Important questions answered by professionals
*Answered by independent medical researchers and licensed physicians
What is PE-22-28 as a research peptide?
PE-22-28 is a synthetic heptapeptide fragment derived from the spadin sequence. It is the smallest identified fragment that shows activity on the TREK-1 channel comparable to spadin. PE-22-28 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 PE-22-28 studied for in research?
In preclinical and in-vitro studies, PE-22-28 is being researched in relation to the TREK-1 channel, with a high affinity and specificity compared to spadin. Research focuses on study models involving neuroprotection, mood regulation, and the formation of new nerve cells. Research findings are preliminary and require further validation.
What is included in the Certificate of Analysis (CoA) for PE-22-28?
The batch-specific CoA for PE-22-28 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.
Does MyPeptidesLab offer bulk or wholesale orders for peptides?
