Research Peptides

Every research peptide Polaris Peptides sells is on this page: semaglutide, tirzepatide and retatrutide in several strengths, newer metabolic compounds like survodutide and mazdutide, growth hormone peptides, BPC-157 and TB-500, thymus peptides, nootropic peptides, melanocortins and the GLOW and KLOW blends. Each batch is checked by HPLC-MS, most test above 99% purity, and every vial is vacuum-sealed.

Shop by research area: GLP-1 peptides, weight loss peptides, growth hormone peptides, healing and recovery peptides, immune peptides, anti-aging peptides, nootropic peptides and skin and tanning peptides. Or see peptide blends, topical peptides and peptides on sale.

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 gut hormones like GLP-1, fragments of growth hormone releasing hormone or the copper-binding GHK found in plasma.

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 above. 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 semaglutide for GLP-1 research. Each has a large published literature behind it, so your results are easy to compare with other labs.

Research peptides: formats and prices

There are 60 products in this range: 53 freeze-dried vials and seven blend vials. Prices run from $30.00 to $400.00. 18 of them are on sale right now. Every product page lists the amount, the format and the SKU, so you can compare like for like before you order.

Purity and testing for our research peptides

Every batch in this range is checked by HPLC-MS, which measures purity and confirms the molecular weight in one test. Most products test above 99% purity, and each product page states its figure. Vials are vacuum-sealed after freeze-drying to keep air and moisture out.

Store sealed vials in the freezer at -20°C and reconstitute with sterile bacteriostatic water when you’re ready. Every vial page lists the concentration you’ll get for each volume of water. Mixed vials go in the fridge at 2 to 8°C and should be used within 28 days.

Bulk pricing on research peptides

Most products here come in packs as well as single vials. Pick 2, 5, 10, 15 or 20 in the Quantity menu on the product page, and the price per unit drops by 10% to 30%. Packs ship as individual sealed vials, so you only open what you need.

Research peptides FAQ

Are your research peptides in stock?

Yes. Everything listed here is in stock and ready to ship.

Are research peptides for human use?

No. Everything we sell is for laboratory research only and isn’t approved for human or veterinary use.

How pure are they?

Most test above 99% by HPLC-MS. Each product page shows the purity figure for that product.

Is there a bulk discount?

Yes. Choose a pack of 2 to 20 in the Quantity menu on any product page and save between 10% and 30%.

Do I need anything else?

Sterile bacteriostatic water to reconstitute the vials, and a fridge and freezer for storage.
