Question 1

What are research peptides?

Accepted Answer

Research peptides are short chains of amino acids used exclusively in scientific research and laboratory settings. They are not intended for human consumption. All Pepcore products are sold strictly for research use only (RUO).

Question 2

What is the purity of your peptides?

Accepted Answer

All Pepcore peptides undergo rigorous HPLC testing and are guaranteed at a minimum purity of 99%. A Certificate of Analysis (COA) is available on request, verifying the identity and purity of each product.

Question 3

Do you provide Certificates of Analysis (COA)?

Accepted Answer

Yes. A Certificate of Analysis is available on request. It includes HPLC purity data, mass spectrometry results, and batch information. We do not include a printed COA in every shipment, but just ask via Telegram (@Pepcore) or email and we will share the COA for your batch.

Question 4

What is HPLC testing?

Accepted Answer

HPLC (High-Performance Liquid Chromatography) is the gold standard analytical method for verifying peptide purity. It separates the components of a peptide sample and measures the percentage of the target compound. A result of ≥99% means less than 1% impurities.

Question 5

Are your products for human use?

Accepted Answer

No. All Pepcore products are sold strictly for in-vitro laboratory and research use only (RUO). They are not intended for human consumption, veterinary use, diagnostic, or any clinical application.

Question 6

What is the difference between lyophilized and prepared research material?

Accepted Answer

Lyophilized peptides are freeze-dried powder form. This is how we ship all products. They are stable at room temperature for short periods and at -20°C for long-term storage. Preparation and handling should follow qualified laboratory protocols only.

Question 7

How do I place an order?

Accepted Answer

Browse our catalog, add products to your cart, and proceed to checkout. You can pay with SEPA bank transfer. Orders are confirmed once payment is received.

Question 8

What payment methods do you accept?

Accepted Answer

We accept SEPA bank transfers. All transactions are processed securely. For large or recurring research orders, please contact us for invoicing options.

Question 9

Do you offer bulk or wholesale pricing?

Accepted Answer

Yes, we provide custom quotations for institutional research orders. Please contact us directly at info@pepcore.net with your requirements and we will provide a tailored quote.

Question 10

Is there a minimum order value?

Accepted Answer

There is no minimum order value. However, orders above €250 qualify for free shipping within the EU.

Question 11

How long does EU delivery take?

Accepted Answer

EU delivery typically takes 2–5 business days with tracked shipping. Orders placed before 12:00 CET are dispatched the same business day.

Question 12

Do you offer free shipping?

Accepted Answer

Yes, shipping is free on all orders above €250 within the EU. Orders below €250 incur a flat shipping fee shown at checkout.

Question 13

Do you ship to the Netherlands, Germany, and Belgium?

Accepted Answer

Yes, we ship to all EU countries including the Netherlands, Germany, Belgium, France, Spain, Italy, Austria, and more. Same-day dispatch for orders placed before 12:00 CET.

Question 14

How do I track my order?

Accepted Answer

Once your order is dispatched, you will receive an email with a tracking number and link. You can also track your order status by logging into your account on our website.

Question 15

How is the packaging?

Accepted Answer

All orders are shipped in professional outer packaging that protects product integrity during transit, with standard carrier shipping labels and full tracking. Inner product labels carry compliant research-chemical labelling: product name, batch number, and the "for laboratory research use only" notice.

Question 16

How should I store lyophilized peptides?

Accepted Answer

Lyophilized (freeze-dried) peptides should be stored at -20°C for long-term storage. They can tolerate brief periods at room temperature (e.g., during shipping) without significant degradation. Keep away from direct sunlight and moisture.

Question 17

How long do peptides last in storage?

Accepted Answer

Lyophilized peptides stored at -20°C in sealed vials typically remain stable for 12–24 months. Prepared research material should be handled according to qualified laboratory protocols and the relevant COA guidance.

Question 18

Do you provide handling protocols?

Accepted Answer

No. Pepcore supplies research materials only, with a Certificate of Analysis available on request. Preparation, handling, and analytical protocols must be defined by qualified laboratories and authorized research professionals.

Question 19

Can prepared material be frozen?

Accepted Answer

Storage decisions for prepared laboratory material should follow qualified research protocols, compound-specific stability data, and internal laboratory controls.

Question 20

What is your return policy?

Accepted Answer

Due to the nature of research chemicals, we cannot accept returns on opened products. Unopened products in original packaging may be returned within 14 days of delivery. Please contact support for return authorization.

Question 21

What if my order arrives damaged?

Accepted Answer

If your order arrives damaged, contact us immediately via Telegram (@Pepcore) or email with photos of the damage. We will arrange a replacement or refund at no extra cost.
