lead time are confirmed together at quotation stage.
PackagingSealed lyophilized vial with stopper and cap. Neutral-label or private-label discussion for qualified projects. Store unopened vials at 2–8 °C as standard, or −20 °C for long-term storage — approximately 24 and 36 months respectively as WUMO product guidance, with the batch COA and product documentation governing. Keep sealed, protected from light and moisture.

Why buyers trust WUMO
Real content, documented — not guesswork
In peptide sourcing, chromatographic purity and delivered quantity require separate evaluation. We keep purity and labeling basis distinct on available documentation, so buyers can review analytical parameters for their quoted batch before ordering.
Batch-specific documents
Batch documentation reflects the specific lot produced. Ask which batch-specific documents are available for the quoted lot, including COA and supporting HPLC or MS records where applicable.
Documented before commitment
Ingredient identity (INCI / CAS), specification sheet, and SDS are available for technical review. Confirm documentation for the batch proposed for your order before purchase.

Nomenclature Clarification
Before sourcing TB-500, procurement and documentation review teams should confirm whether the inquiry refers to TB-500 as a fragment or to a TB-4 specification. WUMO supplies TB-500 as a fragment under this hub. The TB-4 component in WUMO's Glow Blend is separately specified and subject to project confirmation.
What WUMO Can Supply
- TB-500 2mg lyophilized vial fill specification
- TB-500 5mg lyophilized vial fill specification
- Batch-specific COA under documentation review
- Identity verification records
- Quotation unit clarification: USD per gram / vial / box
- Co-formulated vial option — see the BPC-157 + TB-500 vial, where documentation distinguishes the two components
Choosing Between 2mg and 5mg
The two fill specifications differ in vial fill quantity, not fragment identity. Fill choice is driven by downstream packaging plan, quotation unit comparability, and MOQ/lead time planning.

FAQ
Is TB-500 the same as TB-4?
No. The two names refer to different specifications. WUMO supplies TB-500 as a fragment under this hub. Treating the names as interchangeable at inquiry stage can create documentation review issues.
The TB-4 component in WUMO's Glow Blend — is it full-length or fragment?
The TB-4 component in WUMO's Glow Blend is a separately specified component; full-length vs fragment scope is subject to project confirmation.
Why does this page cover both 2mg and 5mg fill specifications?
The two fill specifications differ in vial fill quantity, not in fragment identity. A single hub page lets teams compare fill specifications without duplicate documentation review.
How should procurement teams compare a 2mg vial quote and a 5mg vial quote?
USD per gram or USD per fully built-out packaging configuration produces the most directly comparable view. Per-vial comparison alone can be misleading.
Specification and documentation references
Before requesting a quotation, these guides cover the specification and document questions that come up most often on this product.
- TB-500 fragment sourcing guide — identity fields, document set and RFQ structure.
- TB-500 vs TB-4 nomenclature checks — confirming which material a quote refers to.
- What a 10mg vial actually contains — how peptide content, counterion, moisture and excipients divide up the mass, and what a per-vial claim needs behind it.
- Lyophilized cake appearance and reconstitution — why cakes hold or collapse, what the excipient system does, and what can reasonably be specified.
