A weight-loss compound that acts on two receptors involved in appetite and blood sugar regulation. Studied for weight reduction, improved blood glucose control, and improvements in heart and metabolic health markers. Known for a steadier appetite-suppression curve and fewer gastrointestinal side effects than earlier weight-loss compounds such as Semaglutide.


Compound overview

What it is

Tirzepatide is a dual GLP-1 and GIP receptor agonist. GLP-1 activity slows gastric emptying, reduces appetite, and increases insulin release in response to meals. GIP adds an additional insulinotropic signal and has been shown to reduce GLP-1-related nausea — which is why tirzepatide tends to be better tolerated than pure GLP-1 agonists. Together they produce complementary reductions in food intake and improved glucose metabolism.

Appetite declines progressively as the dose is established. Gastric emptying slows, extending satiety. Post-meal blood glucose spikes flatten out. Over months, visceral and subcutaneous fat both reduce. Most users note fewer gastrointestinal symptoms than with semaglutide at equivalent stages of titration.

Studied outcomes
  • Up to 22.5% body weight reduction in the SURMOUNT-1 phase 3 trial at 72 weeks
  • HbA1c reductions of up to 2.4% in type 2 diabetes trials
  • Significant improvement in blood pressure and lipid profiles
  • Reduction in waist circumference and visceral fat volume
  • Improvement in physical function scores and quality of life measures

Suitability

Who it's for

  • Weight loss with concurrent metabolic support
  • Type 2 diabetes or pre-diabetes alongside excess weight
  • Clients who experienced intolerable GI side effects with semaglutide
  • Long-duration metabolic recomposition protocols
Who should avoid it
  • Personal or family history of medullary thyroid carcinoma or MEN2 syndrome
  • Pregnancy or breastfeeding
  • Active pancreatitis
  • Severe renal impairment (use under close medical supervision)

Dosing guidance

Protocol guidance

Dose
Start at 2.5mg/week for 4 weeks, then increase by 2.5mg every 4 weeks as tolerated to a maximum of 15mg/week
Frequency
Once weekly subcutaneous injection
Cycle length
12–72 weeks; maintenance dosing continues beyond initial loss phase
Route
Subcutaneous injection (abdomen, thigh, or upper arm)
Timing
Same day each week; not meal-dependent

Safety

Contraindications & cautions

  • Slow titration is critical to managing nausea and vomiting
  • Hypoglycaemia risk when used alongside insulin or sulphonylureas
  • May delay oral medication absorption — time medications around dose accordingly
  • Monitor thyroid markers at baseline if there is any thyroid history
  • Dehydration risk if vomiting occurs — maintain hydration

Stacking

Pairs well with

Enhances insulin signalling and metabolic flexibility — synergistic with GIP/GLP-1 dual action

Supports cellular energy and mitochondrial repair during caloric deficit

Targets deep visceral fat via growth hormone release — complementary mechanism for body recomposition
