How it compares
TB-4 Sources: Research Suppliers vs. Unlicensed Vendors vs. Real Peptides
San Francisco researchers looking to buy TB-4 face three supplier categories: institutional research suppliers (high purity, institutional pricing, minimum order volumes), unlicensed overseas vendors (inconsistent purity, no verifiable COA, customs risk), and direct-to-consumer verified suppliers like Real Peptides. Here's the honest answer: institutional suppliers are designed for labs with purchase orders and budget approvals. Not individuals. Overseas vendors offer lower prices but introduce chain-of-custody risk that makes published research unreproducible. Real Peptides bridges the gap: research-grade purity with individual-friendly pricing and US-based fulfillment that eliminates customs delays.
| Supplier Type | Purity Verification | Shipping to SF | Individual Orders | Professional Assessment |
|---|---|---|---|---|
| Institutional Suppliers | Full COA, batch traceability | 5–10 business days | Minimum $500+ orders | Best for labs, not individuals |
| Overseas Vendors | Self-reported, inconsistent | 10–21 days + customs | Yes, low minimums | High variability, customs risk |
| Real Peptides | Third-party HPLC + MS | 24–48 hours | Yes, no minimum | Verified quality, individual access |
| Local Resellers | Rare, often repackaged | Variable | Limited availability | Markup without added value |

Questions
Real Peptides sells research-grade TB-4 directly to individuals in San Francisco without requiring institutional affiliation or credentials. Simply place an order through our online platform, and we ship to any California residential or commercial address with full COA documentation. All peptides are labeled for research purposes only and comply with California state regulations governing non-therapeutic peptide sales.
Every batch of TB-4 sold to San Francisco customers tests at >98% purity via third-party HPLC and mass spectrometry analysis. The Certificate of Analysis accompanying your order shows the exact purity percentage, synthesis date, and batch number. We do not sell peptides below 97% purity, and most batches test between 98.5% and 99.2%.
Real Peptides operates as an online-only supplier with US-based fulfillment. We do not maintain walk-in locations in San Francisco or offer local pickup. However, our 24–48 hour shipping to Bay Area zip codes is faster than most local suppliers can fulfill custom orders, and you receive verified COA documentation that local resellers typically cannot provide.
California law permits the sale and possession of research peptides like TB-4 when labeled for non-therapeutic, research-only use. Real Peptides complies with all state labeling and documentation requirements, and we do not sell peptides for human consumption or therapeutic application. Buyers must be 18 or older, and all products are intended for in vitro research.
TB-4 (thymosin beta-4) is the naturally occurring 43-amino-acid peptide; TB-500 is a synthetic fragment (amino acids 1–4 or the full sequence depending on supplier terminology) used interchangeably in most research contexts. Real Peptides uses 'TB-500' as the product name for full-sequence thymosin beta-4 to align with common research nomenclature. The peptide you receive is the complete 43-amino-acid thymosin beta-4 chain, verified via mass spec.
Lyophilized (powder) TB-4 remains stable at room temperature for up to 30 days but should be refrigerated (2–8°C) for long-term storage beyond that window. Once reconstituted with bacteriostatic water, store the solution in a refrigerator and use within 28 days. San Francisco's mild climate rarely causes stability issues during shipping, but avoid leaving packages in direct sunlight or hot vehicles after delivery.
Yes. San Francisco researchers frequently order TB-4 alongside BPC-157, GHK-CU, and other healing-focused peptides in our pre-configured bundles. The Healing Total Recovery Bundle includes TB-4, BPC-157, and supporting compounds with dosing protocols designed for tissue repair research models.
