- Before purchasing research-grade Sermorelin, compare suppliers across verification depth, testing independence, and documentation transparency. The table below contrasts standard industry practice against the verification standard required for reproducible research.
- Standard Peptide Vendor
- HPLC at synthesis (single-point)
- Not conducted. Purity % only
- Not conducted or not documented
- Not conducted
- Batch number and purity % only
- No
- Adequate for preliminary screening; insufficient for publication-grade work
- Research-Grade Supplier (Claimed)
- HPLC at synthesis + post-lyophilization
- HPLC-MS on request (additional fee)
- LAL assay on request (additional fee)
- Not standard
- Full methodology if requested
- Better than standard vendors but verification gaps remain for critical studies
- Real Peptides (2026 Standard)
- HPLC at synthesis + post-lyophilization + quarterly re-testing
- HPLC-MS on every batch (included)
- Chromogenic LAL assay <0.25 EU/mg (included)
- USP <71> bacterial/fungal (included)
- Full COA with test dates, methodology, and accredited lab stamps
- Yes. Quarterly for inventory >90 days
- Meets FDA IND-enabling study requirements; suitable for publication and regulatory submission
- The bottom line: if your research will be published, submitted for regulatory review, or used to inform clinical trial design, single-point purity testing is not sufficient. The best sermorelin supplier third party tested must verify sequence accuracy, endotoxin levels, and sterility through independent laboratories. Not in-house testing by the synthesis facility.
