FAQ

We ship from our warehouses in the EU and UK 

It’s important to familiarize yourself with your country’s customs regulations before placing an order. Customs procedures vary significantly between countries, and we cannot be responsible for knowing the rules for each jurisdiction. We strongly advise researching your country’s laws and regulations, as our research chemicals and peptides may not be legal in every country. By placing an order with Research Peptides Europe, you assume full responsibility for ensuring compliance with all applicable laws and customs regulations in your country.

Please also note that we do not accept returns of any kind, including returns due to customs issues. Once a package is returned to us, we cannot restock the items, and therefore, we cannot process any return or refund in such cases.

No, there are no import charges to pay. We ship from our European and UK  warehouses ensuring you receive your order without any additional custom duties. If you wish to request shipping outside of Europe please email us.

Our research peptides are kept in a temperature-controlled environment at our storage facility prior to shipping

Cold shipping is particularly important for premixed peptides, which are already reconstituted and therefore more sensitive to temperature fluctuations. However, unreconstituted peptides (lyophilized) can be shipped without cold shipping, as they are shipped in their dried form, which helps preserve their structure.

Here’s why cold shipping is essential for certain peptides and why it’s not always necessary:

• Premixed Peptides: We recommend cold shipping for premixed peptides, as they are more vulnerable to temperature changes once reconstituted. Cold shipping ensures they remain at a controlled, low temperature, preserving their potency and preventing degradation.

• Unreconstituted (Lyophilized) Peptides: For lyophilized peptides, cold shipping is not necessary. These peptides are shipped in their dried form, which protects their integrity during transit. We also take great care to shield all peptides, both premixed and lyophilized, from sunlight, which can impact potency.

• Express Europe Shipping or Flat Rate Europe : For both types of peptides, we also offer Express Europe Shipping to ensure fast delivery, and also provide Flat Rate Europe  for a more economical option. Both services ensure that your peptides arrive in optimal condition while maintaining their integrity.

In short, while cold shipping is ideal for premixed peptides, unreconstituted peptides can be shipped reliably and safely via either Express Shipping or Flat Rate Shipping, with both options offering the protection needed for your peptides.

Products sold by Research Peptides Europe are non-returnable

Please send an e-mail to admin@researchpeptides-europe.com within 24 hours after placing your order. However once your order has shipped we are unable to modify/cancel your order. A member of our Research team will assist you in modifying or issuing a refund whichever is necessary.

Lyophilized refers to a process called freeze-drying. In this process, a substance, such as a peptide, is frozen and then subjected to a vacuum environment. This causes the frozen water (ice) within the substance to sublime directly from solid to vapor, effectively removing moisture from the material without causing it to melt.

The result is a dry, stable product with a longer shelf life compared to its original form. Lyophilized products are often more stable during storage and transportation, making them convenient for research applications. To research lyophilized products, they are typically reconstituted.

All of the instructions will be sent to you in a step-by-step guide. It is very easy to follow, and you will have all the necessary items sent to you to complete the process.

At Research Peptides Europe, we are committed to providing only the highest quality peptides on the market. To give you complete peace of mind, we work with trusted third-party laboratories to conduct thorough testing on every batch of our products.

Our peptides are supported by third-party Certificates of Analysis (COAs), which verify their purity, potency, and authenticity. These COAs are available upon request, so you can trust that each product meets the highest standards.

We pride ourselves on offering the best peptides in Europe—ensuring that your health and wellness are always in safe hands. When you choose us, you’re not just getting a product, you’re getting the assurance of quality, consistency, and excellence.

When dealing with peptides stored in the refrigerator, it’s essential to allow the vial to reach room temperature before reconstituting. By ensuring the vial is at room temperature before proceeding, you help maintain the quality and integrity of the peptide, ensuring optimal results in your research or application.

A Certificate of Analysis (CoA) is available for all our products.

Mannitol is a sugar alcohol widely used in peptide formulations for its stabilizing and protective properties. It enhances peptide stability by preventing degradation during processes such as lyophilization, ensuring the preservation of bioactivity. Additionally, Mannitol improves solubility, facilitates better reconstitution, and helps protect peptides from moisture, maintaining their integrity. Its excellent flow properties also contribute to more efficient handling and accurate dosing during production.

All our peptides maintain stability at room temperature for about 30 – 60 days.

However, upon reconstitution, we advise refrigerating them for optimal storage conditions.

Please see below for recommendations 

Storing peptides in the refrigerator helps maintain their stability and effectiveness by minimising degradation over time. This practice ensures that the peptides retain their optimal quality for research or application purposes.

Lyophilized peptides can be stored in the fridge for up to two years. For reconstituted peptides, the fridge can maintain their stability for about 30 days.

• Stability at Room Temperature: Lyophilized peptides can often remain stable at room temperature (20-25°C / 68-77°F) for several weeks to a few months, depending on the specific peptide.
  • Typically, around 1-3 months is considered safe for most lyophilized peptides if stored in a dry, cool place, away from direct sunlight and humidity.
• Best Practice: Although some peptides are stable at room temperature for extended periods, it’s always best to store them in a cool, dry place and avoid temperature fluctuations to preserve their potency.

Once peptides are mixed with a solvent, they should ideally be used within 30 days when stored in the refrigerator. For longer storage, freezing at -80°C is recommended, though care must be taken to avoid multiple freeze-thaw cycles.
