Retatrutide, Tirzepatide and Semaglutide reference material
Retatrutide is a synthetic peptide referenced in incretin receptor signalling research at the GLP-1, GIP and glucagon receptors. Tirzepatide is referenced as a dual GIP/GLP-1 receptor research peptide, and Semaglutide is the long-acting GLP-1 reference analogue used in comparative in-vitro work.
All three are supplied by Pondok Peptides as lyophilised research-grade material with batch-specific Certificates of Analysis. Each vial is supplied exclusively for in-vitro laboratory research. Every batch is independently HPLC characterised with a verified Certificate of Analysis, supplied for in-vitro laboratory research only by Pondok Peptides, a UK research peptide supplier.
Why researchers choose Pondok for GLP-1 reference peptides
We commission independent third-party HPLC characterisation on every batch and publish the resulting COA on each product page. Lot numbers on each vial match the certificate, supporting reproducible analytical work.
Discreet packaging, tracked next-day UK dispatch, and a UK-based support team that responds within four working hours. We do not split shipments, we do not substitute lots, and we do not dispatch without a sealed, intact lyophilised cake.
Receptor signalling overview
Semaglutide is referenced as a GLP-1 receptor research peptide. Tirzepatide is referenced for dual GIP and GLP-1 receptor activity in published in-vitro literature. Retatrutide is referenced for activity at GLP-1, GIP and glucagon receptors in current research literature.
Cagrilintide, a long-acting amylin analogue, is frequently studied as a complementary co-agonist alongside Semaglutide in receptor signalling research. Pondok supplies all four for comparative in-vitro work.
Reconstitution and storage
GLP-1 research peptides are supplied as lyophilised powder. Reconstitute with sterile bacteriostatic water at room temperature and store reconstituted material at 2 to 8 degrees Celsius for up to 28 days. Unopened vials should be stored at minus 20 degrees Celsius for long-term stability.
Pair every vial with bacteriostatic water for clean, contamination-free reconstitution. See our blog guide on how to reconstitute peptides for the full step-by-step protocol.
Frequently Asked Questions
Which GLP-1 research peptide has the broadest receptor profile in literature?+
Retatrutide is referenced in current literature as active at GLP-1, GIP and glucagon receptors. Tirzepatide is referenced as a dual GIP/GLP-1 reference peptide, and Semaglutide is the standard single-receptor GLP-1 reference compound.
Are these peptides legal to supply for research in the UK?+
Yes. All compounds are supplied strictly as research chemicals for in-vitro laboratory use only, in line with UK and EU regulations. They are not medicines, supplements or food products.
Do you ship Retatrutide, Tirzepatide and Semaglutide together?+
Yes. Combined orders ship in a single tracked, discreet, temperature-controlled package by next-day UK courier when placed before 3pm.
What purity should I expect?+
All Pondok GLP-1 research peptides are HPLC characterised at a minimum of 98 percent purity, with batch-specific COAs available for download on each product page.
