About us
An analytical laboratory built for peptides.
MyPeptideTesting is an independent testing laboratory for research peptides. We answer one question for every lot submitted: does the material match what its label claims — in identity, purity, content and safety-relevant impurities.
Methodology
Replicate measurement is the basis of a reliable result.
Variability arises from both the product and the analytical process. Replicate testing allows the two to be distinguished and quantified.
Intra-batch variability
Fill weight, residual moisture and degradation differ between vials of a single lot. A single vial is not representative of the batch.
Run-to-run variability
Column condition, detector response and calibration drift between runs. Repeated analysis of one vial yields a distribution of results, not a single value.
Replication and reporting
Up to twenty determinations per lot are averaged. Results are reported as a mean with standard deviation, and outlying vials are identified.
How we operate
Independent by design.
- We test; we do not manufacture, distribute or endorse any product. Results carry no commercial interest in the outcome.
- Every lot receives one batch-specific certificate of analysis, never a template, verifiable on this site by its report ID.
- Methods are declared on each certificate: RP-HPLC with UV detection, LC-MS identity confirmation, and compendial methods (USP) for endotoxin, sterility and particulates.
- Quantitative results are reported as a mean with standard deviation across replicates, with the replicate count stated.
Scope
What we test.
- Research peptides as raw API, lyophilized vials, nasal sprays, tablets and capsules.
- Peptide blends and bacteriostatic water.
- Panels from 8 to 20 assays per lot, priced per sample on the Submit Samples page.
We operate a quality management system based on ISO/IEC 17025. Peptide testing is not within an accreditation scope and is provided for research use only. Analytical testing is not regulatory approval, and results apply only to the samples submitted.
