How to track GHK-Cu in Peppy

  1. Open the Protocols tab, tap + and search for GHK-Cu (or Copper Peptide). 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.
  3. Pick a colour and, for injections, a site rotation order. Peppy suggests the next site each time you log.
  4. On shot day, the Today tab counts down and one tap opens the Log shot sheet with the body map.
  5. 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 1 mg of GHK-Cu?

It depends on how the vial was mixed. Example: a 50 mg vial plus 5 mL of bacteriostatic water is 10 mg/mL, so 1 mg is 0.1 mL, or 10 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.

Can I track GHK-Cu in Peppy?

Yes. GHK-Cu 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 GHK-Cu?

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.
