TB-500 cost and pricing
TB-500 pricing varies dramatically by source, purity, and dispensing channel. Research-grade TB-500 peptide for sale through chemical suppliers runs $30–80 per 5 mg vial. Compounding pharmacy TB-500 (when available) costs $80–250 per vial depending on dose and preparation. Clinic-administered protocols can exceed $500/month including consultation and monitoring. Here is the full pricing landscape, cost-per-cycle math at standard dosing, and what to evaluate when you decide where to buy TB-500.
Key takeaways
- Research-grade TB-500: $30–80 per 5 mg vial from research peptide suppliers. Quality and purity vary significantly between suppliers.
- Compounding pharmacy: $80–250 per vial (when available through prescriber). Higher cost reflects pharmaceutical-grade manufacturing, third-party testing, and regulatory compliance.
- Clinic protocols: $300–800/month including the peptide, medical consultation, and monitoring. Significant markup over raw peptide cost.
- Cost per 8-week cycle at standard dosing (5 mg/week loading, 2.5 mg/week maintenance): approximately $150–300 from research suppliers, $400–1,000 from compounding pharmacies.
- TB-500 is currently in regulatory transition — compounding pharmacy availability depends on the July 2026 PCAC Category 1 review.
TB-500 pricing by source
| Source type | Price per 5 mg | Purity | Testing | Availability |
|---|---|---|---|---|
| Research peptide supplier | $30–80 | Varies (95–99%+) | CoA, optional HPLC/MS | Generally available |
| Premium research supplier | $60–120 | 99%+ verified | Third-party HPLC + mass spec | Generally available |
| 503A compounding pharmacy | $80–250 | USP-grade | Potency, sterility, endotoxin | Requires prescription; pending Cat 1 |
| 503B outsourcing facility | $120–300 | cGMP | Full batch testing | Requires prescriber; pending Cat 1 |
| Peptide therapy clinic | $200–500 (bundled) | Pharmacy-sourced | Clinic-verified | Consultation + monitoring included |
Cost per cycle
The practical question for most people evaluating the TB-500 price is not the per-vial cost but the total cost of a complete healing cycle:
| Protocol | Vials needed (5 mg) | Research-grade cost | Pharmacy cost |
|---|---|---|---|
| Moderate 8-week (5 mg/wk loading × 4, 2.5 mg/wk maint × 4) | 6 vials | $180–480 | $480–1,500 |
| Aggressive 8-week (10 mg/wk loading × 4, 5 mg/wk maint × 4) | 12 vials | $360–960 | $960–3,000 |
| BPC-157 stack 8-week (TB-500 + BPC-157) | 6 TB + 4 BPC vials | $300–700 | $800–2,500 |
Where to buy TB-500: what to evaluate
If you search “buy TB-500 peptide” or “TB-500 for sale” or “buy thymosin beta 4,” you’ll find dozens of research peptide suppliers with varying price points, quality standards, and legitimacy. Key evaluation criteria when considering where to buy TB-500:
Certificate of Analysis (CoA): Every legitimate peptide supplier provides a CoA with each product showing purity (HPLC), identity (mass spectrometry), and appearance. Suppliers who don’t provide batch-specific CoAs should be avoided.
Third-party testing: The best suppliers use independent third-party laboratories (not in-house) for purity and identity verification. Third-party HPLC and mass spec confirmation is the standard for premium research-grade peptides.
Purity threshold: Look for ≥98% purity on the HPLC analysis. Peptides below 95% purity may contain synthesis byproducts, truncated sequences, or degradation products that reduce efficacy and increase side effect risk.
Storage and shipping: Lyophilized TB-500 is relatively stable, but suppliers should ship with cold packs or expedited shipping in warm weather. Reconstituted TB-500 must be refrigerated and should never be shipped pre-reconstituted.
Regulatory compliance: Research peptide suppliers sell products labeled “for research purposes only” or “not for human consumption.” This labeling is a regulatory requirement for non-pharmaceutical peptide sales and does not inherently indicate quality issues. Compounding pharmacy sources require a prescription and provide pharmaceutical-grade product with full regulatory compliance. As the regulatory landscape evolves post-Category-2-removal, compounding pharmacy availability for TB-500 may expand pending the July 2026 PCAC decision.
For Thymosin Beta-4 for sale — note that full-length Tβ4 (43 amino acids) is significantly more expensive to synthesize than the TB-500 fragment (7 amino acids). Products labeled “Thymosin Beta-4” at prices comparable to TB-500 should be verified carefully — they may actually contain the TB-500 fragment rather than the full-length protein.
Frequently asked questions
How much does TB-500 cost?
TB-500 costs $30–80 per 5 mg vial from research peptide suppliers, $80–250 from compounding pharmacies, and $200–500+ as part of clinic-administered protocols. A complete 8-week cycle at standard dosing costs approximately $180–480 from research sources.
Where is the best place to buy TB-500?
The best place to buy TB-500 depends on your priorities: research peptide suppliers offer the lowest cost, premium research suppliers offer verified purity at moderate cost, and compounding pharmacies (when available with prescription) offer pharmaceutical-grade quality at the highest cost. Evaluate suppliers based on third-party CoA availability, purity (≥98%), and reputation.
Can you buy TB-500 online?
TB-500 is widely available from online research peptide suppliers. Products are sold as research chemicals. Compounding pharmacy TB-500 requires a prescription from a licensed prescriber — availability depends on current FDA regulatory status and PCAC Category 1 review outcomes.
