Question 1

What are research peptides?

Accepted Answer

Research peptides are short chains of amino acids (typically 2–50 residues) synthesized for in-vitro and in-vivo laboratory research. They are used by scientists to study biological processes, receptor binding, cell signaling, and more. Our peptides are sold strictly for research purposes and are not intended for human consumption.

Question 2

Are your peptides for human use?

Accepted Answer

No. All CertaPeptides products are sold strictly for research and laboratory use only. They are not intended for human consumption, veterinary use, or any clinical application. By purchasing, you confirm that you are a qualified researcher or institution.

Question 3

What purity level do your peptides have?

Accepted Answer

All our peptides are guaranteed ≥98% purity as verified by HPLC (High-Performance Liquid Chromatography) and mass spectrometry. Every batch comes with a Certificate of Analysis (COA) documenting the exact purity, identity confirmation, and any impurity profiles.

Question 4

Do you ship internationally?

Accepted Answer

We currently ship across all 24 EU member states that participate in the SEPA payment network. We offer free shipping on orders over €200. Standard delivery typically takes 5–7 business days, express 3–5 business days depending on your location.

Question 5

What payment methods do you accept?

Accepted Answer

We currently accept SEPA bank transfers via BANKpay+ for instant, secure payments across Europe. This method offers near-zero fees and instant settlement. We are working on adding additional payment options in the near future.

Question 6

How long does shipping take?

Accepted Answer

Standard EU shipping takes 5–7 business days. Express shipping takes 3–5 business days. Orders placed before 2 PM CET on weekdays are typically dispatched the same day. You will receive a tracking number via email once your order ships.

Question 7

Is there free shipping?

Accepted Answer

Yes! We offer free standard shipping on all orders over €200 within the EU. Orders under €200 have a flat standard shipping rate of €7.99, or €24.99 for express delivery.

Question 8

Can I track my order?

Accepted Answer

Yes. Once your order is dispatched, you will receive a tracking number via email. You can also view your order status and tracking information in your account dashboard.

Question 9

What if my order is damaged in transit?

Accepted Answer

If your order arrives damaged, please contact us within 48 hours with photos of the damaged packaging and products. We will arrange a replacement or full refund at no additional cost.

Question 10

Accepted Answer

Orders can be cancelled or modified within 2 hours of placement, provided they haven’t been dispatched yet. Contact our support team immediately if you need to make changes.

Question 11

Do you offer bulk or institutional pricing?

Accepted Answer

Yes. We offer volume discounts for research institutions, universities, and labs ordering in larger quantities. Contact us at support@certapeptides.com with your requirements for a custom quote.

Question 12

What testing do your peptides undergo?

Accepted Answer

Every batch undergoes a rigorous 5-point testing protocol: (1) HPLC purity analysis, (2) Mass spectrometry identity confirmation, (3) Endotoxin LAL testing, (4) Bioburden testing, and (5) Visual inspection and lyophilization quality check. Results are documented in a Certificate of Analysis included with every order.

Question 13

What is a Certificate of Analysis (COA)?

Accepted Answer

A COA is an official document from an independent third-party laboratory that verifies the identity, purity, and quality of a peptide batch. It includes HPLC chromatograms, mass spectra, and detailed test results. Every CertaPeptides order includes the relevant COA.

Question 14

Can I verify a COA batch number?

Accepted Answer

Yes. Every COA has a unique batch number. You can verify the authenticity of your COA by contacting us with the batch number, and we will confirm it against our records.

Question 15

How should I store my peptides?

Accepted Answer

Lyophilized (freeze-dried) peptides should be stored at -20°C for long-term storage or 2–8°C (refrigerator) for short-term use. Reconstituted peptides should always be stored at 2–8°C and used within 2–4 weeks. Keep peptides away from light, heat, and moisture.

Question 16

How do I reconstitute lyophilized peptides?

Accepted Answer

Use bacteriostatic water or sterile water for injection. Add the solvent slowly along the vial wall — do not shake or vortex. Let the peptide dissolve naturally (1–2 minutes). See our Reconstitution Guide at /reconstitution-guide for solvent selection and standard mass-to-volume relationships.

Question 17

What is your return policy?

Accepted Answer

Due to the nature of research chemicals, we cannot accept returns on opened or used products. Unopened products in original sealed packaging may be returned within 14 days of delivery for a full refund, minus shipping costs.
