What studies have looked at

Each point says who or what was studied and what the study reported, with its source and the date we checked it. These are findings from the sources cited, not advice or a promise of any result.

  • In humans

    In a study of 160 people with acromegaly treated for an average of 425 days, 87 of the 90 treated for 12 months or more reached a normal IGF-1 level. Two had growth of their pituitary tumour, and two stopped because of raised liver enzymes.

  • In humans

    In a real-world observational study of 1,464 adults with acromegaly who took pegvisomant alone for a median of 6 years, 62.3% of those measured had a normal IGF-1 level at their last check. It had no comparison group, and Pfizer staff are among its authors.

How to track it in Peptimes

Add pegvisomant in My Protocols and set the schedule you already follow: days of the week, times of day and a start date. Peptimes never suggests an amount when you log or schedule a dose. Its Library entry shows the status label “FDA Approved”; the entry above gives the product it applies to.

  • Logging: the amount you took and how you feel.
  • Injection sites: each dose records the site, and Insights shows where you’ve injected and how recently. It never suggests where to inject next.
  • Reminders and history: reminders at your times, Dose History, the Calendar and CSV or JSON export work as described on the peptide tracker app page.

Peptimes is a tracking app, not medical advice. Talk to a licensed clinician about your treatment. Peptimes doesn’t sell pegvisomant or any other compound.
