Questions (9)

What is Ipamorelin?

Ipamorelin (Ipamorelin (selective GH secretagogue)). Selective ghrelin-receptor (GHS-R) agonist / growth-hormone secretagogue. Stimulates pulsatile GH release with minimal effect on cortisol, prolactin, or appetite vs older GHRPs.

What is Ipamorelin used for?

Commonly discussed uses: GH axis support (research), recovery/sleep (anecdotal), body composition. There is both human and animal/preclinical research, though the depth and quality vary by indication. Note: most uses are not approved indications.

How does Ipamorelin work?

Mechanism: Selective ghrelin-receptor (GHS-R) agonist / growth-hormone secretagogue. Stimulates pulsatile GH release with minimal effect on cortisol, prolactin, or appetite vs older GHRPs.

Is Ipamorelin safe?

Reported considerations: anecdotal: head-rush, flushing, mild headache, injection-site reaction. There is both human and animal/preclinical research, though the depth and quality vary by indication. WADA-prohibited. Not approved for human therapeutic use. This is not a safety endorsement; safety data for unapproved compounds is incomplete.

What is the typical dose of Ipamorelin?

Commonly cited ranges (educational reference, not a recommendation): low 100mcg, typical 200-300mcg per dose, 1-3x/day, high 300mcg 3x/day. Administration: subcutaneous. Half-life: ~2 hours.

Is Ipamorelin legal in Australia?

Australian status: Not ARTG-registered; prescription/research. WADA-prohibited. Not approved for human therapeutic use. General regulatory context: most active peptides are Schedule 4 and require a prescription; import via the Personal Importation Scheme requires a valid Australian prescription for prescription-only goods.

How do you store Ipamorelin?

Reconstitution/storage reference: 2ml BAC water per 5mg vial; storage: reconstituted refrigerated.

What is Ipamorelin commonly stacked with?

Commonly discussed combinations (anecdotal for unapproved compounds): Ipamorelin + CJC-1295 (GH-axis stack). Stacking increases interaction/safety uncertainty.
