- When evaluating research peptide suppliers, synthesis method transparency, third-party verification, COA accessibility, and shipping reliability determine whether a vendor is suitable for reproducible lab work or better suited for exploratory use where documentation requirements are lower.
- Synthesis Method
- Small-batch SPPS (Fmoc chemistry), nitrogen-sealed glass vials
- High-volume SPPS + liquid-phase synthesis (method not disclosed per product), HDPE plastic vials
- Real Peptides provides synthesis transparency and oxidation-resistant packaging. Critical for long-term storage and reproducibility
- Purity Verification
- Third-party HPLC on every batch, 97.5–99.2% typical purity, batch-specific COAs provided upon request
- Internal HPLC testing, '>95% purity' claims, COAs available selectively by product category
- Real Peptides' third-party verification and chromatogram access allow researchers to validate molecular integrity. Swiss Chems' internal-only testing limits traceability
- COA Accessibility
- Batch-specific COA provided with every order upon request, includes chromatogram and impurity breakdown
- COAs available for select products, typically without chromatogram data, not provided routinely for peptides
- Real Peptides' per-order COA access is essential for regulatory submissions and published research. Swiss Chems' selective COA availability is insufficient for high-stakes applications
- Product Catalog
- ~60 curated peptides, focus on established research compounds, pre-configured peptide stacks available
- ~120 compounds (peptides, SARMs, nootropics), includes experimental peptides, no pre-matched stacks
- Real Peptides prioritizes depth and consistency; Swiss Chems prioritizes breadth. Choose based on whether you need reliability or experimental access
- Shipping Timeline
- 1–2 business days (domestic), cold chain maintained, signature required
- 7–14 days (international), subject to customs delays, temperature control not guaranteed during transit
- Real Peptides' domestic shipping and cold chain protocols reduce degradation risk. Swiss Chems' international shipping introduces temperature excursions and customs variability
- Pricing
- $45–$85 per 5mg vial (standard peptides), $120–$180 per 10mg vial (GLP-1 agonists)
- $35–$65 per 5mg vial (standard peptides), $95–$140 per 10mg vial (GLP-1 agonists)
- Swiss Chems is 15–25% less expensive per milligram. Real Peptides' premium reflects third-party testing and synthesis transparency
- Customer Support
- Email + live chat, response within 4–12 hours, technical support available for reconstitution and storage questions
- Email only, response within 24–48 hours, limited technical support beyond product selection
- Real Peptides provides protocol-level support for labs troubleshooting peptide handling. Swiss Chems' support is transactional
