Tirzepatide reconstitution table

Worked at 5.00 mg, the amount reported in the research for Tirzepatide. Every row is the same arithmetic: milligrams in the vial divided by millilitres of water gives the concentration, and the target amount divided by that concentration gives the volume.

Sample dosing schedule

Goal of the protocol. Produce marked weight and blood-sugar improvements through combined GLP-1 and GIP activity.

Once weekly, subcutaneous. For research reference only, not medical advice.

PhaseAmount
Weeks 1–42.5 mg
Weeks 5–85 mg
Weeks 9–127.5 mg
Weeks 13–1610 mg
Weeks 17–2012.5 mg
Weeks 21+15 mg

Follows the approved label titration; increase every four weeks toward a 5, 10 or 15 mg maintenance amount, chosen by response rather than always pushed to the top.

Higher amounts, more injections. As the weekly total climbs, it is commonly divided into two or more injections across the week, which keeps each shot small and easier to tolerate.

One supplier listed so far for this compound.

List prices, checked September 4, 2026. Sale pricing is ignored on purpose so the table does not swing week to week. Verify before ordering.

Suppliers are listed alphabetically. We do not rank them by price, because the cheapest vial and the one worth buying are rarely the same thing. The column that matters is the last one, and today most of it reads "none on file", including for Quartz Peptides, which is owned by this site’s editor. See the disclosure and the COA guide.

Common questions
How strong is the evidence for Tirzepatide?

We grade it A on a four-point scale. Extensive phase 3 data. Approved as Mounjaro and Zepbound.

What is the half-life of Tirzepatide?

About 5 days. That is the figure the reported dosing frequency follows from.

What amount of Tirzepatide is used in the research?

Weeks 1–4: 2.5 mg. Weeks 5–8: 5 mg. Weeks 9–12: 7.5 mg. Weeks 13–16: 10 mg. Weeks 17–20: 12.5 mg. Weeks 21+: 15 mg. Follows the approved label titration; increase every four weeks toward a 5, 10 or 15 mg maintenance amount, chosen by response rather than always pushed to the top.

How much does Tirzepatide cost?

A 10 mg vial lists at $89 from Quartz Peptides, which works out to $8.90 per mg and about $134 per dose at the amount used in research. Prices checked September 4, 2026. Price is not a quality signal, so check the certificate of analysis before ordering from anyone.

How is Tirzepatide stored once reconstituted?

Refrigerate the mixed vial at 2 to 8 °C, use within a few weeks and avoid freeze and thaw.
