- HPLC Purity Analysis
- Purity ≥95%, single dominant peak at correct retention time, batch-specific CoA from ISO 17025 lab
- Purity <80%, multiple contaminant peaks, generic or missing CoA, refusal to provide batch testing
- 3–5 business days
- Gold standard. Only method that quantifies active peptide concentration and identifies specific adulterants
- Mass Spectrometry (MS)
- Molecular weight 1075.2 Da ±0.5 Da, fragmentation pattern matches acetyl octapeptide-3 sequence
- Incorrect molecular weight, fragmentation inconsistent with 8-residue sequence, presence of unidentified compounds
- Confirms peptide identity at molecular level. Eliminates possibility of substituted or truncated analogs
- Supplier GMP Certification
- FDA-registered facility, transparent batch traceability, published CoAs for every lot, accessible technical support
- No regulatory registration, vague sourcing claims, generic CoAs not linked to batch numbers, offshore address with no verification
- Immediate (document review)
- Strong correlation with product quality. GMP compliance requires documented processes that counterfeit operations cannot replicate
- Price Comparison
- Within 15% of industry average for research-grade peptides, pricing stable across batches
- 40–60% below market rate, unexplained discounts, prices fluctuate dramatically between orders
- Immediate
- Significant underpricing reliably predicts reduced purity or substituted compounds. Synthesis costs are fixed industry-wide
- Visual/Solubility Test
- White to off-white powder, complete dissolution in sterile water within 3 minutes, clear colorless solution
- Clumping, discoloration, incomplete dissolution, cloudiness, unusual odor
- 5 minutes
- Preliminary screening only. Cannot confirm peptide identity or purity, many fillers exhibit identical physical properties
