Growth Hormone Secretagogues

Ipamorelin

Also known as: NNC 26-0161

Evidence: Limited human data Disclaimer: Elevated Not FDA-approved
Elevated-disclaimer compound. Not approved by the FDA. Evidence is limited to animal models or small human studies. Safety in humans has not been established.

Mechanism & research context

Selective ghrelin receptor agonist that has been studied for transient growth-hormone release without significant cortisol or prolactin effects in early trials.

Safety flags

0 flags

No curator-recorded safety flags for this entry. Absence of recorded flags is not evidence of safety. Many peptides lack adequate human data.

Doses reported in studies

0 records
This is not a dosing guide. Entries below are historical metadata transcribed verbatim from a cited clinical-trial protocol, published study, or FDA-approved label. They describe what was administered in a specific study population under medical supervision — they are not recommendations, not common-use guidance, and may not be safe or appropriate outside the cited context. Doses widely discussed in community/anecdotal sources are not shown here; see the safety policy for why.

No study-protocol dose records have been curated for Ipamorelin yet. Absence of records is not evidence of safety — many peptides lack adequate human-trial data in the first place.

Records here are populated from public sources only (ClinicalTrials.gov protocol summaries and FDA-approved labels) and must cite a verifiable source URL. They are not added from forum posts, vendor pages, anecdotal write-ups, or social media.

These entries describe what was studied. They do not tell you what to take, how to reconstitute anything, how to fill a capsule, how often to administer, or where to obtain a compound. If you are considering use of Ipamorelin, those decisions belong with a licensed clinician working from the full label or trial record — not from this summary.

Why this page does not list a dose for self-use

The "Doses reported in studies" section above (when populated) describes what was administered in a cited study or label, under medical supervision, in a specific population. It is not a dosing guide for self-use. Separately, we do not publish anecdotal or community-reported dose ranges, administration methods, vial concentrations, or capsule masses for Ipamorelin. Anecdotal figures for unapproved compounds are not harm-reduction data: they lack denominators for adverse events, cannot account for individual physiology or compound purity, and normalise unsupervised use. See the safety policy for the full reasoning.

If this compound has an FDA-approved label

If a label exists, the regulator-reviewed dosing and administration information is there — read it in the context of a prescriber's evaluation.

Questions worth bringing to a clinician

  • What is the evidence for this compound in someone with my history?
  • What are the realistic, regulator-reviewed alternatives?
  • What would you monitor, and what would make you stop?
