The washout period in between the testosterone treatments was 2 wk. The GH sequence was randomized, and the run-in period for the GH therapy was 3 months.

If the randomization sequence was such that GH therapy was started first, there was a period of GH washout for 4 wk before treatment with transdermal and oral testosterone was recommenced.

The dose of oral testosterone was designed to achieve physiological portal testosterone concentrations without spillover into the systemic circulation. The effects of GH and testosterone on the following variables were studied: Participants were studied after an overnight fast in the early morning in the Clinical Research Facility, Garvan Institute of Medical Research.

Studies were undertaken at baseline and at the end of each treatment period. Methods Protein turnover Whole-body protein metabolism was measured using the leucine turnover technique. The method is based on the principle of steady-state kinetics in which the rates of appearance of substrate equals its rate of disposal.

For leucine, there are two pathways of disposal: In order to make the most of your natural hormones, you must understand how these hormones work synergistically. Once HGH is released into the bloodstream, the hormone travels to the liver and stimulates the production of insulin-like growth factor 1, or IGF-1, and other important growth factors.

Once released into the bloodstream, HGH also stimulates the testes into producing more testosterone. Testosterone is another highly anabolic hormone that has a direct impact on protein synthesis, muscle mass, metabolic function and sexual health. While HGH is known to boost testosterone levels, studies have also found that increased testosterone production will boost HGH.

It appears that these hormones work synergistically and both have positive effects on one another. People who want to enhance their athletic abilities, build muscle and slow the aging process have several options when it comes to supplementation. The problem that many people run into is choosing whether to use a natural testosterone booster or HGH secretagogue.

Many people also wonder if it is safe to use both. There are several reasons for this. Does Testosterone Increase After a Workout?

After that, the levels of both hormones begin a steady decline. If you are experiencing the symptoms listed above, you probably are feeling the influence of the loss of both of these critical hormones, and should take steps to increase the production of both hormones.

The two hormones are synergistic, with each influencing the production of the other. If your testosterone levels are low, it is likely so too will be your HGH levels, and vice versa.

***The Relationship between Natural Testosterone and HGH

Men who wish to feel and look younger, increase their strength and vitality, burn fat, build more lean muscle, and overall slow the aging process, should take steps to increase both HGH and testosterone. Those steps could include supplementation, lifestyle changes, and even hormone replacement therapy for those who qualify.
