BPC-157 + TB-500 Blend China Wholesale Guide

Write both component amounts, not only the total

Define BPC-157 identity and nominal content, TB-500 identity and nominal content, component ratio, total content, material form, vial count and RUO status. A label saying 10mg could mean 5mg+5mg or 10mg of each component depending on seller conventions. Require the quotation, specification, COA, analytical files, label and packing list to show every component amount and the total unambiguously. The commercial blend name cannot replace component-level identity, and ratio or component substitutions need explicit buyer approval.

Compare 5+5, 10+10 and 15+15 correctly

Build separate rows for the three configurations, recording each component amount, total per vial, vials, total order quantity of each peptide, ratio tolerance, fill tolerance, incoming component lots, blend lot, finished lot and price basis. A 20mg total vial is not equivalent to two 10mg total vials operationally because filling and packaging controls differ. Ask whether strengths share incoming lots and how genealogy is preserved. Compare cost per documented component, not just total labeled milligrams or kits.

Review incoming component evidence first

Request batch-specific identity, purity and applicable quantitative evidence for every incoming BPC-157 and TB-500 lot used in the blend. Check sample IDs, expected molecular information, chromatograms, mass data, dates, methods, specifications and authorization. Standalone reports help qualify inputs but do not automatically release the finished blend. Map each incoming lot through dispensing, blend batch, fill batch and finished lot. A supplier should retain original component records and explain any retest, relabeling or source change.

Demand finished-blend composition evidence

Ask which methods distinguish the two components, confirm each identity, assess the ratio or individual content and support finished-unit quantity. A single overall HPLC purity number may not establish that both intended peptides are present at the correct amounts. Review blend sample identifiers, complete chromatograms or profiles, quantitative results, specifications and report approval. Require a justified homogeneity or sampling approach and reconcile yield and filled units. Preserve method limitations rather than stretching one result to imply identity, ratio, purity and content simultaneously.

Audit blending, labeling and receiving controls

Identify who dispenses components, performs blending, fills vials, tests the blend and releases finished stock. Ask how line clearance, mixing, homogeneity, yield, rejected units and remaining material are controlled. Approve labels showing both full component names, both amounts, total, lot and RUO wording. Confirm vial, closure, secondary protection, MOQ, released stock and change notification. At receipt, inspect representative labels and seals and quarantine unexplained ratio, total, lot, appearance or document differences until a quality decision is approved.

Build one comparable wholesale RFQ matrix

Send every candidate the same fields: controlled identity, strength, vial count, total material, target purity or composition, identity method, quantitative-content basis, offered lot, testing status, packaging, documents, MOQ, lead time and shipping term. Mark missing answers as exceptions instead of filling gaps with assumptions. Separate testing, setup, customization and transport costs from recurring unit price. A standardized matrix gives scientific, purchasing and quality reviewers one auditable record and prevents an incomplete offer from appearing cheaper simply because it describes less work.

Apply a batch-focused quality-control review

Define every required attribute, acceptance criterion, method and record before purchase. Use the quality-control framework to connect each supplier claim to evidence and its method scope. Check sample identifiers, dates, report numbers, units and lot relationships across the complete reports. Batch-specific evidence is more decision-useful than a representative certificate. Preserve original files, record revisions and investigate contradictions before approving shipment. Where risk warrants, arrange independent testing under a documented sampling and custody plan.

Create a documentation gate before dispatch

List the required batch COA, analytical attachments, SDS, specification, supported storage statement, label proof, invoice and packing list in the RFQ and purchase order. Reconcile product, strength, lot, quantity and revision across records with the documentation guide. Require replacement documents when the offered lot changes. The importer remains responsible for current destination requirements. Research-use wording improves clarity but cannot guarantee customs entry or replace destination-specific legal and broker review.

Verify supplier and batch ownership

Document the legal seller, manufacturing site, analytical laboratory, filling or packaging site, inventory owner, release authority and dispatch entity for the exact SKU. A trading or coordination company can work with qualified partners, but roles and accountability must be transparent. Ask who owns the batch record, authorizes release, handles deviations and provides corrective action. Require advance notification when a critical party changes. Business-registration evidence supports identity but does not replace technical qualification of the offered lot.

Plan logistics and receiving controls

Confirm dispatch location, carrier, shipping term, packaging configuration and realistic production, release and transit windows. Reject guarantees of customs clearance or misleading declarations. On receipt, document package condition, seals, product, strength, lot and quantity, then connect internal inventory to the supplier batch. Store according to the applicable approved specification and quarantine unexplained damage, label conflicts, quantity differences or excursions until a documented quality decision is completed.

Use actual performance for repeat-order approval

A controlled evaluation order should use the same specification and evidence expectations planned for wholesale scale. Assess document accuracy, packaging, delivery time, communication and corrective response. Update a supplier scorecard from observed performance rather than catalog breadth or claims. For every new lot, repeat the batch review and approve current documents before dispatch. Require notification before changes to material specification, manufacturing, testing, filling, labels, packaging or other buyer-approved conditions.
