Lab Testing & QA
Analytical Methods, Quality Control & Independent Verification
SARMs and peptides are complex research compounds where even minor deviations in purity, structure, or concentration can significantly impact quality and reliability. Every batch we supply undergoes comprehensive analytical testing to ensure identity, purity, potency, and safety — independently verified before dispatch.
For wholesalers, white-label brands, and research suppliers, professional testing is both a quality requirement and a commercial safeguard. Our testing programme is built around what B2B buyers need to confidently sell, distribute, and use our products.
What Our Testing Confirms
- The correct compound is present and chemically intact
- Purity meets or exceeds ≥98% specification
- Impurities and contaminants are controlled and within limits
- Dosage is accurate and consistent across the batch
- No heavy metals, residual solvents, or cross-contamination detected
Identity & Structural Confirmation
These tests confirm that the compound is chemically correct and has not degraded, been substituted, or structurally altered during production.
- LC-MS (Liquid Chromatography–Mass Spectrometry): Confirms molecular weight, peptide chains, and SARM structure
- FT-IR (Fourier Transform Infrared Spectroscopy): Verifies chemical fingerprints and functional groups
- NMR (Nuclear Magnetic Resonance): Used where advanced structural confirmation is required
Purity & Impurity Profiling
Purity testing determines how much of the sample is the intended compound versus impurities or degradation products. Our SARMs consistently meet or exceed 98% purity.
- HPLC (High Performance Liquid Chromatography): Quantifies purity percentage and separates impurities
- UPLC (Ultra Performance Liquid Chromatography): High-resolution analysis for sensitive peptide testing
- Related Substances Analysis: Identifies by-products and degradation compounds
Dosage & Concentration Accuracy
For finished dosage forms — capsules, liquids, or pre-filled formats — accurate concentration is critical for consistency and downstream confidence.
- Assay testing for milligram-level accuracy
- Uniformity of dosage units across the batch
- Content uniformity testing for scaled production runs
Contaminant & Safety Screening
Screening ensures substances that should not be present are identified and controlled before dispatch.
- GC-MS: Residual solvent testing
- ICP-MS: Heavy metal analysis
- Cross-contamination verification between production runs
Stability, Documentation & Traceability
Testing alone is not enough — documentation and traceability are equally critical for B2B buyers managing regulated supply chains.
- Accelerated stability studies to confirm shelf life
- Full batch and lot traceability records
- Verified analytical records available per order
- COAs (Certificates of Analysis) issued per batch from accredited laboratories
Independent Third-Party Verification
All confirmatory testing is conducted through independent, EU-accredited laboratories — not in-house. This provides objective validation and removes any conflict of interest, giving brands and distributors the confidence to represent our products accurately to their own customers.
COAs are available on request for any batch. Contact your account manager or use the link below.
Testing Services for Third Parties
In addition to testing our own products, we offer analytical testing services for wholesalers, white-label brands, research suppliers, and importers who need to validate products sourced from overseas manufacturers.
If you have product that needs independent verification before you can sell or distribute it with confidence, contact us to discuss your requirements.
Frequently Asked Questions
How do you test SARMs for purity?
We use HPLC to quantify purity percentage and separate impurities, UPLC for high-resolution peptide analysis, and related substances analysis to identify by-products and degradation compounds. Our products consistently test at ≥98% purity.
How do you confirm the identity of a SARM or peptide?
Identity and structural confirmation uses LC-MS to confirm molecular weight and structure, FT-IR to verify chemical fingerprints and functional groups, and NMR where advanced structural confirmation is required.
Do you test for heavy metals and contaminants?
Yes. Every batch undergoes residual solvent testing via GC-MS, heavy metal analysis via ICP-MS, and cross-contamination verification.
Are Certificates of Analysis available?
Yes. COAs from independent, accredited laboratories are available for every batch on request via your account manager or our contact page.
Do you offer third-party testing for other suppliers' products?
Yes. We offer analytical testing services for wholesalers, white-label brands, and importers needing to validate products from overseas manufacturers. Contact us to discuss your requirements.
