Can end at no pen
Struggling to shift the weight?
The incretin compounds with the largest weight-loss trials — tirzepatide, semaglutide and liraglutide — are in the range as research pens. They are authorised medicines in other countries; these pens are not those medicines and are not supplied as treatment. The Peptide Checkup checks whether your history allows any of them, and which the evidence points to.
01 — Where the Checkup usually lands
3 pens are researched for weight management.
Tirzepatide, semaglutide and liraglutide have large randomised trials for weight and are authorised medicines in several countries. The pens in the range are research products of the same compounds, not the licensed medicines, and the Checkup says so on the result. Your answers decide — including whether to buy at all.

02 — What the Checkup checks
Four things it checks for weight management.
7 minutes of structured questions — categories, not essays — run through a deterministic rules engine against the evidence and regulatory database, then scored against the range.
- 01Which incretin the trials support for your starting point — weekly tirzepatide or semaglutide, or daily liraglutide — and the size of the effect measured
- 02Conditions that matter for incretin compounds, including thyroid cancer history, pancreatitis, gallbladder disease and diabetic eye disease
- 03Interactions with insulin, sulfonylureas and other glucose-lowering medicines, and with medicines absorbed from the gut
- 04The regulatory position — authorised as a medicine elsewhere, a research product here — and what a clinician would monitor
