"Research use only" framing

Research peptides without UK marketing authorisation (BPC-157, TB-500, Ipamorelin, Sermorelin, Tesamorelin, MOTS-c and many others) are sold by UK retailers under a "research use only, not for human or animal consumption" framing. This wording is what positions the product outside the Human Medicines Regulations 2012 medicines tier.

What the framing does

• · Marks the product as not intended for use as a medicine.
• · Removes therapeutic claims from the product page (no "treats", "cures", "improves").
• · Positions the supplier as a chemical retailer, not a pharmacy or prescriber.
• · Keeps the product outside the MHRA medicines licensing regime.

What it does not authorise

• · It does not authorise human use of the peptide. The framing is the opposite of that.
• · It does not exempt the retailer from making honest descriptive claims; misleading purity claims would still be in scope of 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.

When the framing fails

A retailer adding any therapeutic claim ("BPC-157 heals tendons", "TB-500 reduces inflammation 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 has focused on exactly this pattern: research-use-only labelling on the product page but therapeutic claims in the marketing copy elsewhere on the site.

Why this matters to readers

The research-use-only framing is meaningful: it sets the regulatory context that the peptide is not approved for human use in the UK. PeptideClear treats all research peptide content as encyclopedia information about the molecule and the literature, not as guidance for human use. We do not publish dosing protocols, missed-dose advice, or human-use instructions for research peptides.
