GLP-1 Peptides

Our GLP-1 peptides cover the three compounds researchers compare most often, sold under our own code names: EZP-1P (semaglutide), EZP-2P (tirzepatide) and EZP-3P (retatrutide). Alongside them are cagrilintide, survodutide, eloralintide and a retatrutide and cagrilintide blend. Strengths run from 5mg to 60mg, and the EZP range also comes as a boxed 10-vial kit.

What are GLP-1 peptides?

GLP-1 is a gut hormone released after meals. It drives glucose-dependent insulin release, slows stomach emptying and acts on appetite centers in the brain. The natural hormone lasts about two minutes, so research compounds are modified to last days instead.

The EZP range steps up in receptor targets. EZP-1P acts on the GLP-1 receptor only. EZP-2P adds the GIP receptor. EZP-3P adds the glucagon receptor on top of both. Survodutide pairs GLP-1 with glucagon, while cagrilintide and eloralintide work through a different hormone, amylin, and are often studied alongside the others.

How to choose GLP-1 peptides

Pick the compound by the receptor question you’re asking: single, dual or triple agonist, or amylin. Then pick the strength by how long the project runs. The price per milligram drops a lot at the bigger sizes, so EZP-2P 60mg or EZP-3P 48mg usually makes sense for longer studies.

The EZP lab reports come from Janoshik’s blind GLP-1 test, which checks a sample against semaglutide, tirzepatide and retatrutide without being told which one it is. Each report names the compound the lab found and its purity.

GLP-1 peptides: formats and prices

There are 18 products in this range: 17 single-compound vials and one blend. Single prices run from $27.00 to $168.00. All of them also come in a 5 pack (save 5%) and a 10 pack (save 10%), which you choose from the dropdown on the product page. Every product page lists the amount, the format and the SKU, so you can compare like for like before you order.

Lab testing for our GLP-1 peptides

Most of our product pages carry an independent Janoshik Analytical test report right in the photos. Each report shows the compound the lab found, the measured amount and the HPLC purity, and it has a key you can enter at janoshik.com/verify to see the original. Where a report was run on a different size of the same compound, the product page says so.

Store sealed vials in the fridge, or the freezer for long-term storage, and reconstitute with our research diluent. Every vial page lists the concentration you’ll get for each volume.

GLP-1 peptides FAQ

Are your GLP-1 peptides in stock?

Yes. Everything listed here is in stock now.

Are GLP-1 peptides for human use?

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

How do I pick a size?

Bigger vials cost less per milligram, and smaller ones make sense for short projects, since less sits open in the fridge. Each product page compares the sizes.

Can I buy in bulk?

Yes. Most products have a 5 pack that saves 5% and a 10 pack that saves 10%. Choose the quantity from the dropdown on the product page.

Do I need anything else?

Vials need a sterile diluent such as our research diluent. Tablets and the ready-made liquids don’t.
