History and Overview of Rus Bio Testosterone (Cypionate)
Testosterone Cypionate is one of the many esterified variants of Testosterone available, and is most likely the second most popular esterified variant (the first being Testosterone Enanthate). It is an injectable form of Testosterone with a slow rate of release and a longer half-life. However, the release rates and half-life of both Testosterone Cypionate and Testosterone Enanthate are very much identical and the two compounds are easily interchangeable (for example, an individual can easily run a 10 week cycle of Testosterone and switch between Testosterone Enanthate and Testosterone Cypionate seamlessly). Testosterone Cypionate possesses a half-life of approximately 12 days while Testosterone Enanthate possesses a half-life of approximately 10 days – hardly much difference. The interesting fact about Testosterone Cypionate, however, is that it seems to have a distinct favor of popularity among American bodybuilders and athletes over the Enanthate variant. These distinctions are not extreme, however, and the commonality of use and availability of both variants is almost equal with Testosterone Enanthate ever so slightly more popular. Neither variant possesses any advantages over the other.
Testosterone Cypionate was first created in the mid-1950s, and was released on the prescription drug market under the brand name Depo-Testosterone and manufactured by UpJohn (however, its brand name at first was labeled as Depo-Testosterone cyclopentylpropionate but was shortened for obvious reasons). Unlike Testosterone Enanthate, which is primarily known as an international item, Testosterone Cypionate is known to be the US answer to the Enanthate variant (although Testosterone Enanthate is utilized almost just as equally in the US). Testosterone Cypionate has held such a positive track record that it is in fact still in production by Upjohn (who merged with Pfizer in 2009) today. As Testosterone Cypionate was the American response to the international product Testosterone Enanthate, many American bodybuilders and athletes throughout the 1960s, 70s, and 80s preferred the use of Testosterone Cypionate over the Enanthate variant for no reason other than the support of an American product, very much akin to an issue of pride (once again, the Cypionate and Enanthate variants of Testosterone are both almost 100% identical and there is no practical reason to prefer one compound over the other).
Side Effects of Rus Bio Testosterone (Cypionate)
As an extremely well-tolerated hormone for most men, the side effects of Rus Bio Testosterone Cypionate are in many ways easy to control. When it comes to such adverse reactions, keep in mind they largely fall into the realm of possible and are by no means guaranteed. Even so, total dosing, genetic predispositions and your overall state of health will play a role.
As for the side effects themselves, Rus Bio Testosterone Cypionate like all testosterone compounds carries a high level of aromatase activity; aromatization referring to the conversion of testosterone into estrogen. As estrogen levels rise, this can lead to gynecomastia (male breast enlargement) and excess water retention. This excess water retention can even negatively affect blood pressure. In-order to combat such effects, especially gynecomastia, many turn to Selective Estrogen Receptor Modulators (SERMs) such as Tamoxifen Citrate (Nolvadex) and for more serious protection Aromatase Inhibitors (AIs) such as Anastrozole (Arimidex). Without question, AIs are the most effective; however, they can also prove to be problematic when it comes to cholesterol and caution is advised.
Beyond these effects,Rus Bio Testosterone Cypionate can promote dihydrotestosterone (DHT) related side effects such as acne, hair loss and prostate enlargement; however, it should go without saying DHT steroids will be the prime culprits. In-order to provide protection, a 5-alpha reductase inhibitor such as Finasteride can be useful as it is an androgen suppressor and the androgen DHT is causing the problem. It must be noted; hair loss is only possible in men predisposed to male pattern baldness.
