Science.
Integrity.
Results.
We are a UK-based peptide research company built by athletes and scientists who believed the supplement industry could do better. So we built it.
Built on Evidence,
Not Hype
Ursine Amino Research was founded on a single, non-negotiable principle: every product we create must be backed by science. Not influencer endorsements, not proprietary blends, not underdosed formulas hiding behind clever branding.
We work directly with certified peptide synthesis laboratories in the UK and Europe, maintaining full traceability from raw amino acid sequencing through to the finished product in your hands.
Every batch is independently third-party tested before release. Every formulation is built from peer-reviewed clinical literature. No shortcuts. No compromises.

Our Core Values
Every Certificate of Analysis is published publicly. You can verify exactly what is in your product — down to the exact amino acid ratios and contaminant testing results.
We only formulate at doses that appear in the clinical literature. No token inclusions. If a compound isn't dosed to have a meaningful effect, it isn't in our products.
Our formulations are reviewed and updated as the science evolves. We do not lock products in and walk away — we iterate as new peptide research emerges.
Every product is tested internally by competitive athletes and reviewed by sports nutritionists before it reaches the public. Performance matters as much as the data.
All products are manufactured and tested within UK-regulated facilities, adhering to GMP standards. We do not outsource quality control.
We believe an informed customer is our best customer. Our research journal, ingredient guides, and COA library are free and open to everyone.
How We Got Here
Frustrated by the gap between peptide science and what was available on the market, our founder begins two years of independent research into bioactive amino acid sequencing.
Company incorporated in the UK. First laboratory partnerships established. Initial product formulations developed and third-party tested.
BearFuel EAA Complex and Glutamine Pro release to the public. Immediate adoption by competitive athletes and sports nutrition coaches.
Our most complex formulation to date launches — a full-spectrum peptide matrix combining EAAs, collagen peptides and HMB. Becomes our best-selling product within 3 months.
Expanding our research journal, growing the product line, and deepening laboratory partnerships. The mission remains unchanged: rigorous science, uncompromising purity.
