ahhh i knew i had some more info on gh slin
Ok we all know the basic functions of the two hormones, Growth Hormone, and Insulin. I'm just going to point out the relation they have to muscle cells and fat cells.
Insulin promotes the creation of fat cells (lipogenesis)
Growth Hormone fosters the destruction of fat cells (lipolysis)
Growth Hormone counters the effects of insulin. The way it works is this. Insulin is a kind of automatic garage door opener, letting glucose, amino acids, and fats enter the cells. Growth Hormone blunts the receptivity of fat cells to insulin, in effect blocking the electric eye of the garage door opener. By constantly opposing the action of insulin, youthful levels of Growth Hormone keep the cells thin. Without Growth Hormone to inhibit the effects of insulin, the fat cells are free to expand.
Restoring the GH-Insulin balance.
When we are young, our levels of GH are high in relation to insulin. This is good because as we've discussed above, insulin works to create fat cells, while GH works to break down fat for use as energy. GH acts as a brake on insulin, keeping it's fat creation and storage at a minimum. This is why when you were young, you could pig out on pizza and fries and shakes all you wanted without paying the consequences.
Now let's look at what happens when you age. Starting around your mid to late thirties, even in the twenties for some people, you start to put on fat even though your diet and physical activity haven't changed. The reason is that the balance between GH and insulin has shifted. GH has declined while insulin, if anything, has remained the same or even gone up. Insulin is an essential hormone required for the metabolism of sugar. Without it, we die. Insulin also stimulates muscle growth but to a much lesser extent than GH. But with less GH around, insulin is free to turn every calorie you don't immediately expend into fat for later use. Insulin and GH are both our friends; it is the balance between them that is the problem. by bringing GH back to youthful levels--not beyond, which could have negative effects--we can restore the balance between GH and insulin so that they both work together. In this way, when GH and insulin are both in the bloodstream together, they help to stimulate protein synthesis and muscle mass growth. At the same time the higher levels of GH work to block insulin's fat storage effect. And during the postabsorptive phase (which i will discuss in a minute) when insulin disappears from the blood stream, GH can melt away fat without interference.
The Feast-Fast Cycle
The best explanation i can give for how GH works to reduce weight and build muscle is this: With every meal, we go through a three stage cycle of feast and fast. In the first hour after eating (stage 1), the blood sugar rises and insulin is released, which encourages the storage of excess carbs and fat. After the second hour (stage 2), GH is released and the levels of insulin and blood sugar start to fall. At this stage, GH acts to build up muscle protein, an activity that is enhanced by the presence of insulin. In stage 3, known as the postabsorptive phase, which occurs more than 4 hours after eating (the fasting stage), the GH concentrations remain at high levels, while the insulin almost disappears. At this stage, GH acts solely to mobilize the body's fat stores for burning fuel.
To take advantage of the feast fast cycle, you would have to space your meals and snacks so that they are between four and five hours apart. This time interval will allow the insulin to disappear from your bloodstream so that the GH can work unimpeded to build muscle and lean body tissue. This is why i suggest those of you who are using GH for the sake of fat loss and take a.m shots, to try and keep your carb meal as far away from the GH shot as possible.
Mechanism of Fat Loss
Growth Hormone accelerates the burning of fat by making it available as fuel. It is like taking wood from the shed and putting it on the fire. By increasing the free fatty acids, GH makes the fat stores available for energy production. Injections of GH can reduce both the size and amount of fat cells.
Fat cells have GH receptors, and when the GH binds to the receptors, it triggers a series of enzymatic reactions in the cell to break down fat. This as we discussed earlier is called lipolysis. The hormone also gets rid of fat by increasing the energy expenditure overall so that you actually burn more calories faster--a neat metabolic trick.
That's about as plain and simple as i can make it without going into to much detail or specifics.
