GLP-1 Peptides

Our GLP-1 peptides cover the incretin and amylin compounds researchers compare most: SEMA-1 (semaglutide) in 10mg and 20mg, TIRZ-2 (tirzepatide) from 10mg to 60mg, RETA-3 (retatrutide) in 10mg, 20mg and 30mg, CAG-4 (cagrilintide) 10mg and survodutide 10mg. Every vial is in stock and ships free worldwide.

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. SEMA-1 acts on the GLP-1 receptor only. TIRZ-2 adds the GIP receptor, and RETA-3 adds the glucagon receptor on top of both. Survodutide pairs GLP-1 with glucagon, and CAG-4 works through a different hormone, amylin.

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. TIRZ-2 60mg costs about $3.32 per milligram against $8.90 for the 10mg vial.

SEMA-1, TIRZ-2, RETA-3 and CAG-4 are our code names for semaglutide, tirzepatide, retatrutide and cagrilintide. Each product page names the compound in full.

Code names explained

SEMA-1, TIRZ-2 and RETA-3 are numbered by how many receptors each compound targets: one for semaglutide, two for tirzepatide and three for retatrutide. CAG-4 is cagrilintide, the amylin analog.

Survodutide is sold under its own name. It targets GLP-1 and glucagon, the same pair as RETA-3 without the GIP receptor.

GLP-1 peptides: formats and prices

There are 11 products in this range: 11 freeze-dried vials. Prices run from $69.00 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 GLP-1 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.
