Research reference

Peptide Research Guide

An in-depth reference to each research peptide we supply — what it is, the mechanisms studied in the scientific literature, and its areas of laboratory research interest.

The information below is provided for scientific and educational reference only. It describes laboratory research and molecular mechanisms — it does not constitute medical, health or usage advice, and makes no claim of benefit in humans or animals. All products are supplied strictly for in-vitro research use.

Form, storage & handling

All peptides are supplied as a lyophilised (freeze-dried) powder for research. For laboratory use they are typically stored refrigerated or frozen, protected from light, and reconstituted with an appropriate sterile solution immediately before research procedures. A Certificate of Analysis for each batch is available in our COA vault.

Research peptide FAQs

The questions researchers ask us most. Everything below is scientific reference for laboratory use only — it is not medical, health or usage advice, and makes no claim of benefit in humans or animals.

Are these products for human or animal use?

No. Every product is supplied strictly for in-vitro laboratory research use only (RUO) — not for human or veterinary use, administration, consumption, or any medical, cosmetic or therapeutic purpose. All customers must be 18 or over and purchasing solely for scientific research.

What does “research use only” actually mean?

It means the compounds are intended solely for controlled laboratory research (for example in-vitro or cell-culture work) by qualified researchers. Nothing on this site is a protocol, dose or instruction for use, and no described mechanism is a claim of effect in people.

What purity are your peptides, and how are they tested?

Purity is verified to ≥99% by HPLC using an independent method. Every batch is independently third-party tested — HPLC (purity), ICP-MS (heavy metals) and LAL (endotoxin) — so what’s on the certificate is what’s in the vial.

Do you provide a Certificate of Analysis (COA)?

Yes — every batch ships with a batch-matched Certificate of Analysis, and each vial carries its lot number so the COA matches your exact batch. Certificates are available in our COA vault, before or after you order.

What form do they come in, and how should they be stored?

Peptides are supplied as a lyophilised (freeze-dried) powder. For laboratory use they are typically kept refrigerated (2–8°C) short-term or frozen for longer storage, protected from light. Once reconstituted for research, solutions are generally refrigerated and used within the timeframe set by the research protocol.

How are they reconstituted for research?

In the lab, the freeze-dried powder is reconstituted with an appropriate sterile solvent immediately before research procedures, following the researcher’s own protocol. We supply the compound and its COA only — we do not provide reconstitution ratios, doses or usage guidance.

How do I choose which peptide for my research?

Each entry in this guide sets out what the compound is, the mechanism studied in the scientific literature, and its areas of laboratory research interest — use these to compare and shortlist. We can’t advise on selection or use; this guide is scientific reference only.

How quickly do you ship, and is it discreet?

Same-day UK dispatch on orders placed before 2pm, in plain, tamper-evident, cold-chain packaging with full UK tracking. UK shipping is free over £99.

How can I pay?

Card, Apple Pay and Google Pay, bank transfer, and cryptocurrency (10% off when you pay with crypto). All secured at checkout.

What is your returns policy?

Because these are research reagents, we can accept returns of unopened items in their original tamper-evident packaging — just contact us. For safety and research integrity, opened vials cannot be returned. If anything arrives damaged, contact us straight away and we’ll put it right.

Do you ship internationally?

To selected countries. It is the buyer’s responsibility to confirm that importing research reagents is legal in their own jurisdiction before ordering.
