What are research peptides?

Research peptides are short chains of amino acids made by chemical synthesis for laboratory work. Most are copies or modified versions of peptides the body makes itself, such as fragments of growth hormone releasing hormone, gut hormones like GLP-1, or repair signals like thymosin beta-4.

They’re sold as freeze-dried (lyophilized) powder because a dry peptide is far more stable than one in solution. You add sterile bacteriostatic water when you’re ready to use it, and the clock on its shelf life starts then.

How to choose research peptides

Start with the research area, using the groups below. If you already know the compound, compare strengths on its product page: bigger vials usually cost less per milligram, and smaller ones mean less sits open in the fridge.

New to research peptides? The best-documented starting points are BPC-157 for repair models, ipamorelin or CJC-1295 No DAC for growth hormone work and SEMA-1 (semaglutide) for GLP-1 research. Each has a large published literature behind it.

Research peptides: formats and prices

There are 63 products in this range: 56 freeze-dried vials, five blend vials and two raw powders. Prices run from $34.00 to $199.00. Every product page lists the amount, the format and the SKU, so you can compare like for like before you order.

Quality and handling for our research peptides

Every product in this range carries a label with the product name and amount. If your lab needs batch paperwork on file, contact Peptira support before you order and ask what’s available for the current batch. Labs that check incoming material themselves usually confirm identity by mass spectrometry and measure purity by HPLC.

Store sealed vials in the freezer and reconstitute with bacteriostatic water. Every vial page lists the concentration you’ll get for each volume, and our 10 vial kit case keeps vials upright in the fridge.

Ordering and shipping

Every order ships free, with no minimum, to the US, Canada, Europe, Australia and the rest of the world. Orders are packed so vials stay upright and protected in transit, and freeze-dried powder is stable at room temperature for the journey.
