What is Sermorelin?

By Michael 8 months ago

Sermorelin is the acetate salt of an amidated synthetic 29-amino acid peptide (GRF 1-29 NH 2 ) that corresponds to the amino-terminal segment of the naturally occurring human growth hormone-releasing hormone (GHRH or GRF) consisting of 44 amino acid residues.

It stimulates the pituitary gland to naturally produce increased amounts of human growth hormone. Sermorelin Acetate is a truncated analog of a growth hormone releasing factor (GRF 1-44) that is naturally produced by the brain to stimulate pituitary production of human growth hormone. The increased volume of human growth hormone (hGH) produced by the pituitary gland causes an increase in the production of Insulin-Like Growth Factor-1 (IGF-1) by the liver and results in the excellent benefits of this peptide.

Sermorelin, Sleep and the Brain

By Logan 8 months ago

Fifteen years ago, orexins were identified as central regulators of energy homeostasis. Research indicates that orexins are key modulators of the sleep-wake cycle and that these neuropeptides also affect feelings of satiety and hunger. Given their role in energy homeostasis, it was hypothesized that orexin levels are likely regulated, at least in part, by the growth hormone axis. Recent research supports this fact and suggests that growth hormone releasing hormone analogues, such as sermorelin, may be effective in treating conditions in which orexin release is dysfunctional (e.g. narcolepsy) [1].
