Quality & Testing

Every batch is independently tested by a certified external laboratory to verify purity, identity, and composition. Each analysis uses advanced methods such as HPLC and mass spectrometry, guaranteeing the highest research quality.

  • Verified purity: every batch is tested for peptide integrity and composition.
  • Third-party certified: analysis is performed by accredited laboratories using validated testing procedures.
  • Transparent results: the corresponding Certificate of Analysis (COA) and analytical data are on our Lab Results page.

All My Peptides Lab products undergo strict processing, temperature control, and documentation to guarantee consistency and traceability from production to shipment.

Important questions answered by professionals

*Answered by independent medical researchers and licensed physicians

What is RT3 as a research peptide?

RT3 is a synthetic peptide of 39 amino acids with non-coded residues and a C20 fatty diacid conjugation for stability and albumin binding. It is studied in laboratory and in-vitro research for its activity on multiple endogenous receptor pathways. RT3 is sold by MyPeptidesLab strictly for in-vitro research and has not been approved by the EMA, FDA, or any national medicines authority.

What is RT3 studied for in research?

In preclinical and in-vitro studies, RT3 is being researched in relation to multiple metabolic receptor pathways and as a tool in metabolism research. Research also describes effects on processes related to body composition in study models. Research findings are preliminary and require further validation.

What is included in the Certificate of Analysis (CoA) for RT3?

The batch-specific CoA for RT3 shows an HPLC purity of 99% or higher, identity confirmation via mass spectrometry, the batch number, and the net peptide content in milligrams per vial. The CoA is published on the product page so you can review it before ordering.

How do you verify the purity of peptides?

Every batch is HPLC-tested by an independent external laboratory for a purity of 99% or higher, with identity confirmation via mass spectrometry. The batch-specific Certificate of Analysis is published on every product page.

How quickly is my order delivered and which carriers do you use?

Orders placed before 15:00 CET are shipped the same business day from the Netherlands via PostNL, including on Saturdays. Delivery within the EU typically takes 2–5 business days, fully tracked. Every package is shipped in neutral, unbranded packaging with no visible references to peptides.
