Frequently Asked

Yes. Research peptides can be purchased legally in the UK for laboratory research purposes only. At Imperial Peptides UK, all products are clearly labelled “For Research Use Only – Not for Human Consumption”, in line with MHRA guidelines.

Research peptides are small chains of amino acids, the building blocks of proteins. Scientists join amino acids together using a special link called a peptide bond. By changing the order of amino acids, researchers can create peptides with different properties to study in the lab.

How are peptides made in the lab?

Most peptides are made using a method called solid-phase peptide synthesis (SPPS). In simple terms:

The first amino acid is fixed onto a solid support (like a bead).
Other amino acids are added one at a time in the right order.
Special protective steps stop the wrong parts of the amino acids from reacting.
At the end, the finished peptide is released and cleaned.

This step-by-step method allows scientists to create high-purity peptides for experiments.

⚠️ Important note:

These products are supplied for laboratory research only. They are not medicines and must not be used by humans or animals.

Because we believe trustworthy research starts with trustworthy suppliers. That’s why Imperial Peptides exists — to give researchers confidence through quality, transparency, and compliance. We provide high-purity, research-use-only peptides with Certificates of Analysis, secure UK-based operations, and fast delivery, so you can focus on advancing discoveries without uncertainty.

All our peptides contain trace amounts of mannitol, a common excipient used to improve stability, solubility, and handling. It protects the peptide during freeze-drying and storage, helps it dissolve more easily when reconstituted, and ensures the vial is not visually empty despite the small peptide quantity.

Orders placed before 2pm (UK time) are dispatched the same working day. We use Royal Mail Tracked 24 or 48 services, both with full tracking.

Royal Mail 24 → usually delivered next working day
Royal Mail 48 → usually delivered within 2–3 working days

You’ll receive a tracking number as soon as your order ships.

⚠️ Please note: delivery times are estimates provided by Royal Mail and may vary during busy periods.

Our peptides are produced by experienced international manufacturing partners using solid-phase peptide synthesis (SPPS).

To ensure quality and consistency, every batch is:

Independently tested by HPLC
Supplied with a full Certificate of Analysis (CoA)
Clearly batch labelled for traceability
Subject to final inspection and quality checks in the UK before release to customers

By focusing on independent testing and verification, we ensure that researchers receive high-purity, reliable peptides for their work.

⚠️ Note: All products are supplied strictly for laboratory research use only (RUO). Not for human or veterinary use.

Quick Guide (Research Use Only):

Handling

Let vials warm to room temperature before opening (prevents moisture).
Work in a clean environment and only take what you need.

Storage

Keep lyophilised peptides at –20°C or lower, in sealed containers with desiccant.
Protect from moisture, heat, and light.
Avoid repeat freeze–thaw cycles.

Reconstitution

Less stable than freeze-dried form.
Store in refrigeration (2–8°C) for short-term use.

⚠️ Important: For laboratory research only. Not for human or veterinary use.

We do not offer blended peptides (e.g. combinations such as Ipamorelin with CJC-1295 / Mod GRF).

There are several reasons for this:

Scientific accuracy – Blends often use fixed ratios that may not be appropriate for most research applications.
Dosing clarity – When peptides are combined in one vial, the exact microgram content of each component cannot be measured accurately, which may compromise results.
Research flexibility – Purchasing peptides separately allows you to control the precise amount of each peptide you use. For example, you can combine 100 mcg of Peptide A with 100 mcg of Peptide B in the same experiment, ensuring accuracy and reproducibility.
Cost considerations – Blends are not necessarily cheaper. Buying peptides individually usually provides better value and reliability.

Our recommendation: Acquire peptides separately. This ensures your research remains accurate, reliable, and scientifically valid.

⚠️ Important: All products are sold for laboratory research use only. Not for human or veterinary use.

Yes. Each peptide batch is accompanied by a Certificate of Analysis (HPLC), so researchers can verify quality

Our peptides are typically supplied at ≥99% purity (HPLC tested). Specific purity values are provided on the CoA for each batch.

Each peptide vial is clearly labelled for traceability and quality control.

The Batch Number is shown as a combination of the SKU code + expiry date.
Example: BPC10-03/27 → where BPC10 is the SKU and 03/27 indicates the expiry date (March 2027).
