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 here steps up in receptor targets. GLP-1 S acts on the GLP-1 receptor only. GLP-2 TZ adds the GIP receptor. GLP-3 RT adds the glucagon receptor on top of both. Cagrilintide works through a different hormone, amylin, and is often studied alongside them.

How to choose GLP-1 peptides

Pick the compound by the receptor question you’re asking: single, dual or triple agonist. Then pick the size by how long the project runs. The per-milligram price drops a lot at the larger sizes, so a 30mg or 60mg vial usually makes sense for longer studies.

Each product page lists the generic compound name next to our code name, so you always know exactly what’s in the vial.

GLP-1 peptides: formats and prices

There are 21 products in this range: 21 single-peptide vials. Prices run from $39.90 to $589.90. 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 the lab paperwork right in the photos: certificates of analysis with HPLC purity, and for many peptides an endotoxin report and an independent Janoshik test you can verify online. Where a report was run on a different vial size of the same peptide, the product page says so.

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

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. Smaller ones make sense for short projects, since less sits open in the fridge. Each product page compares the sizes.

Do I need anything else?

Vials need bacteriostatic water to reconstitute. Capsules are ready to use.
