Get Free Sample in 24 hThe Real‑World Pain Points Stopping Your R&D Progress
1. High Price & Low Quality – Many suppliers quote premium prices for peptides that fail purity tests (<10% of batches meet >95% HPLC purity). This forces labs to repeat syntheses, inflating budgets by 30‑40%.
2. Slow Delivery & Expensive Shipping – Traditional Asian factories often ship in 6‑8 weeks with freight costs exceeding $2,500 per kilogram, delaying critical study milestones.
3. Uncertain Regulatory Compliance – Lack of GMP, DMF, or FDA‑registered facilities makes it risky to import peptides for IND‑enabling studies, exposing companies to audit failures.
4. Limited Customization Options – R&D teams need tailored peptide lengths, isotopic labeling, or specific salt forms. Off‑the‑shelf catalogues rarely accommodate these nuances.

Frequently Asked Questions (FAQ)
What is the typical lead time for a 10 g order of Kappa‑opioid receptor agonist peptide?
Standard production takes 5‑7 business days; with express air freight the total door‑to‑door time is **3‑5 days**.
Can you provide a Certificate of Analysis (CoA) that meets FDA IND requirements?
Yes. Every batch is accompanied by a GMP‑compliant CoA, including HPLC chromatogram, MS spectrum, and residual solvent analysis.
Do you offer custom salt forms or isotopic labeling?
Absolutely. Our OEM service covers TFA, HCl, acetate salts, as well as 13C/15N labeling, with a minimum order of 5 g.
How do you ensure batch‑to‑batch consistency?
We employ continuous‑flow solid‑phase peptide synthesis (SPPS) with in‑process HPLC monitoring; variance stays below 0.5%.
What payment terms are accepted for first‑time buyers?
We accept T/T, PayPal, and Letter of Credit (L/C) for orders >10 g. A 30% upfront deposit secures production.
Is there a free sample program for academic labs?
Yes – we ship up to 5 mg of free, fully‑characterized peptide to verified university labs. Just fill out the short request form.
