GLP search guide
GLP-1, GLP-2, and “GLP-3”: what each term means.
These terms are not interchangeable. Compare the exact compound name and receptor targets, then review the product-specific research note and details.
GLP-1
An established incretin hormone.
GLP-1 receptor research includes semaglutide and also appears within the multi-receptor profiles of tirzepatide and retatrutide.
Shop GLP-1 products
GLP-2
A separate peptide.
GLP-2 means glucagon-like peptide-2, a distinct peptide associated mainly with intestinal biology. It is not another name for tirzepatide.
Read the difference
GLP-3
Informal shorthand, not a formal label.
“GLP-3” is sometimes used for triple-agonist research such as retatrutide. Compare the exact compound name and receptor targets.

Frequently asked questions
Common questions before you buy.
What makes Research Chem different from a normal peptide site?
You can compare strengths, pricing, savings, and stock quickly. Checkout is straightforward, and support is easy to reach after you order.
Are these products for human use?
No. Research Chem Co products are sold strictly for laboratory research use only and are not intended for human consumption, diagnosis, treatment, or prevention of disease.
Can I see product details before ordering?
Product pages show available product details before you order. Contact support with your order number to ask which product- or lot-specific documents are available; a COA is not guaranteed for every item.
Is checkout fast?
Yes. Choose the product, review the total, and enter the details needed to ship and support the order.
What do GLP-1, GLP-2, and GLP-3 mean?
GLP-1 is an incretin hormone whose receptor is studied in several metabolic pathways. GLP-2 is a separate peptide associated mainly with intestinal biology. “GLP-3” is not a formal human peptide category; it is sometimes used informally for triple-agonist research such as retatrutide.
How do I place an order?
Choose a compound, review the strength and product notes, add it to cart, then finish checkout with shipping and payment. If you need help after shipment, contact support with your order number.
