GLP-1 Peptides

Our GLP-1 peptides cover the compounds researchers compare most often: semaglutide, tirzepatide (labeled Tirz), retatrutide (labeled Reta) in 10mg and 20mg, cagrilintide, and a CagriSema blend of cagrilintide and semaglutide in one vial. Semaglutide also comes in bulk packs of 10, 30 and 50 vials.

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 range steps up in receptor targets. Semaglutide acts on the GLP-1 receptor only. Tirzepatide adds the GIP receptor. Retatrutide adds the glucagon receptor on top of both. Cagrilintide works through a different hormone, amylin, and is often studied alongside semaglutide, which is the idea behind the CagriSema blend.

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. Retatrutide 20mg costs less per milligram than two 10mg vials.

Tirz and Reta are the short names on our labels. The product pages and certificates of analysis name the compounds in full, and we’ll email the certificate for your batch if you send us the batch number.

GLP-1 peptides: formats and prices

There are 6 products in this range: five freeze-dried vials and one blend vial. Prices run from $99.42 to $194.99 for a single item. Two of them also come with a free-item deal or bulk packs, which you pick from the quantity dropdown on the product page. Every product page lists the amount, the format, the tested purity and the SKU, so you can compare like for like before you order.

Purity and testing for our GLP-1 peptides

Each product page shows the tested purity for the current batch, measured by HPLC with mass spectrometry, and most of our peptides test at 99% or higher. Every vial is labeled with the compound, the amount and a batch number. The certificate of analysis is filed under that number, and we’ll email it to you on request.

Store sealed vials in the freezer, or the fridge for shorter stretches, and reconstitute with sterile bacteriostatic water. Every vial page lists the concentration you’ll get for each volume. Our vial storage case keeps ten vials upright and together.
