Research Peptides FAQ
Clear, compliant answers focused on research context. This page does not provide dosing, reconstitution, or administration guidance.
Are these “peptides”?
Yes. Tirzepatide, semaglutide, and retatrutide are peptide-based compounds (large molecules built from amino acids). But “peptides” is a broad term—many peptides exist, and only specific ones are regulated as prescription medicines.
Are they the same type of drug?
They are related but different.
Semaglutide: GLP-1 agonist.
Tirzepatide: dual GIP + GLP-1 agonist.
Retatrutide: triple GIP + GLP-1 + glucagon agonist (investigational).
What is tirzepatide?
Tirzepatide is a synthetic, peptide-based medicine that activates two hormone receptors involved in blood sugar regulation and appetite signaling: GIP and GLP-1 (it’s a “dual incretin receptor agonist”).
What is semaglutide?
Semaglutide is a peptide-based GLP-1 receptor agonist (it mimics GLP-1 activity by binding to the GLP-1 receptor).
Semaglutide is the active ingredient in prescription products such as Ozempic (type 2 diabetes) and Wegovy (weight management; and some cardiovascular-risk indications depending on the label).
What is retatrutide?
Retatrutide (also known as LY3437943) is an investigational, peptide-based “triple agonist” that targets GIP, GLP-1, and glucagon receptors.
It has been studied in clinical trials for obesity (and related metabolic outcomes), but it is not FDA-approved as a marketed medicine.
What does “for research purposes only” mean?
It means the item is sold as a research material, not for human or veterinary use, and not for diagnosing, treating, curing, or preventing disease. It should be handled under appropriate lab SOPs and compliance rules.
Do you provide dosing, reconstitution, or injection guidance?
For a research-peptides brand, the safest and most compliant answer is no. Medical dosing and administration information is for licensed healthcare settings and official prescribing information—not for research-product FAQs.
How should research peptides be stored or handled?
Store and handle as directed on the specific box or label instructions. Follow your institution’s SOPs and standard laboratory safety practices (including appropriate PPE, contamination control, traceable labeling, and batch/lot tracking). Avoid any human-use directions.
Do you provide COAs / lab reports?
A strong best practice is: yes—batch/lot-specific COAs when available, with clear matching between the product label and the report.
