Oral steroid cycles
No, I'm not talking about your first testosterone cycle, I'm talking about puberty. oral steroid cycles Pictures-on-steroids. During puberty there is a disruption in your body's ability to accurately regulate GH levels leading to increased GH, IGF- 1, and insulin levels. This combined with elevated testosterone production characterizes puberty. Research has shown that this disruption is caused by the aromatization of testosterone as well as some direct actions of androgens. oral steroid cycles Pictures-on-steroids. 4,5,6,7,8 In a recent study by Fryburg9 the effects of testosterone and stanozolol were compared for their effects on stimulating GH release. Testosterone enanthate (only 3 mg per kg per week) increased GH levels by 22% and IGF-1 levels by 21% whereas oral stanozolol (0. 1mg per kg per day) had no effect whatsoever on GH or IGF-1 levels. oral steroid cycles Articles on steroid use in sports. A couple of notes about this study. It was only 2-3 weeks long and although stanozolol did not effect GH or IGF-1 levels, it had a similar effect on urinary nitrogen levels. Urinary nitrogen is fraught with confounding variables when used to determine skeletal muscle anabolism and/or catabolism and thus should not be considered an accurate indicator of skeletal muscle growth. Using labeled tracer amino acids as well as 3-methylhistidine is a far more reliable way of determining actual contractile protein synthesis and breakdown respectively. Nevertheless, this study may well explain the observation that many bodybuilders do not respond as well to testosterones with complete estrogenic blockade. Too much Cytadren or especially Arimidex will prevent gyno and probably a little water bloat, but it will also cut into your muscle gains by virtue of a less robust GH burst activity and lower subsequent IGF-1 levels. In vitro have also shown that some androgens increase muscle satellite cells sensitivity to fibroblast growth factor and IGF-1. 10 Remember that satellite cells are required for a muscle cell to grow. Bovine muscle satellite cells were able to fuse 20% more readily when treated with trenbolone and estradiol. 11,12 One may surmise that it was not only the trenbolone but also the estradiol that was causing the significantly increased feed efficiency and muscle growth by way of increased GH and IGF-1 production both in the liver as well as in muscle cells.
