CJC-1295 copies the natural signal that triggers growth-hormone release, built to last much longer. Early human trials showed growth hormone and IGF-1 stayed higher for days after a single dose.

Follistatin 344 is a binding protein that blocks myostatin, the body’s natural brake on muscle growth. In animal research, raising follistatin led to noticeably more muscle.

GHRP-2 uses the ghrelin signal to release growth hormone. Human studies show it raises both growth hormone and appetite.

GHRP-6 releases growth hormone through the ghrelin signal and is known for a strong boost in hunger. It is discussed for building size and recovery.

Hexarelin is one of the strongest growth-hormone triggers in its class. Rat studies also found it protected heart tissue.

IGF-1 LR3 is a longer-lasting version of IGF-1, one of the body’s main growth signals. Lab research uses it for its strong effect on muscle and cell growth.

Ipamorelin uses the ghrelin signal to release growth hormone, with little effect on stress hormones in animal studies. People look it up for sleep, recovery and body composition.

Kisspeptin-10 is a short form of the natural signal that starts the body’s sex-hormone chain. In human studies it briefly raised LH and testosterone, and it is used in fertility and hormone research.

Sermorelin is a short copy of the body’s own growth-hormone release signal. It was once FDA-approved to test and treat growth hormone deficiency in children, and is still discussed for healthy aging.

Tesamorelin signals the body to release more of its own growth hormone. It is approved as Egrifta to reduce belly fat in adults with HIV-related fat buildup, and is studied for body composition.
