TB-500 is handled as a repair peptides catalog material with sourcing review built around sequence or identity confirmation, repair-category SKU planning, and blend feasibility. Procurement teams should confirm CAS 885340-08-9, formula C38H68N10O14, 889 Da molecular weight, sku coverage includes 2mg*10vials · 5mg*10vials, ≥99%, lead time, and the available COA/HPLC/MS/SDS packet before comparing suppliers or approving a quote.

Buyer fit

Who buys this, and why

TB-500 is listed for qualified B2B buyers reviewing repair-category peptide sourcing and component-document review. Procurement teams should compare sequence identity, repair-category literature context, blend feasibility, and batch-file readiness while keeping the page focused on research-material sourcing rather than personal-use, dosing, treatment, or outcome guidance.

Category: Repair Peptides. Repair-focused peptides and blends for soft-tissue, tendon, GI mucosa, and recovery research.

Quick sourcing answer

Identity
CAS 885340-08-9; PubChem CID 62707662 lists TB-500 / TB500 with formula C38H68N10O14, molecular weight 889.0, and sequence synonym Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln-OH.
Procurement fit
Built for repair-category distributors, research labs, and OEM buyers comparing standalone TB-500, BPC-157, blend feasibility, and repeat-batch document continuity.
Document review
Request current COA, HPLC chromatogram, MS identity support, SDS, storage notes, fragment/sequence context, salt or counter-ion notes when disclosed, and batch-specific label details.
SKU planning
Active catalog coverage includes 2 mg and 5 mg x 10-vial options; 10 mg requests should be handled as separate availability or custom quote review.

Procurement checks

  • Confirm CAS 885340-08-9, formula C38H68N10O14, sequence or fragment context, molecular-weight reference, and current batch availability.
  • Compare 2 mg and 5 mg x 10-vial standalone SKUs against BPC-157 or repair-blend sourcing needs.
  • Request COA, HPLC, MS, SDS, storage notes, counter-ion or salt context when disclosed, and label details before scaling order size.
  • Clarify target quantity, document needs, naming convention, and repeat-order plan for distributor, blend, or OEM review.

Buyer comparison notes

Compared with BPC-157
Supplier comparison should focus on sequence identity, document packet, vial sizes, lead time, blend feasibility, and repeat-order document continuity.
Blend review
For repair-oriented blends, buyers should verify component names, target fill, ingredient ratio, purity support, and label workflow.
Naming control
TB-500, TB500, fragment, and full-length thymosin beta-4 references should be separated before quote approval.

Technical procurement review

Fragment identity and public-reference context

TB-500 should be reviewed as a short thymosin beta-4 fragment identity record rather than the full-length thymosin beta-4 protein. Public PubChem data for CID 62707662 identifies CAS 885340-08-9, formula C38H68N10O14, molecular weight 889.0, and sequence synonym Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln-OH. Full-length thymosin beta-4 / Timbetasin records, such as PubChem CID 16132341, are useful comparison references but should not be treated as the same purchasing entity.

What buyers should compare before quote approval

A useful TB-500 sourcing review connects fragment identity, documents, and commercial terms. Compare CAS 885340-08-9, sequence or fragment support, purity basis, vial size, net peptide content, HPLC purity, MS identity, residual-solvent or counter-ion notes when available, storage guidance, MOQ, lead time, and whether the supplier can repeat the same document standard for reorders.

TB-500 vs BPC-157 and repair-blend sourcing angle

TB-500 and BPC-157 are often compared in repair-category sourcing, but procurement teams should keep component identity separate. A standalone TB-500 quote should be reviewed by CAS, fragment sequence, SKU, purity file, and batch label. Blend or OEM requests require component-level review so the buyer can confirm total fill, ingredient ratio, and whether each component has matching COA/HPLC/MS support.

Standalone, fragment, and full-length naming control

TB-500, TB500, TB-500 Fragment, and thymosin beta-4 can appear together in public searches. Buyer records should state which entity is being quoted and whether the requirement is a standard 2 mg or 5 mg catalog SKU, a repair blend, or a custom fill. Clear naming control helps prevent mismatched COA files, incorrect label copy, and reorder confusion.
