What are research peptides?

A research peptide is a short chain of amino acids made by chemical synthesis so labs can study it. Many copy a signal the body already makes. Tesamorelin is a stabilized version of growth hormone releasing hormone, Selank is built on the immune peptide tuftsin, and GHK-Cu is a copper-binding peptide found in human plasma.

Our vials hold freeze-dried powder. Dry peptide lasts far longer than peptide in solution, so a sealed vial keeps for months in the freezer. The clock only starts once you add bacteriostatic water.

The research behind this range is indexed on PubMed, the free database of the U.S. National Library of Medicine. Start with this PubMed search.

How to choose research peptides

Start with the research area. The category links on this page split the range into metabolic, growth hormone, repair, brain, longevity, skin and hormone work. Then compare sizes on the product page, where the bigger vials usually cost less per milligram.

New to a field? Begin where the published work is deepest: BPC-157 for repair models, GLP-2 TZ for incretin research and the CJC-1295 and Ipamorelin blend for growth hormone studies.

Research peptides prices

This range has 28 products, with prices from $40.00 to $125.00. 5 of them come in more than one size or version, chosen from the menu on the product page. Shipping is free on every order, to any country we ship to.

Research peptides lab testing

20 of the 28 products here have a certificate of analysis in their product photos. Most come from Freedom Diagnostics, a US lab that measures purity by HPLC and confirms identity by mass spectrometry. Each product page lists the purity results and the search code you can use to look the report up yourself.

Storage and handling

Keep sealed freeze-dried vials in the freezer at -20°C, or in the fridge if they’ll be used within a few weeks. Once a vial is mixed, it stays at 2 to 8°C and is best used within about four weeks.

Write the arrival date and, later, the mixing date on every vial or bottle. Those two dates answer most questions later.
