In addition to increasing height in children and adolescents, growth hormone has many other effects on the body: Increases calcium retention, [41] and strengthens and increases the mineralization of bone Increases muscle mass through sarcomere hypertrophy Promotes lipolysis [42] Increases protein synthesis [43] [44] Stimulates the growth of all internal organs excluding the brain Plays a role in homeostasis Reduces liver uptake of glucose Promotes gluconeogenesis in the liver [45] Contributes to the maintenance and function of pancreatic islets Stimulates the immune system Increases deiodination of T4 to T3 [46] Induces insulin resistance [47] Biochemistry [edit] GH has a short biological half-life of about 10 to 20 minutes

Many peptides have low oral bioavailability because stomach acid and digestive enzymes break them down before they are absorbed

and to T

Frequent freezing and thawing can break down peptides

Micronutrients are required in trace levels for biochemical processes such as gene transcription, enzymatic and hormonal reactions, cell protection, signal transduction, and primary and secondary metabolism [6]
