Tirzepatide
A dual-action metabolic favourite — powerful appetite and weight support.
What is it?
Tirzepatide is a hugely popular dual-action peptide that works on two gut-hormone pathways (GIP and GLP-1) at once. That two-in-one design has made it one of the most sought-after names for appetite and metabolic goals, right alongside Semaglutide.
Why people choose it
- A top pick in the metabolic peptide world
- Dual-action design (GIP and GLP-1)
- Very popular for appetite and weight goals
- Available in a vial and a convenient pen
What is it used for?
- Appetite and weight goals
- Blood sugar support
- Metabolic health
- Body composition
How it works
Tirzepatide acts on two appetite-and-blood-sugar pathways instead of one, which is why it is so highly regarded in the metabolic space. This dual approach sets it apart from single-pathway options.
Good to know
- Offered as a 10mg vial and an easy 30mg pen.
- Sits alongside Semaglutide and Retatrutide.
- One of the most requested metabolic peptides.

Storage
- Powder (unmixed): −20 °C
- After mixing: 2–8 °C
- Use within: days
- Avoid freeze–thaw cycles
Technique
- Clean the vial stopper and the skin with an alcohol swab and let both air-dry.
- Pinch a skinfold and insert the needle at 45–90° into the subcutaneous tissue.
- Do not aspirate for subcutaneous injections — inject slowly and steadily.
- Wait 5–10 seconds before withdrawing, then apply gentle pressure. Do not rub the site.
- Rotate sites systematically — abdomen (at least 5 cm from the navel), thighs and upper arms — to avoid lipohypertrophy.
- Use a new sterile 28–31 G insulin syringe every time and dispose of it in a sharps container.
Reported side effects
- Nausea
- Diarrhoea
- Vomiting
- Constipation
Safety & evidence
- Gastrointestinal effects are typically mild-to-moderate and dose-dependent; gradual titration reduces them.
- Doses of 12.5–15 mg weekly are used in later phases if tolerated.
- Inject on the same day each week.
