Cycle Planner

Plan by duration to lay out a titration schedule, or plan by supply to see how long the vials you have will last.

Last reviewed 2 May 2026

Starting dose (mg)

Common starters: 0.25 mg semaglutide, 2.5 mg tirzepatide.

Escalation increment (mg)

How much the dose goes up each step. Pick 0 for a constant dose.

Escalation cadence

How often the dose escalates. Most titration protocols use 4 weeks.

Total weeks

How long the cycle runs.

Vial strength (mg)

For working out how many vials you'll need.

Injection frequency

Vials on hand

How many vials you currently have.

Vial strength (mg)

How many mg of peptide is in each vial.

Dose per injection (mg)

The dose you take each time you inject.

Injection frequency

Start date (optional)

If you tell us when you start, we'll work out the run-out date.

Pick your starting dose, escalation, length, and vial size to see your titration schedule.

Where to inject

Most peptide and compounded medications are given subcutaneously - into the layer of fat just below the skin. These are the four sites with reliable fat coverage for most adults.

Anatomical body map showing recommended subcutaneous injection sites on female and male figures: abdomen, upper outer thigh, upper outer buttock, and back of upper arm

Abdomen - the most common site. Stay at least 5 cm from the navel and rotate between left and right.
Upper outer thigh - works well if there is enough fat coverage. Lean men may find this site bony.
Upper outer buttock (gluteal) - reliable fat coverage even on leaner bodies, completely hidden under clothing, and easy to reach across with the opposite hand.
Back of upper arm - usable but harder to self-inject; often needs help from another person.

Rotate sites every injection. Repeated use of the same spot can cause hardened tissue (lipohypertrophy) that affects absorption. See the site rotation guide for a worked rotation schedule.
