01The basics
TZ5 is a once-weekly injectable peptide that improves blood sugar control and supports weight loss. Each vial contains 10 mg of freeze-dried powder for mixing with bacteriostatic water. It’s a dual agonist: it acts on both GLP-1 and GIP receptors, two gut hormones that control appetite and insulin.
In major clinical trials, this compound produced some of the largest weight losses of any approved medicine. It’s also a serious drug: most people get stomach side effects at first, and there are rare but important risks. Because you mix and measure it yourself, the math below matters.

03How it works
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 schedule starts at 2.5 mg once a week for 4 weeks, then increases by 2.5 mg every 4 weeks as tolerated, to a maintenance dose of 5, 10 or 15 mg a week (maximum 15 mg). In the SURMOUNT-1 trial, 15 mg a week produced an average weight loss of about 21% over 72 weeks.
Talk to a doctor before use.
Mixing math. Adding 2 ml of bacteriostatic water to the 10 mg vial gives 5 mg per ml. On a U-100 insulin syringe:
The vial holds four 2.5 mg doses or two 5 mg doses. Write the concentration on the vial.
06Measure it
Type in the amount your prescriber gave you, or the one you are working from, and this turns it into what to draw up or count out from this exact product. It only does the arithmetic; it never suggests an amount.

07Injection sites
TZ5 10mg 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.

Stomach side effects are common and tend to ease. The rest are less common but serious.
Nausea, vomiting, diarrhea and constipation, worst after starting or raising the dose. Severe vomiting can dehydrate you and harm your kidneys.
Severe, persistent stomach pain that may spread to the back: stop and go to an emergency department.
Gallstones are more likely with fast weight loss. Upper-right pain, fever or yellow skin need a doctor.
This compound caused thyroid C-cell tumours in rats; whether it does in humans is unknown. Report a neck lump, hoarseness or trouble swallowing.
Mainly when combined with insulin or sulfonylureas.

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.
11Bloodwork
Test before you start and about every 3 months.

Both are weekly injections. TZ5 also acts on GIP, and in a head-to-head trial it produced more weight loss on average than semaglutide.
