Common GLP-1 questions.
Which GLP-1 medications does WeightLytic support?
Mounjaro (tirzepatide), Ozempic and Wegovy (semaglutide), Zepbound, Saxenda, Retatrutide and Trulicity. New medications are added as they reach broad availability.
Can I log my doses and injection sites?
Yes. Record each injection with the date, time, dose strength and site, with a rotation map to keep absorption consistent and a complete history you can share with your clinician.
Does WeightLytic recommend or change my dose?
No. WeightLytic never suggests or adjusts medication doses — that decision belongs to you and your prescriber. It records and visualises what is happening so those conversations are better informed.
Can I track side effects and supply?
Yes. Log nausea, fatigue, appetite and mood against each dose to spot patterns, and track how many days of medication you have left with refill alerts before you run out.
Can I share my data with my doctor?
Yes. You can export your medication, weight and symptom history as a clinician-friendly summary to bring to appointments.
Is WeightLytic available yet, and what will it cost?
WeightLytic is available now on iPhone and Android with a free tier; the GLP-1 companion is part of the Pro tier.
