How to track Melanotan II in Peppy

  1. Open the Protocols tab, tap + and search for Melanotan II (or MT-II). Form, unit and typical frequency are prefilled.
  2. Enter your vial size, the water you added and your dose. The inline Calculator shows the units to draw and warns if it will not fit a 1 mL syringe.

  4. On shot day, the Today tab counts down and one tap opens the Log shot sheet with the body map.
  5. Open the protocol to see Active in your system, the half-life curve for what you have logged (Pro).
  6. Log a daily check-in (side effects, feelings, weight) and see it lined up against every dose in Progress.

Frequently asked

How many units is 250 mcg of Melanotan II?

It depends on how the vial was mixed. Example: a 10 mg vial plus 2 mL of bacteriostatic water is 5 mg/mL, so 250 mcg is 0.05 mL, or 5 units on a U-100 insulin syringe. Change the water and the units change. Use the calculator above with your own vial, and verify with your prescriber.

How long does Melanotan II stay in your system?

The Peppy catalog lists a half-life of about 1 hours for Melanotan II. After roughly five half-lives, about 5 hours, most of a single dose has cleared. That is an estimate from the half-life, not a measurement, and individual clearance varies.

Can I track Melanotan II in Peppy?

Yes. Melanotan II is one of 123 compounds built into Peppy, with its form, unit and typical frequency prefilled. Add it as a protocol, set your schedule, and Peppy handles the countdown, the log and the reminders (Pro).

Where should I inject Melanotan II?

Follow your prescriber's instructions. For subcutaneous shots the GLP-1 labels list the abdomen, thigh and upper arm and say to rotate. Peppy's body map has 13 sites, suggests the next one, and shows when each was last used. Read the site rotation guide.
