- The table below compares Real Peptides NAD+ to three common competitor categories based on verifiable quality metrics. Not marketing claims.
- Third-Party HPLC Verification
- Yes. ISO 17025 lab, batch-specific
- Sometimes. Varies by supplier
- Rarely. COA often from manufacturer
- No. Not required for supplements
- Real Peptides provides independently verified purity for every batch; competitors rely on self-reported or supplier-provided certificates
- Batch Traceability
- Full. Unique batch number with test report access
- Limited. Generic COA without batch linkage
- None. Bulk lots with no individual tracking
- None. Supplements lack batch documentation
- Only Real Peptides links every vial to specific test data; untraceable batches make protocol troubleshooting impossible
- cGMP Synthesis
- Yes. Validated process controls, contamination limits
- Inconsistent. Many lack cGMP certification
- No. Synthesized in non-regulated facilities
- No. Dietary supplements follow different standards
- cGMP ensures environmental controls and process validation; non-cGMP peptides introduce uncontrolled contamination risk
- Endotoxin Testing (LAL Assay)
- Yes. <10 EU/mg verified per batch
- Rarely. Not standard for research peptides
- No. Untested
- No. Not applicable to oral supplements
- Endotoxin contamination causes inflammatory responses in cell culture and animal models; Real Peptides tests every batch to eliminate this variable
- Sterility Verification (USP <71>)
- Yes. Sterile filtration and culture testing
- Sometimes. Depends on intended use
- No. Sterility not guaranteed
- No. Oral products not sterile
- Real Peptides NAD+ is sterile-filtered and culture-tested; non-sterile peptides risk microbial contamination in sensitive protocols
- Typical Purity Range
- 99.0–99.8% (HPLC verified)
- 95–98% (claimed, often unverified)
- 85–95% (variable, untested degradation)
- 60–90% (ConsumerLab found failures)
- Real Peptides consistently delivers 99%+ purity; competitors show batch-to-batch variation and unverified claims
