Research Peptides FAQ

Use bacteriostatic water or sterile water, then inject it gently down the vial wall. Next, swirl slowly instead of shaking so you protect peptide integrity. Finally, choose a solvent volume that matches your target concentration.

Store unopened lyophilized vials in a cool, dry place and keep them away from light and moisture. For long-term storage, use refrigeration (2–8°C). For extended storage, freezing at -20°C often works best.

After reconstitution, keep the vial refrigerated and use it within a few weeks whenever possible. Because stability varies by peptide, treat storage guidance as general rather than absolute. If you need a batch-specific note, contact our support team via Contact.

Many researchers choose bacteriostatic water because it helps reduce contamination risk after multiple withdrawals. However, some protocols require sterile water or another solvent. Therefore, follow your method and review the product documentation for compatibility.

We manufacture peptides to a minimum purity of 98%, and many batches reach 99%+. Additionally, we confirm purity with HPLC so you can evaluate batch consistency.

Yes. We provide a COA upon request, and we can include key analytical results such as HPLC and mass spectrometry. Consequently, you can document materials within your lab’s QA process. For help, use our contact form.

We primarily use HPLC to separate compounds and quantify purity. We also use mass spectrometry to confirm molecular identity. For background reading, visit the NCBI.

We run endotoxin testing using standard methods (such as LAL where applicable), and we document results where required. As a result, researchers can evaluate suitability for controlled laboratory workflows.

We ship to many regions, and we highlight restrictions when local rules apply. Therefore, check your destination requirements before you place an order.

We seal vials, protect them from light, and pack them securely to reduce transit risk. When temperature sensitivity matters, we also add cold packs. In addition, we keep packaging discreet.

UK deliveries often arrive within a few business days, while international timelines vary. Because customs processing can change delivery times, consider that factor for time-sensitive work.

We accept major cards and other available checkout options shown at purchase. Additionally, we secure payments through encrypted processing to protect your data.

Contact us quickly after purchase if you need changes. If the order enters processing, we may not be able to modify it. Therefore, submit changes promptly via Contact Us.

Yes. We discuss volume pricing case-by-case for institutions and repeat orders. Consequently, email us with requirements so we can prepare accurate options.

Laws vary by jurisdiction, so you should confirm local requirements before purchase. However, many regions allow purchase for legitimate research. For policy questions, visit our About Us page and then contact support if needed.

“Research Use Only” means you must use products strictly for laboratory research. We do not market products for human or veterinary use. Therefore, you should not request guidance outside research contexts.

No. Use products only for laboratory research. Additionally, follow your institution’s compliance policies at all times.
