What are research peptides?

A research peptide is a short chain of amino acids made by chemical synthesis so labs can study it. Most of them copy or tweak a signal the body already produces. Sermorelin is the first 29 amino acids of growth hormone releasing hormone, BPC-157 is a fragment of a gastric protein, and GHK-Cu is a copper-binding tripeptide found in human plasma.

Nearly every product here ships as freeze-dried powder in a sealed glass vial with the Prime label. Dry peptide is far more stable than peptide in solution, so a vial keeps for months in the freezer and only starts its shorter fridge life once you add diluent.

The research behind this range is indexed on PubMed, the free database run by the U.S. National Library of Medicine. This PubMed search is a good starting point.

How to choose research peptides

Start with the research area using the category links above, then compare sizes. Retatrutide, tirzepatide and semaglutide come in three sizes each, and the larger vials cost less per milligram.

If the field is new to your lab, begin with the compounds that have the deepest publication record: BPC-157 for repair models, the CJC-1295 and ipamorelin blend for growth hormone work, and Semax for BDNF studies.
