Tirzepatide vs Cagrilintide
Tirzepatide and Cagrilintide are both metabolic peptides, which is why they get recommended interchangeably — but they are different compounds with different origins. A mixed vial also keeps differently: about 56 days for Tirzepatide against 30 for Cagrilintide. The table below sets out the differences. We give no dosing guidance.
Side by side, in plain English — what each one is, where they overlap and where they genuinely differ.

The differences that actually matter
Both are classed as Metabolic peptides, so they get compared constantly and are often researched for overlapping reasons.
Once reconstituted, Tirzepatide keeps noticeably longer than Cagrilintide (~56 days vs ~30 days), so vial waste is a real difference between the two.
What Tirzepatide is
Tirzepatide functions as a dual agonist of the glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. It is important to remember that tirzepatide is a research peptide and is not intended for self-administration or medical use outside of a supervised research or clinical trial context.
What Cagrilintide is
Cagrilintide is a synthetic, long-acting analog of the naturally occurring hormone amylin, which is co-secreted with insulin from pancreatic beta cells. It primarily functions by activating amylin receptors, which are complexes of the calcitonin receptor with receptor activity-modifying proteins (RAMPs 1, 2, or 3), found in various tissues, including the brain. It is crucial to remember that cagrilintide is intended solely for research purposes and is not approved for human therapeutic use outside of controlled cli
How to compare them for yourself
Anecdotes online are noisy because nobody is measuring the same thing. The only comparison that means anything is your own: log each entry with a timestamp, keep the vial ledger honest so you know what you actually got through, pick two or three metrics before you start, and look at the trend after several weeks rather than day to day.
Peptide Wizard does that part for you — Tirzepatide and Cagrilintide are both in the built-in reference library with a 3D vial, and your history, vial ledger and cost per entry stay private on your device.
FAQ
What is the difference between Tirzepatide and Cagrilintide?
Both are classed as Metabolic peptides, so they get compared constantly and are often researched for overlapping reasons.
Can you log Tirzepatide and Cagrilintide in the same period?
Plenty of people record more than one peptide at a time. Peptide Wizard keeps a separate vial ledger and entry history for each, so you can see exactly what overlapped and when — it does not recommend combinations or doses.
Which is better, Tirzepatide or Cagrilintide?
There isn't a universal answer — reported responses vary a lot between individuals, which is why your own log is more informative than anyone else's anecdote. Track one variable at a time and compare your own metrics over several weeks.
