As Testosterone Propionate is, of course, Testosterone, it suffers from moderate aromatization which results in the Estrogenic side effects of bloating, water retention, elevated blood pressure (as a result of the bloating), and risks of gynecomastia. This soft and puffy look that bloating brings to the physique is generally undesirable for most users that wish to engage in cutting cycles or lean mass cycles. Therefore, Testosterone Propionate must be utilized with an aromatase inhibitor in order to disable the aromatase enzyme and eliminate the water retention effect of the Estrogen conversion, which should result in a harder looking physique without the soft puffiness. In doing so, Testosterone can successfully be utilized as a ‘hardening’ and cutting compound, as well as for lean mass gains. Some individuals prefer the water retention, convinced that it aids in protecting tissues and connective tissue from the stressors of heavy strength gains and heavy lifting, and therefore Testosterone is preferred as a bulking and strength gaining compound in this case. In any case, Testosterone is also an excellent compound for all-out bulking and strength gaining cycles, which is what its main use seems to be among bodybuilders and athletes. It is a very versatile compound that can provide the anabolic strength necessary for bulking phases.
The . file has one subsection per nonempty gene. Each subsection contains a header line of the form "[gene name] -- [start/end coordinate pairs, comma-separated if necessary] ( [kb length] ) [border description, if necessary]"; this is followed by a blank line, the original report's header line with 'DIST' inserted in front, and the lines in the original report which concerned SNPs in the gene (preceded by [current pos] - [gene start coordinate] DIST values). Subsections are separated by two blank lines.
Testosterone Propionate also converts to both Estrogen (through Aromatization) and Dihydrotestosterone (through 5a-reduction). Most of the side effects people experience with testosterone use is actually from it’s conversion to these two substrates. Thus, hair loss , water retention, acne, and other side effects are possible with use of this drug. Conversion to these hormones is also responsible for some of testosterone’s ability to build muscle; therefore when many side effects are avoided with the use of ancillary compounds, some of the muscle building properties are also stunted.
