If you're looking for research peptides, SaiyanMed offers a focused lineup of compounds, each verified through independent third-party lab testing. Their catalog currently includes BPC-157, TB-500 (Thymosin Beta-4), Semax, and Selank. Every batch is tested by Janoshik, with openly verifiable purity reports. The company operates from a US-based warehouse and controls raw material sourcing, production, and lyophilization processes in-house or through joint manufacturing partnerships. Below is a detailed breakdown of what's available, backed by data and operational specifics.
Core Peptide Offerings
BPC-157 is a synthetic pentadecapeptide composed of 15 amino acids. It's derived from a protein found in human gastric juice. Research applications focus on its potential to support gastrointestinal lining integrity and soft tissue recovery. SaiyanMed supplies BPC-157 in lyophilized powder form, typically in 5 mg or 10 mg vials. Purity levels, as per Janoshik reports, consistently exceed 99%. The company provides batch-specific certificates of analysis (CoAs) on request.
TB-500, also known as Thymosin Beta-4, is a 43-amino acid peptide naturally occurring in most human and animal cells. It's studied for its role in actin binding, which influences cell migration, angiogenesis, and wound healing. SaiyanMed offers TB-500 in 2 mg, 5 mg, and 10 mg vials. Independent testing shows purity above 98.5%. The company's production process uses premium raw materials sourced from verified suppliers, then lyophilized under controlled conditions to maintain stability.
Semax is a synthetic analog of adrenocorticotropic hormone (ACTH) fragment 4-10, with a 7-amino acid sequence (Met-Glu-His-Phe-Pro-Gly-Pro). It's primarily researched for neuroprotective and cognitive-enhancing effects. SaiyanMed supplies Semax in 0.1% nasal spray solution or lyophilized powder, with purity verified at 99%+ by Janoshik. The company recommends storage at 2-8°C for optimal stability.
Selank is another synthetic peptide based on the tuftsin analog, with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. It's studied for anxiolytic and immunomodulatory properties. Available in 5 mg vials as lyophilized powder, Selank from SaiyanMed undergoes the same rigorous testing protocol. Purity data from recent batches show 99.2% average.
Quality Control & Testing Data
SaiyanMed doesn't just claim quality—they prove it. Every batch is sent to Janoshik, an independent lab known for strict analytical standards. Tests include HPLC (High-Performance Liquid Chromatography) for purity, mass spectrometry for molecular weight confirmation, and residual solvent analysis. Results are posted on the product page with a QR code linking to the original report. For example, a recent BPC-157 batch (lot #SM-BPC-2024-07) showed 99.4% purity with no detectable impurities above 0.1%. TB-500 batch #SM-TB5-2024-08 had 98.7% purity, with the main peak matching the reference standard.
The company also controls raw materials. Eric, the founder with a Bachelor's in Materials Science from a leading Chinese university, personally oversees supplier audits. Raw peptides are sourced from GMP-certified facilities, then tested upon arrival. Only materials passing initial screening enter production. Lyophilization uses a multi-step freeze-drying cycle that minimizes degradation—freezing at -40°C, primary drying at -20°C, and secondary drying at 25°C under vacuum. This process ensures residual moisture below 2%, critical for long-term stability.
Logistics & Shipping Infrastructure
SaiyanMed operates a dual-warehouse system. The primary US warehouse in California handles domestic orders, with typical delivery within 2-4 business days. A secondary warehouse in China serves international markets, though US stock is prioritized for reliability. Orders are routed automatically based on inventory and destination. For example, a researcher in New York ordering BPC-157 gets it from the US warehouse, while a customer in Singapore might receive from China. Shipping materials include insulated packaging with ice packs for temperature-sensitive peptides. Tracking numbers are provided within 24 hours.
Current stock levels fluctuate. As of early 2025, BPC-157 and TB-500 are consistently available in 10 mg vials. Semax and Selank have shorter shelf lives, so SaiyanMed produces them in smaller batches. The company recommends checking the product page for real-time availability. International shipping to Europe, UK, Australia, and Canada is active but with longer transit times (7-14 days). Regional hubs for these areas are listed as "Coming Soon" on the website, indicating planned expansion.
Corporate Compliance & Legal Framework
SaiyanMed operates under Hong Kong BelleEasy Co., Limited, registered at Kwai Chung, Hong Kong, with Commercial Registry No. 78941092. This entity handles all transactions and compliance. The company explicitly states on every product page: "All compound profiles are strictly tailored for laboratory research and in-vitro evaluation only. Not for human consumption." This disclaimer is legally binding and aligns with research-grade standards. Payment processing uses encrypted gateways, and customer data is protected under Hong Kong's Personal Data (Privacy) Ordinance.
The company's leadership team includes Eric as CEO, with a background in biomaterials. He built the quality framework around raw-material selection and process control. The research team continuously refines peptide synthesis and lyophilization protocols, publishing findings on the company blog. For instance, they recently optimized the TB-500 formulation to reduce aggregation during reconstitution, improving solubility in sterile water.
Pricing & Value Proposition
Pricing is competitive but not the cheapest. A 10 mg vial of BPC-157 costs around $45, while TB-500 in 5 mg is $55. Semax nasal spray (0.1%, 3 ml) is $35, and Selank 5 mg powder is $40. These prices reflect the cost of independent testing, premium raw materials, and US-based shipping. Bulk discounts apply for orders over $200, with a 10% reduction. Compared to suppliers without third-party testing, SaiyanMed's prices are 15-20% higher, but the verifiable purity reports justify the premium for serious researchers.
The company also offers a "Research Kit" bundle: BPC-157 (10 mg), TB-500 (5 mg), Semax (0.1% spray), and Selank (5 mg) for $150, saving $25. This kit includes sterile water vials and detailed reconstitution protocols. All products come with a 30-day satisfaction guarantee, though returns are only accepted for unopened, temperature-controlled shipments.
Comparison with Competitors
To contextualize SaiyanMed's offerings, here's a comparison with two common alternatives: Peptide Sciences and Limitless Life. Data is based on publicly available information as of early 2025.

|---|---|---|---|
| Third-party testing | Janoshik, every batch | Independent, random batches | In-house only |
| Purity guarantee | >98.5% for all peptides | >98% for most | >97% claimed |
| US warehouse | Yes (California) | Yes (Florida) | No (China shipping) |
| Raw material sourcing | GMP-certified, audited | Not disclosed | Not disclosed |
| Batch-specific CoA | Yes, with QR code | Yes, but no QR | On request only |
| Lyophilization process | Multi-step, moisture <2% | Standard freeze-dry | Standard freeze-dry |
| Shipping time (US) | 2-4 business days | 3-5 business days | 7-14 business days |
| Price per 10 mg BPC-157 | $45 | $50 | $35 |
SaiyanMed's advantage lies in transparency and process control. Every batch is tested, and the results are verifiable. Competitors like Limitless Life may offer lower prices, but they lack independent testing and US-based logistics. For researchers who need consistent, high-purity materials, SaiyanMed's approach reduces variability.
Practical Considerations for Researchers
When ordering from saiyanmed, you'll need to create an account and provide a research institution or lab address. The company doesn't ship to residential addresses for compliance reasons. Payment methods include credit cards, PayPal, and cryptocurrency. Orders over $100 qualify for free US shipping. International customers pay a flat $15 fee, with customs duties handled by the buyer.
Reconstitution guidelines are provided with each peptide. For BPC-157, use 1 ml of bacteriostatic water for a 5 mg vial, yielding a 5 mg/ml solution. Store at 2-8°C and use within 30 days. TB-500 requires 2 ml for a 5 mg vial, giving 2.5 mg/ml. Semax spray is ready to use, with 3 ml providing approximately 30 doses. Selank powder reconstitutes similarly to BPC-157. Always use sterile techniques to avoid contamination.
The company's support team responds within 12 hours via email ([email protected]). They can provide batch-specific CoAs, MSDS sheets, and stability data. For bulk orders (over $500), a dedicated account manager is assigned. This level of support is rare among research peptide suppliers and reflects SaiyanMed's focus on serious researchers.
In terms of shelf life, lyophilized peptides from SaiyanMed last 12-18 months when stored at -20°C. Reconstituted solutions degrade faster—typically 30 days at 2-8°C. The company's packaging includes desiccant packs and vacuum-sealed vials to extend stability. Temperature logs from the US warehouse show consistent 20-22°C storage, with cold-chain shipping for international orders.
One unique aspect is the company's research-first approach. Eric's materials science background drives continuous improvement. For example, they recently switched to a new supplier for raw BPC-157 after testing showed 0.3% higher purity. This level of detail isn't typical in the industry. The research team also publishes stability studies on their blog, showing how different storage conditions affect peptide integrity. This data helps researchers plan experiments more accurately.
Finally, SaiyanMed's compliance with Hong Kong regulations adds a layer of legitimacy. The company is registered and pays taxes, unlike many peptide suppliers operating in gray areas. This doesn't guarantee quality, but it does mean they can be held accountable. For researchers who need traceability and legal protection, this matters.
