01The basics
What TZ-2 5mg is
TZ-2 5mg is the same compound as our TZ5 vials: a once-weekly injectable peptide for appetite, blood sugar and weight control. Each vial holds 5 mg of freeze-dried powder for mixing with bacteriostatic water.
It’s a good size for getting started, when doses are lowest and your body is still adjusting. It works through two hormone pathways, and it’s a powerful medicine with side effects you should plan for. Here’s what to expect in the early weeks.
02Molecule
The molecule
What is actually in the vial or tablet, from the public chemistry databases of the U.S. National Library of Medicine.
03How it works
How it works
TZ-2 activates GLP-1 and GIP receptors. Together, they make you feel full sooner and for longer, slow digestion, and help your pancreas release insulin when blood sugar rises. Most people notice less appetite within the first week or two. Because it lasts about 5 days in the body, one injection a week is enough.
04Half-life
Half-life, in plain numbers
A half-life of about 5 days means half of what is in the body is gone after that time, then half of the rest, and so on. For an injected peptide it reflects how quickly the body breaks the chain down and clears it.
- One half-life
- 5 days
- About 97% gone
- 25 days
- Levels level out with regular use after
- 20 days–25 days
A textbook model built from the half-life alone. Real numbers vary from person to person.
05Clinical reference
Dosing information
Clinical reference. The labeled schedule begins at 2.5 mg once a week for 4 weeks, then 5 mg, and can increase by 2.5 mg every 4 weeks up to 15 mg. Staying at a dose longer is fine if side effects are hard to tolerate.
Talk to a doctor before use.
Mixing math. Adding 0.5 ml of bacteriostatic water to the 5 mg vial gives 10 mg per ml, so every 10 units on a U-100 syringe is 1 mg:
- 2.5 mg = 25 units
- 5 mg = 50 units
The vial holds two 2.5 mg starting doses or one 5 mg dose.

07Injection sites
Where it is injected
TZ-2 5mg arrives as a freeze-dried powder. After it is mixed with bacteriostatic water it is normally injected under the skin, into the fat layer, with a short insulin needle.
1Belly (abdomen)Fat under the skin of the bellySubQ
Volume per siteAbout 1 ml or lessNeedle4–13 mm insulin needle, 29–31G
- Pick a spot at least 5 cm (two finger-widths) from the belly button.
- Avoid scars, stretch marks, bruises and the waistband.
- Pinch up a fold of skin and inject into the fold.
Why it is used. The most fat to work with, easy to see, and the steadiest absorption. Weekly pen medicines list it first.
Careful. Move each injection at least 2–3 cm from the last to avoid firm fatty lumps (lipohypertrophy).

2Front of thighFat under the skin of the thighSubQ
Volume per siteAbout 1 ml or lessNeedle4–13 mm insulin needle, 29–31G
- Sit and look down at the front of your thigh.
- Use the middle band: a hand-width below the hip crease and a hand-width above the knee.
- Pinch the skin and inject into the fold.
Why it is used. Easy to reach while seated, and a handy second area to rotate with the belly.
Careful. It can absorb a little more slowly than the belly; hard leg training straight afterwards can speed it up.

3Back of upper armFat over the tricepsSubQ
Volume per siteAbout 1 ml or lessNeedle4–13 mm insulin needle, 29–31G
- Find the soft, fleshy area at the back of the upper arm.
- Stay halfway between the shoulder and the elbow.
- Pinch the skin and inject into the fold.
Why it is used. A third area to rotate through, so every spot gets a longer rest.
Careful. Hard to pinch and reach with one hand; most people need a helper.

Route for TZ-2 5mgUnder the skin (subQ)
- Same areas as the weekly pensWeekly injectables in this class are labelled for the belly, thigh or back of the arm. Choose an area and move to a fresh spot each week.
- Start with the bellyIt has the most fat and the steadiest absorption, and you can see what you are doing. The thigh and arm are there to rotate into.
- Short needle, small volumeAround 1 ml or less per spot. A 4–13 mm insulin needle reaches the fat without touching muscle; pinch up the skin if you are lean.
- New spot every timeShift 2–3 cm from the last injection. Reusing one spot causes firm lumps that absorb unevenly.
- Wash your hands
- Alcohol on the stopper and skin, let it dry
- New sterile needle and syringe every time
- Never share any of it
- Sharps into a puncture-proof container

Side effects and risks
The first weeks and each dose increase are when side effects are most likely.
Nausea
The most common early side effect. Eat smaller, blander meals and avoid lying down right after eating.
Bowel changes
Diarrhea or constipation; water and fibre help.
Low blood sugar
Mainly if you also take insulin or a sulfonylurea; know the signs.
Pancreas and gallbladder
Severe stomach pain, especially spreading to the back or under the right ribs, needs urgent care.
Thyroid warning
Thyroid C-cell tumours were seen in rats; whether this applies to people is unknown.
Don’t use it if you
Or a family member have had medullary thyroid cancer or MEN 2, you’ve had pancreatitis, have type 1 diabetes, are pregnant, breastfeeding or planning pregnancy, or are under 18.
10Interactions
Interactions
Medicines and substances that change how this product behaves, or that it changes. Show this list to your pharmacist along with everything else you take.
- SeriousInsulin and sulfonylureas
Gliclazide, glyburide and insulin together with a GLP-1 medicine cause low blood sugar more often; doctors usually lower those doses first.
- CautionTablets that need steady levels
Stomach emptying slows, which can change how warfarin, levothyroxine and other narrow-range tablets are absorbed. INR or thyroid levels may need an extra check.
- CautionA second GLP-1 medicine
Never use two drugs from this class at the same time (semaglutide, liraglutide, dulaglutide, TZ5, Reta).
- Good to knowAlcohol
Adds to the risk of low blood sugar and of pancreatitis.
- CautionBirth control pills
For this dual agonist the label warns pills can be less reliable for 4 weeks after starting and after each dose increase; a barrier method covers that gap.
11Bloodwork
Bloodwork checklist
Get a baseline before your first dose, then retest about every 3 months.

- Kidney function
- Liver panel and lipids
- Starting weight and waist, to track progress
12Support
Your first month
- Pick a weekly injection day and stick to it.
- Expect some nausea in week one or two; it usually settles.
- Keep protein high and keep training so the weight you lose is mostly fat.
- Drink plenty of water every day.
- Store the mixed vial in the fridge (2–8 °C) and never freeze it.
