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. online pharmacy steroids Muscles-of-the-body. 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. online pharmacy steroids Steroids forum. 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. online pharmacy steroids Steroid-research. 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. From these studies it is clear that IGF-1 is critical to get maximum anabolic activity from androgens. This means that androgens that increase GH production (i. e. those that aromatize to some degree) will most likely give you the greatest and most rapid gains in muscle mass. Which androgens are tops for BIG gains?So the question now stands, which androgens are best with consideration to GH for maximum muscle tissue growth? Well, the answer is probably the testosterones, specifically esterified versions such as enanthate, cypionate, etc. . Esterification of the testosterone molecule increases it's lipid solubility and leads to a more prolonged release of the drug into the blood stream after deposition in fat tissue. However, the down side to these products is there high incidence of side effects. As explained above, their ability to aromatize and thus increase GH and IGF-1 levels is, in my opinion, part of what makes them superior mass and strength drugs compared to nonaromatizable drugs such as methenolone (Primobolan), stanozolol (Winstrol), and oxandrolone (Anavar) among others. The conversion of testosterone to DHT may also be of some benefit in performance as DHT is known to alter intracellular Ca+ levels through nongenomic mechanisms (i. e.
