Independent purity, identity, endotoxin, and contaminant testing for over 85 research and pharmaceutical peptides. Canadian lab, mail-in samples accepted nationwide.
We test over 85 research and pharmaceutical peptides including GLP-1 agonists (semaglutide, tirzepatide, retatrutide), growth hormone peptides (BPC-157, TB-500, tesamorelin, ipamorelin), melanocortin peptides (PT-141, melanotan II), and many others. Every test uses validated HPLC and mass spectrometry methods with a Certificate of Analysis delivered within 9–11 business days.
GLP-1 receptor agonist used in research on metabolic syndrome and type 2 diabetes. HPLC purity and ESI-MS identity essential for batch verification.
Dual GLP-1/GIP agonist. Complex 39-amino acid peptide requiring high-resolution LC-MS/MS for accurate identity confirmation.
Triple GIP/GLP-1/glucagon agonist. Structural complexity requires full MS/MS sequencing for definitive identity confirmation.
15-amino acid peptide used in musculoskeletal and gut research. Frequently adulterated; third-party identity testing strongly recommended.
43-amino acid peptide. HPLC purity and ESI-MS identity critical for research-grade quality assurance.
GHRH analogue. Full HPLC purity, identity by MS, and endotoxin testing available for compounding pharmacy and research applications.
Growth hormone secretagogues frequently sold in combination. Individual identity confirmation by mass spectrometry available.
Melanocortin receptor agonist. HPLC purity and ESI-MS testing available with standard turnaround.
Tetrapeptide. Short sequence requires precise HPLC and MS methods to distinguish from related peptides.
Nootropic peptides of Russian origin. Identity confirmation particularly valuable given supply chain variability.
Long R3 insulin-like growth factor. Large peptide (83 aa) requiring specialized LC-MS/MS analysis protocol.
Delta-sleep-inducing peptide and nicotinamide adenine dinucleotide. Both testable for identity and purity with standard methods.
| Peptide Category | Recommended Tests | Typical Sample | Turnaround |

| GLP-1 / GIP agonists | HPLC purity + ESI-MS identity | 1–2 mg | 9–11 days |
| Growth / repair peptides | HPLC purity + ESI-MS identity | 0.5–1 mg | 9–11 days |
| Injectable peptides | Purity + identity + endotoxin (LAL) | 2–5 mg | 9–11 days |
| Compounding pharmacy batches | Full panel: purity, MS, LAL, ICP-MS | 5–20 mg | 9–11 days |
| Novel / custom sequences | Custom protocol (contact us) | Varies | TBD |
We test peptides beyond our standard list. If your peptide is not shown above, contact us with the sequence, molecular weight, and your testing requirements. We can develop a custom method or adapt an existing protocol in most cases.
