Question 1

What is a research peptide?

Accepted Answer

A short chain of amino acids studied for its activity at a specific receptor or pathway. The catalogue groups compounds by that pathway, not by a claimed outcome, because the pathway is the fact and the outcome is not one we assert.

Question 2

Are the compounds in this catalogue tested on humans or animals?

Accepted Answer

No. Every compound is catalogued for in-vitro laboratory research only. Nothing on this site describes or implies human or animal administration.

Question 3

How are the six research categories organised?

Accepted Answer

By mechanism: the receptor family or signalling pathway a compound is studied against, for example growth hormone secretagogues or matrix and epithelial signalling. Categories describe a pathway, not a benefit.

Question 4

Is NAD+ a peptide?

Accepted Answer

No. NAD+ is a dinucleotide coenzyme, not a peptide, and is catalogued under Metabolic and Mitochondrial rather than described as a research peptide.

Question 5

Where can I read the research context for a specific compound?

Accepted Answer

Each product page carries a Research Context tab describing the pathway and receptor activity studied for that compound, with the Analysis and Documentation and Compliance Notice tabs alongside it.

Question 6

Are research peptides legal in the United Kingdom?

Accepted Answer

Compounds catalogued here are not licensed medicines and are not regulated as such by the Medicines and Healthcare products Regulatory Agency (MHRA). They are catalogued for in-vitro laboratory research only, and it remains the research user’s responsibility to comply with the laws that apply in their own jurisdiction.

Question 7

Do I need to work at a registered laboratory to access the catalogue?

Accepted Answer

Access requires only a self-declared confirmation that you are 18 or over and accessing the catalogue in a research capacity. We do not verify institutional affiliation.

Question 8

Can any compound in this catalogue be used on humans or animals?

Accepted Answer

No. Every compound is for in-vitro laboratory research only. No compound is supplied as a medicine, a supplement, or for veterinary use, and no guidance on administration is provided or will be provided on request.

Question 9

What happens if a compound cannot be listed to my location?

Accepted Answer

A small number of compounds carry destination restrictions, stated on that compound’s page. An order placed for a restricted destination is blocked at checkout and, if one is placed in error, cancelled and refunded in full.

Question 10

Who is responsible for compliance once an order is dispatched?

Accepted Answer

The research user. That includes compliance with the Control of Substances Hazardous to Health Regulations 2002, or the equivalent regime in their jurisdiction, covering receipt, handling, storage, use and disposal.

Question 11

What does "in-vitro laboratory research only" mean in practice?

Accepted Answer

The compound stays in a laboratory setting. It is not for human or veterinary use, not for the diagnosis, treatment, prevention or cure of any condition, and not for ingestion, injection, inhalation, topical application or any other form of administration. No guidance on preparation, quantity or administration is provided, and none will be provided on request.

Question 12

Are these compounds medicines?

Accepted Answer

No. They are not medicinal products within the meaning of the Human Medicines Regulations 2012, they are not licensed by the Medicines and Healthcare products Regulatory Agency, and they carry no marketing authorisation. Protocol Peptides is not a pharmacy, is not a licensed manufacturer or wholesale dealer of medicinal products, and does not compound, prescribe or dispense.

Question 13

Are they supplements, foods or cosmetics?

Accepted Answer

No. They are not food, food supplements, novel foods or cosmetics, and they are not marketed as such. The full position is set out in the Research Use and Compliance Statement.

Question 14

What has to be confirmed before an order can be placed?

Accepted Answer

That you are 18 or over, that the compounds are ordered for laboratory research only, and that they will not be used for human or veterinary consumption or for any medical, diagnostic or therapeutic purpose. The confirmation is a separate box at checkout, unticked until you tick it, and the time, a truncated IP address and a record of the exact wording shown are kept with the order.

Question 15

Do you provide Certificates of Analysis (COAs)?

Accepted Answer

Yes. Every batch is independently analysed and its Certificate of Analysis is published before that batch is listed. Your batch number links directly to the raw test data at Verification.

Question 16

What analytical methods are used?

Accepted Answer

Two: high-performance liquid chromatography (HPLC) for purity, and mass spectrometry for identity confirmation. No other assay is performed or implied for any compound in this catalogue.

Question 17

Does a batch’s result apply to every vial of that compound?

Accepted Answer

No. A Certificate of Analysis reports on the specific batch identified on it. Results for one batch do not warrant any other batch, past or future.

Question 18

How do I find the Certificate of Analysis for the vial I am holding?

Accepted Answer

Enter the batch number printed on the vial label at Verification, or go directly to protocolpeptides.co.uk/verification/ followed by the batch number. The record resolves by exact match.

Question 19

My batch number does not resolve to a record. What do I do?

Accepted Answer

Check for a transposed character and try again. If it still does not resolve, email us with the batch number and your order number; we will publish the record or correct it, and tell you which.

Question 20

When is a Certificate of Analysis published?

Accepted Answer

When the batch is released. The report is published against that batch number before the compound it belongs to becomes orderable. It is not held back and it is not issued only on request.

Question 21

What is on a Certificate of Analysis?

Accepted Answer

The batch number, the compound and its presentation, the date of analysis, the purity figure measured for that batch by HPLC, and the identity result returned by mass spectrometry. Those two methods are the whole analytical panel and no further assay is performed or implied.

Question 22

How should the purity figure on a certificate be read?

Accepted Answer

As a measurement of the batch named on that document, not as a threshold applied to the catalogue. We publish the figure the analysis returned for that batch. A result for one batch does not warrant any other batch, before it or after it.

Question 23

Is an account needed to read a certificate?

Accepted Answer

No. Every published record is readable at Verification without an account, and the batch number printed on the vial resolves straight to its report.

Question 24

What presentation do compounds ship in?

Accepted Answer

A sealed, pre-mixed liquid in a 3ml vial, ready for laboratory use with nothing to prepare beforehand.

Question 25

What does "Awaiting batch" mean?

Accepted Answer

The compound has not yet had a batch analysed and listed, so it cannot currently be ordered. It remains catalogued, with its full research context and compliance record, and becomes orderable once a batch is released.

Question 26

Can I order a compound before its Certificate of Analysis is published?

Accepted Answer

No. A compound is not orderable until a batch has been analysed and its Certificate of Analysis published, on the client and on the server.

Question 27

Where is the catalogue dispatched from?

Accepted Answer

The United Kingdom. At launch, dispatch is to United Kingdom addresses only.

Question 28

Is VAT included in the price shown?

Accepted Answer

Where VAT applies, it is shown as its own line at checkout before an order is placed. No charge is added after that point.

Question 29

Can a larger quantity than the catalogue lists be requested?

Accepted Answer

By enquiry. No quantity tier is published on the site, so send the compound and the quantity you need through the contact form with "Catalogue enquiry" as the subject, and we reply within two working days.

Question 30

How is payment taken?

Accepted Answer

Prices are shown in pounds sterling, and the price you pay is the price displayed at the point you place the order. Payment is taken by our payment provider, and full card details are not held by us. Delivery charges, and VAT where it applies, are shown in full at checkout before the order is placed.

Question 31

Can an order be cancelled after it has been placed?

Accepted Answer

Yes, under the 14 day right to cancel, which runs from the day after the goods arrive and holds for as long as the vial seal is intact. Email us with your order number, or use the model cancellation form. The full position, including the two limited exceptions, is in Cancellations, Returns and Refunds.

Question 32

Which destinations can an order be delivered to?

Accepted Answer

United Kingdom addresses at launch, dispatched from the United Kingdom. Every destination we deliver to sits on a published allowlist, and an order placed for a destination a compound cannot be listed to is blocked at checkout.

Question 33

Is every order tracked?

Accepted Answer

Yes. Every order is sent on a tracked service, and the tracking reference is emailed to you at dispatch.

Question 34

How quickly is an order dispatched?

Accepted Answer

Orders are checked and prepared for dispatch within the working-day window published on Dispatch and Delivery. An order placed at a weekend or on a bank holiday is processed on the next working day. Times after dispatch are carrier estimates.

Question 35

What does the packaging look like?

Accepted Answer

The outer packaging is plain and carries no compound name. The inner packaging carries the compound name, the presentation, the batch number and the research-use-only marking.

Question 36

Is anything dispatched under temperature control?

Accepted Answer

Where the compound requires it, and only where that is stated on the compound’s page. Storage and Handling lists temperature-controlled dispatch per compound alongside that compound’s storage condition.

Question 37

A parcel arrived damaged, or has not arrived at all. What now?

Accepted Answer

Email us within 48 hours of delivery with your order number and photographs of the outer packaging, the inner packaging and the vial, or within 7 days of the expected delivery date where nothing has arrived. If a seal is broken or the packaging has been opened, do not use the contents.

Question 38

How should a vial be stored before use?

Accepted Answer

As published on that compound’s page and on Storage and Handling. Where a condition has not yet been confirmed for a compound, it is stated on the dispatch note that arrives with the vial rather than guessed on the page.

Question 39

What should I check when a vial arrives?

Accepted Answer

The seal, the vial and the outer packaging, before anything else. If anything looks broken or tampered with, do not use the contents, and email us within 48 hours with your order number and photographs.

Question 40

Does a vial need any preparation before laboratory use?

Accepted Answer

No. Every compound ships as a pre-mixed liquid, ready for laboratory use as supplied.

Question 41

Can a vial be returned once the seal is broken?

Accepted Answer

No. The 14-day right to cancel applies while the seal is intact and is lost for that vial once it is broken. The full position is in Cancellations, Returns and Refunds.

Question 42

How should an opened or unwanted vial be disposed of?

Accepted Answer

Under the waste rules that apply in your jurisdiction and your own organisation’s procedure. Do not place a vial with residual contents into general waste, and do not pass an opened vial to anyone else.
