01The basics
TZ5 5mg is a once-weekly injectable peptide for blood sugar control and weight loss. The vial contains 5 mg of freeze-dried powder that you mix with bacteriostatic water and inject once a week.
TZ5 acts on two gut hormone receptors, GLP-1 and GIP, and in clinical trials it produced average weight losses of around 15–21%. The 5 mg vial suits the starting phase, when doses are smallest. Here’s how it works, what to watch and the mixing math.

03How it works
TZ5 reduces appetite, slows stomach emptying and improves insulin release when blood sugar is high, by activating both GLP-1 and GIP receptors. With a half-life of about 5 days, one injection a week is enough. Doses are increased gradually because stomach side effects are worst after each increase.
04Half-life
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.
A textbook model built from the half-life alone. Real numbers vary from person to person.
05Clinical reference
Clinical reference. The labeled starting dose is 2.5 mg once a week for 4 weeks, then 5 mg, increasing by 2.5 mg every 4 weeks as needed up to a maximum of 15 mg a week.
Talk to a doctor before use.
Mixing math. Adding 1 ml of bacteriostatic water to the 5 mg vial gives 5 mg per ml. On a U-100 insulin syringe:
The vial holds two starting doses, so a full first month at 2.5 mg needs two vials.

07Injection sites
TZ5 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.
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).

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.

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.

Most people get some stomach side effects early on. A few risks are rare but serious.
Nausea, vomiting, diarrhea and constipation, usually easing as your body adjusts.
Repeated vomiting or diarrhea can dehydrate you and stress your kidneys. Drink plenty of fluids.
Severe stomach pain that won’t go away, sometimes into the back: go to emergency.
Higher gallstone risk with fast weight loss.
Thyroid C-cell tumours occurred in rats; the human risk is unknown.
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
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.
Gliclazide, glyburide and insulin together with a GLP-1 medicine cause low blood sugar more often; doctors usually lower those doses first.
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.
Never use two drugs from this class at the same time (semaglutide, liraglutide, dulaglutide, TZ5, Reta).
Adds to the risk of low blood sugar and of pancreatitis.
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.
