Overview

TZ5 and TZ-2 are the store’s names for a dual GIP and GLP-1 receptor agonist: one molecule that acts on two gut-hormone receptors involved in appetite and blood sugar.

How it works

By activating both the GIP and GLP-1 receptors it increases insulin release when glucose is high, slows stomach emptying and reduces appetite. A fatty side chain gives it a half-life of about five days.

Chemistry

From PubChem, the US National Library of Medicine’s chemistry database.

GLP-1/GIP dual agonist

Formula: C₂₂₅H₃₄₈N₄₈O₆₈
Molecular weight: 4813 g/mol

Clinical reference

Injection sites

TZ-2 10mg is a freeze-dried powder. After mixing with bacteriostatic water, compounds like this are usually injected subcutaneously (subQ): into the fat just under the skin with a short insulin needle.

Finding it. Anywhere on the belly at least 5 cm from the navel, avoiding scars and the belt line. Pinch a fold of skin and inject into it.

Why it is used. The most-used subcutaneous site: easy to see, plenty of fat and steady absorption. Weekly GLP-1 pens list it first.

Watch out. Move each injection 2 to 3 cm from the last to avoid hard lumps.

Why these sites for TZ-2 10mg

Subcutaneous (subQ)

Belly first. The abdomen has the most fat and the steadiest absorption, and you can see what you are doing.
Short needle, small volume. About 1 ml or less per spot with an insulin syringe. Pinch the skin if you are lean.
Move every time. Keep each injection 2 to 3 cm from the last to avoid lumps.

Every time: wash your hands, wipe the vial stopper and skin with alcohol, use a new sterile needle and syringe, and never share. See a doctor for spreading redness, heat, swelling, pus, fever or numbness. This is general guidance from standard nursing practice, not medical advice; a pharmacist or nurse can show you in person.
