I've been sourcing peptides for longevity research for six years. UNIK LAB is the first supplier where purity matched the documented figures every single time. No exceptions.
European stock and 48h dispatch make a genuine difference for time-sensitive protocols. The packaging is discreetly packaged and the team responds to research queries the same day.
Every decision at UNIK LAB is made with scientific rigour and researcher trust in mind.
Everything you need to know about research-grade peptides, quality standards, and ordering.
A research-grade peptide is a synthetic amino-acid chain manufactured under strict analytical controls for use in in-vitro laboratory studies. Unlike pharmaceutical-grade compounds, research-grade peptides are intended solely for scientific investigation — not for human or veterinary administration. At UNIK LAB, every batch is verified by independent HPLC and mass spectrometry before dispatch.
Purity directly determines experimental reliability. A peptide at 85% purity contains up to 15% unknown impurities that can confound assay results, trigger off-target responses in cell models, or degrade faster. HPLC (High-Performance Liquid Chromatography) at ≥98% is the accepted threshold in peer-reviewed research to ensure that observed biological effects are attributable to the compound itself, not to contaminants or truncated sequences.
A Certificate of Analysis (COA) is an official document issued by an independent third-party laboratory certifying the identity, purity, and composition of a specific batch of compound. It includes: the HPLC chromatogram (purity % by area), mass spectrometry data confirming molecular weight, batch number, and synthesis date. A valid COA comes from an accredited, external lab — not the supplier's own facility. UNIK LAB publishes all COAs on the Certificates page.
Approved medications have completed multi-phase clinical trials demonstrating safety and efficacy in humans, and carry regulatory authorisation (FDA, EMA, etc.) for specific indications. Research peptides have not undergone this process — they are experimental compounds studied to understand biological mechanisms. They are not prescribed, dispensed through pharmacies, or intended for therapeutic use. Purchasing research peptides for self-administration is outside their legally defined purpose.
Lyophilized peptides stored at -20°C in a dry, dark environment are typically stable for 12–24 months from the synthesis date. Once reconstituted in bacteriostatic water, stability decreases significantly: most peptides should be used within 4–8 weeks when stored at 4°C, and repeated freeze-thaw cycles should be avoided. Specific stability data varies by compound — always refer to the published literature and the COA for each batch.
UNIK LAB ships to the European Union, the United Kingdom, and a broad range of international destinations. We maintain European stock for faster EU/UK delivery. It is the buyer's sole responsibility to verify that importing and possessing research compounds is lawful in their jurisdiction before placing an order. We do not ship to sanctioned countries or regions where these compounds are explicitly prohibited by law.
