Quality & Testing

Quality & Testing

Every product Goated Peptides supplies is a research compound intended for in-vitro laboratory work only. Because reproducible work depends on material you can characterise, each lot is analysed for identity and purity, and the results are documented against the lot number so you can verify exactly what you are working with.

The short version: RP-HPLC purity analysis with LC-MS identity confirmation on every lot, results recorded on a lot-specific Certificate of Analysis, and that certificate available to review by batch number before or after purchase. Not for human or animal consumption.

Analysis

Two complementary methods on every lot

Purity and identity are different questions and they need different instruments. Each production lot is analysed by both before it is released, and the results are recorded against the lot number.

Method 01

Reversed-Phase High-Performance Liquid Chromatography

RP-HPLC · Purity quantification

RP-HPLC separates a sample into its individual components so the proportion of the target peptide can be measured against any impurities. The resulting figure is the purity percentage recorded on that lot’s Certificate of Analysis.

Method 02

Liquid Chromatography Mass Spectrometry

LC-MS · Identity confirmation

Mass spectrometry confirms that the compound in the vial is the peptide named on the label by matching its measured mass to the expected molecular weight for that sequence.

Together these answer both questions: what the compound is and how pure it is. Both figures are recorded per lot rather than quoted as a catalogue-wide average, so the number you read is the number measured for the vial you receive.

Rigour

Reference standards and analytical rigour

Test results only mean something if the method behind them is consistent and the sample can be traced. Our analytical workflow is built around documented methods and lot-level record keeping.

Reference comparison

Identity confirmation is assessed against the expected molecular weight for the published sequence, so the result is checked against a known value rather than an internal assumption.

Known value comparison

Documented methods

The same analytical methods are applied to every lot and recorded on the certificate, so results stay comparable from one batch to the next.

Consistent and repeatable

Lot-to-lot traceability

Every vial carries a lot number that maps to a single analytical record, so material on your bench can always be traced back to the analysis that released it.

Documented & auditable

Handling

Presentation, lyophilisation and handling

Peptides are supplied as a lyophilised (freeze-dried) white powder. Lyophilisation removes water under vacuum, which keeps the material stable through storage and transport far better than a solution would.

Storage on arrival

  • Store lyophilised material under the conditions specified for that material, as printed on the vial label and stated in its documentation, protected from light.
  • Allow vials to reach room temperature before opening to avoid condensation on the contents.
  • Keep the original label intact so the lot number stays traceable to its analytical record.

Storage conditions and handling notes are stated on the label and on individual product pages. Responsibility for storage, handling and disposal passes to you on delivery.

Compliance

Research Use Only

All Goated Peptides products are sold strictly for laboratory research. They are not drugs, supplements, cosmetics, or foods, and they are not intended for human or animal consumption. By ordering, buyers confirm they are qualified researchers purchasing for legitimate scientific use. Full terms are set out in our Research Use Policy and Compliance Overview.
