No UK trading entity found
We searched UK Companies House thoroughly (exact name, exact phrase, and plausible variants) and found no matching registration, despite this site presenting as UK-based. This caps the CoA tier below green regardless of score. It is not proof of wrongdoing, only that we could not confirm who operates this business: see methodology.
- ⚠ Publishes benefit claims next to products despite research-only framing
- ⚠ No UK trading entity could be found despite a thorough search, though the site presents as UK-based

Responsible Practice assessment
Clear and responsible- · 'Investigating', 'Studying', 'Research into' throughout -- properly research-framed.
- · Benefit-claim language observed on site: "Synergistic GH Secretion: Investigating the potential for significantly higher GH release compared to single-peptide administration. / Enhanced Tissue Repair: Studying the role of combined hormonal signaling in accelerating the recovery of muscle and connective tissue. / Metabolic Optimization: Research into the synergistic impact on fat oxidation and energy homeostasis. (from an Ipamorelin blend product page; homepage also references 'lean-tissue and metabolic recovery research' for Ipamorelin and 'Collagen and extracellular matrix research' for a 'Glow' product)"
We assess what a brand publishes and makes available to customers, not its intentions. Full framework and what each status means: how we assess brands. Think this is wrong? Email [email protected] with evidence.
Not yet Independently Verified
The CoA tier and Responsible Practice status above are free and mechanical. Nobody, including R&D Peptides, has paid for the deeper lab-accreditation, batch-traceability, and corporate-history checks yet. Request that it be run →
