What it is
A synthetic pentapeptide growth hormone secretagogue. Supplied as a lyophilized powder.
How it works
Selective agonist of the ghrelin/growth hormone secretagogue receptor (GHS-R1a) in the pituitary, stimulating pulsatile growth hormone release with minimal effect on cortisol or prolactin.
Where it's used
Studied in research settings as a selective growth hormone secretagogue.
Regulatory status
Not FDA-approved; research compound.
Reconstitution
Supplied as a lyophilized powder requiring reconstitution with bacteriostatic water prior to use.
Tracking it
Ipamorelin is injectable, so two things matter in a log: when you dosed and where. Rotating sites and writing both down prevents the classic “did I already pin the left side?” problem. with a half-life of about 2 hours, a dose log also lets a tracker model the relative amount still in your system between doses.
