FAQ · Research peptides
What does "research use only" actually mean?
"Research use only, not for human or animal consumption" is the regulatory framing under which research peptides without UK MHRA marketing authorisation are sold in the UK. The wording positions the product outside the medicines tier of the Human Medicines Regulations 2012. It is not a positive regulatory category that authorises any specific use; it is the absence of medicines licensing. The framing fails the moment a retailer adds therapeutic claims, at which point MHRA enforcement scope opens.
What the framing does
- · Marks the product as not intended for use as a medicine.
- · Removes therapeutic claims from product pages (no "treats", "cures", "improves" wording).
- · Positions the supplier as a chemical retailer, not a pharmacy or prescriber.
- · Keeps the product outside the MHRA medicines licensing regime under the Human Medicines Regulations 2012.
What it does not authorise
- · It does not authorise human use. The framing is the opposite of that.
- · It does not exempt the retailer from honest descriptive claims under consumer protection law.
- · It does not place the product in any positive regulatory category. The product sits outside the medicines tier rather than inside any other tier.
- · It does not exempt the product from VAT, customs, or general commerce regulations.
When the framing fails
A retailer adding any therapeutic claim (for example, stating that a peptide treats, heals or improves a condition in humans) immediately puts the product in scope of the Human Medicines Regulations 2012, which means selling an unlicensed medicinal product. MHRA enforcement action against UK retailers in 2024 to 2025 focused on exactly this pattern: compliant research-use-only product labels but therapeutic claims elsewhere on the site (blog posts, customer testimonials, influencer marketing).
Why PeptideClear uses this framing
We treat research peptide content as encyclopedic: what the molecule is, what the preclinical literature shows, what UK regulatory status is. We do not publish dosing protocols, missed-dose advice, or human-use instructions. This is editorially constrained by the same regulatory frame that constrains retailers; making therapeutic claims would put us in scope of the same regulations.
