Frequently asked questions
Why does GHRP-6 make you so hungry?
GHRP-6 activates the ghrelin receptor (GHS-R1a), which is the same receptor activated by ghrelin — the body's primary hunger hormone. This stimulation in the hypothalamus produces a strong drive to eat, typically within 20-30 minutes of administration. This is considered a side effect for most users but can be beneficial for those trying to gain weight.
Is GHRP-6 better than Ipamorelin?
GHRP-6 produces a stronger GH pulse but also raises cortisol, prolactin, and causes significant hunger. Ipamorelin is more selective — it releases GH without meaningfully affecting cortisol or prolactin, and causes less hunger. Most clinicians now prefer Ipamorelin for its cleaner side effect profile. GHRP-6 may appeal to those specifically wanting appetite stimulation.
Does GHRP-6 have cardioprotective effects?
Animal studies have shown that GHRP-6 has cytoprotective effects on cardiac tissue, potentially reducing damage during ischemia. However, this has not been demonstrated in human clinical trials and should not be considered a reason to use GHRP-6.
