What is Tirzepatide?
A dual GIP/GLP-1 agonist — the most effective weight-loss injection studied to date. Reduces appetite, improves insulin sensitivity, and supports meaningful, sustained loss. Our formulation adds B12 and glycine to reduce side effects and preserve muscle.
What to expect
- A starting dose that steps up — Treatment begins low and increases gradually so your body adjusts and side effects stay manageable.
- Appetite changes first — Most people notice reduced appetite and earlier fullness before they notice the scale moving.
- Steady, not sudden — A healthy pace is roughly one to two pounds a week. Faster is not better.
- Nausea is common early — It usually settles within a few weeks and eases with smaller, slower meals.

Common questions
How is tirzepatide different from semaglutide?
Tirzepatide acts on two gut hormone receptors, GIP and GLP-1, rather than one. In trials it produced greater average weight loss, though individual response varies and side effects are broadly similar.
How often do I inject?
Once weekly, as a small subcutaneous injection at home. This formulation also includes glycine and B12.
How quickly will I lose weight?
Steadily, over months. The early weeks are about stepping the dose up and letting your body adjust rather than chasing the scale.
What are the common side effects?
Nausea, constipation, diarrhoea and reflux are the most common, and are usually worst in the days after a dose increase. Eating smaller portions more slowly helps. Tell your clinician about anything severe or persistent.
What happens if I stop?
Appetite generally returns and weight regain is common without other changes in place. This is why the habits you build during treatment matter as much as the medication.
Who should not take this?
It is not appropriate if you have a personal or family history of medullary thyroid carcinoma or MEN 2, and it is not for use in pregnancy. Your intake covers the full list of contraindications.
