Royal Peptides review: is it legit?

Live Transparency score 52/100 Checked Oct 15, 2026. Visit royal-peptides.com

Regulatory or legal action: FDA warning letter to Royal Peptides LLC (Aug 24, 2026). Details and sources.

We leave vendors named in an FDA warning letter, lawsuit, seizure or other regulator action in the past three years out of our rankings, shortlists and alternatives. This profile and its prices stay published.

Our findings in brief

In short: Royal Peptides scores 52/100, higher than 55% of the 192 active vendors we track. We don't rank it, because it was named in an FDA warning letter (Aug 2026).

We haven't lab-tested anything from Royal Peptides, so this covers public evidence only, not product quality. As of Oct 15, 2026:

History and alerts

Aug 24, 2026: FDA warning letter to Royal Peptides LLC. FDA reviewed royal-peptides.com in July 2026 and classed its tirzepatide, semaglutide, retatrutide, SS-31, PT-141, tesamorelin and 'BIMORELIN' products as unapproved new drugs. It said bacteriostatic water sold alongside a 'peptide guide' and 'peptide calculator' showed the products were intended for human use. [1]
