It should also be noted that most athletes utilizing HGH are using it in a "cocktail" with (at least) anabolic steroids, and usually with IGF, thyroid meds, and other goodies such as an Aromatase Inhibitor.
Let´s discuss exactly why this is.
Most people who are taking the plunge into HGH use have reached a dead end with their use of anabolics, and need to push through that wall. I´m sure you´ve heard about the synergistic combination of using HGH along with Anabolic Steroids, IGF, insulin and T3 (* usually synthroid, a thyroid medication). The reason is that when these hormones are used correctly together, they´ll produce a large amount of synergy, the insulin is able to shuttle nutrients into your muscle, the thyroid hormone increases your fat-burning capability, the IGF will cause muscle growth as well as helping to grow new cartilage (thus preventing injury), and the anabolic steroids like testosterone, specifically (in addition to being anabolic) can increase IGF-1, in muscle tissue(11), and maybe even increase your body´s ability to use it. Also, usually, an increased amount of IGF usually tells your body to stop producing HGH, but testosterone actually blunts this part of the Negative FeedBack Loop (12)! And the addition of an Aromatase Inhibitor will also stop conversion of testosterone into estrogen; estrogen reduces IGF levels.(13)(14) Finally, the HGH does, well everything I just spent the last few pages telling you about!
Thus, IGF, Testosterone (and of course other steroids), Insulin, thyroid meds, and HGH will all combine to produce a pretty damned effective fat-burning and muscle building cycle! You know what else? HGH is virtually undetectable on any sort of currently used drug-screening tests. HGH, Insulin, Thyroid meds, and IGF may also be used pretty safely by those who may be subject to drug screening tests, or as a non-HPTA suppressive "bridge" between cycles.
Finally, I´ll tell you how I´d take HGH, personally. There was a study done on continuous HGH use vs. every other day injections (ED vs. EOD for the sake of brevity), with a equal total weekly dose. Although it´s counterintuitive, every other day injections produced better total growth in the kids in this (2 and 4 year long) study. Take a look at these graphs:
Growth velocity of children treated with alternate day HGH (the darker bars) or with a daily HGH regimen before, during, and 2 yr after stopping therapy. Values are the mean ± SD. *, P < 0.05; **, P < 0.01.(10)
Here´s another:
Pretreatment and cumulative 4-yr growth velocity of children treated with alternate day HGH ( the darker bars) or with a daily HGH regimen. Values are the mean ± SD. *, P < 0.00 (10)
Shooting HGH every other day more accurately replicates the pulsile frequency of HGH, and thus gave better results for growth (height) deficient children, HGH pulsatility is necessary for proper function of the HGH receptor.(10) Dosing in the EOD nature reduces incidence of any sort of withdrawal problems associated with normal HGH use, including regression or retardation of growth after cessation of therapy.
Therefore, I feel very comfortable speculating that the use of HGH in this manner, which more closely simulates the natural secretion pattern of it, allows the HGH receptors and the rest of the body to more efficiently recover from it, and this will result in much more muscle growth over time (although height was examined in the previous study). My recommendations therefore are 2 shots per day of .028iu/kg of bodyweight, taken every other day, for a minimum of 3months, and preferably for 2-3x that long, and preferably with the other synergistic compounds we´ve just taken a look at.
