Ipamorelin

Suits people researching the growth hormone axis who want the clean end of the secretagogue class, particularly for recovery and sleep from a single pre-bed shot. It is the usual choice for longer-running protocols, because the older peptides in this class tend to get uncomfortable past a month or so. Best for those comfortable that the mechanism is well established while the recovery, sleep and body-composition uses rest on community experience rather than trials. Like other growth hormone peptides, it is on anti-doping lists at all times.

Ipamorelin is a selective agonist at the ghrelin receptor (GHS-R1a) on the pituitary. Binding triggers a discrete pulse of stored growth hormone that peaks around 40 minutes and settles back to baseline within two to three hours, followed by a rise in IGF-1 (a growth factor) over the next day or so. Because the pulse is short, the body's normal feedback loop stays in place. That is the contrast drawn with oral MK-677, which stimulates the same receptor around the clock, and with injected growth hormone, which bypasses the pituitary altogether.

Reported effects are mostly mild and dose related: a brief head-rush or facial flush within minutes, a heavy or drowsy feeling, mild water retention, a small appetite lift, and injection site reactions. Higher or long-running use can bring tingling in the hands and some drift in how well the body responds to insulin. Going above the saturation dose does not add benefit, it mainly adds these effects, which is why the ladder stops where it does. There is no human safety data past about twelve weeks of continuous use. Purity matters, and a Certificate of Analysis is shared where our supplier provides one.

Supplied freeze-dried. Reconstitute with bacteriostatic water, then refrigerate at 2-8°C and keep it out of the light. Our 5 mg vial reconstituted with 2.5 ml gives 2 mg/ml, which is 20 mcg per click on a pen. We can reconstitute to spec for you as a paid service, or fill a pen.
