Salve ragazzi secondo voi i gh secretagoghi tipo heraxelin, possono aumentare l' IGF-1???
Avete qualche studio a riguardo aspetto risposte

Saluti Alberto

Non sono direttamente connessi, nel senso che l'igf-1 viene si stimolato dal gh ma quando ci sono abbastanza nutrienti in circolo, altrimenti non funziona.

In senso generale non credo in questi prodotti, costano uno sproposito per risultati che non sono mai garantiti ne supportati da una casistica realmente seria.

bisonerebbe vedere se ci sono studi seri fatti su giovani senza carenza di gh

The role of ghrelin and growth hormone secretagogues receptor on rat adipogenesis.Choi K, Roh SG, Hong YH, Shrestha YB, Hishikawa D, Chen C, Kojima M, Kangawa K, Sasaki S.

Recent research progress indicates a close link between ghrelin, a natural ligand of GH secretagogues receptor (GHS-R), and both the metabolic balance and body composition. To clarify the involvement of ghrelin and GHS-R in the process of adipogenesis, we measured the expression of GHS-R and peroxisome proliferator-activated receptor gamma 2 (PPAR-gamma 2) mRNA in rat adipocytes using semiquantitative RT-PCR methods. The levels of GHS-R mRNA increased by up to 4-fold in adipose tissue from epididymal and parametrial regions as the rat aged from 4-20 wk and were significantly elevated during the differentiation of preadipocytes in vitro. Ghrelin (10(-8) M for 10 d) stimulated the activity of glycerol-3-phosphate dehydrogenase and the differentiation of rat preadipocytes in vitro. Ghrelin treatment also significantly increased the levels of PPAR-gamma 2 mRNA in primary cultured rat differentiated adipocytes. In addition, isoproterenol (10(-8) M, 40 min)-stimulated lipolysis was significantly reduced by simultaneous ghrelin treatment in a dose-dependent manner in vitro. In conclusion, the expression of GHS-R in rat adipocytes increases with the age and during adipogenesis. Ghrelin in vitro stimulates the differentiation of preadipocytes and antagonizes lipolysis. Ghrelin may therefore play an important role in the process of adipogenesis in rats.
