When you’re sourcing Gastrin 17 (Gastrin I) peptide for in‑vitro or in‑vivo studies, three critical issues often derail timelines and budgets:
- High Unit Cost – Many suppliers quote prices that exceed $1,200 / g for GMP‑grade material, inflating research budgets by up to 30 %.
- Variable Purity & Bioactivity – Inconsistent HPLC purity (often <95 % ± 2 %) leads to assay failure, requiring repeat experiments and extending project cycles.
- Slow Lead Times & Expensive Shipping – Typical delivery windows of 4‑6 weeks plus $250+ freight create bottlenecks, especially for time‑sensitive clinical‑grade batches.
- Regulatory Uncertainty – Lack of documented GMP, ISO‑9001, or FDA compliance can jeopardize IND submissions and audit readiness.
- Limited Customization – Bulk orders often lack the flexibility for custom peptide lengths, isotopic labeling, or specific salt forms required for niche assays.
Imagine a scenario where your next pre‑clinical study is delayed because the peptide batch failed purity testing, costing you $15,000 in labor and reagents. That risk is avoidable.

Application Scenarios & Case Studies
Case Study 1 – Oncology Biomarker Validation (USA)
Acme Biotech needed 5 g of GMP‑grade Gastrin‑17 for a GLP‑compliant assay. Our 7‑day delivery saved them 12 weeks compared with their previous vendor, cutting total project cost by $22,000. The assay passed FDA pre‑IND review on the first submission.
Case Study 2 – Academic Gastro‑Enterology Research (UK)
University of Cambridge ordered 250 mg of isotopically‑labeled Gastrin‑17 for mass‑spectrometry mapping. We provided custom ^13C‑labeled peptide within 48 hours, enabling the team to publish in Nature Communications ahead of schedule.
Frequently Asked Questions
What is the typical MOQ for Gastrin‑17 (CAS 81123‑06‑0)?
The minimum order quantity (MOQ) is **1 g** for research‑grade and **5 g** for GMP‑grade. Larger bulk orders (up to 1 kg) are available with volume discount.
Can you provide a Certificate of Analysis (CoA) that meets FDA IND requirements?
Yes. Every GMP batch is accompanied by a full CoA, including HPLC chromatogram, MALDI‑TOF, endotoxin, and residual solvent data, all signed by our QA manager.
Do you offer custom salt forms or isotopic labeling?
Absolutely. Our OEM/ODM team can deliver TFA, HCl, acetate salts, or ^13C/^15N‑labeled variants. Lead time for custom work is typically 10‑14 days.
What shipping options are available for the USA?
We provide DDP (Delivered Duty Paid) air‑freight to all major US ports, express courier (UPS/DHL) for <48‑hour urgent shipments, and sea freight for bulk (>10 kg) orders.
