Research peptides are laboratory-grade peptide compounds sold in the UK under "research use only, not for human or animal consumption" framing. Sold without medicinal claims, they sit outside the MHRA medicines tier. The UK retailer pool includes my-peptides, Pure Peptides UK, Direct Sarms, Aquila, Pinnacle and Nooku. PeptideClear is editorial and informational only. Preclinical literature is summarised in encyclopedia format. We do not sell, we do not recommend dosing, and we do not endorse human use.

UK regulatory framing (briefly)
- · The Medicines Act 1968 + Human Medicines Regulations 2012 govern any product marketed as a medicine in the UK.
- · Research peptides marketed as "research use only" with no health claims sit outside that tier.
- · Once a retailer or commentator makes a health claim ("heals tendons", "improves recovery", "use at X mg"), the product is treated as an unlicensed medicinal product. MHRA enforcement follows.
- · £45m of trafficked weight-loss medicines and "peptide products" were seized by MHRA in early 2026 (Northampton Oct 2025, Sleaford 2026). Sites making medicinal claims are the enforcement priority.
Our editorial framing on every research peptide page is encyclopedia. History, mechanism, animal literature, regulatory status. No dosing, no human-use protocols, no cycle stacks. Where we link out to retailers, the retailer's "research use only" framing applies to the transaction.
